A method of developing a maximum power point tracking (MPPT) algorithm for photovoltaic (PV) utilizing a peripheral interface controller (PIC) is presented in this paper. The efficiency and adequacy of a PV depend on the temperature and the exposed position to the sun. Thus, there is an optimum point at which the operating power is at maximum. The goal is to operate the PV module at this point (MPP). It can be accomplished by using the MPPT algorithm designed with a DC-DC boost converter. The boost converter, MPPT circuit, PIC18F4550 microcontroller and PV panel are the main components used in this design. The current and voltage produced by the solar panel are observed continuously by a closed-loop control system. The microcontroller-based control system adjusts the duty cycle of the converter to extract the maximum power. With a DC input voltage of 15 V, the boost converter is capable of generating an output voltage of an approximately 60 Vdc at a maximum power of 213.42 W with minimum voltage ripple as compared to 84 W without the MPPT. It proved the effectiveness of the developed algorithm.
A Comparative Study for Different Sizing of Solar PV System under Net Energy ...journalBEEI
Malaysia has moved forward by promoting the use of renewable energy such as solar PV to the public to reduce dependency on fossil fuel-based energy resources. Due to the concern on high electricity bill, Universiti Malaysia Perlis (UniMAP) is keen to install solar PV system as an initiative for energy saving program to its buildings. The objective of this paper is to technically and economically evaluate the different sizing of solar PV system for university buildings under the Net Energy Metering (NEM) scheme. The study involves gathering of solar energy resource information, daily load profile of the buildings, sizing PV array together with grid-connected inverters and the simulation of the designed system using PVsyst software. Based on the results obtained, the amount of solar energy generated and used by the load per year is between 5.10% and 20.20% from the total annual load demand. Almost all solar energy generated from the system will be self-consumed by the loads. In terms of profit gained, the university could reduce its electricity bill approximately between a quarter to one million ringgit per annum depending on the sizing capacity. Beneficially, the university could contribute to the environmental conservation by avoiding up to 2,000 tons of CO2 emission per year.

Comparative Study Improving Residential Load Factor Using Power Shifting and ...TELKOMNIKA JOURNAL
One the problem of electric power stability is due to load fluctuations in distribution system
especialy during peak load conditions. One solution which is applied in Smart Grid scheme is through load
shifting or power shifting. In load shifting the load with high power consumption which operates at peak
load shifted its operations outside of the peak load or s some loads with high power consumption do not
operate at the same time, there is a load whose operating time is shifted to reduce peak power. Power
shifting is used when energy from renewable source not directly suplied to load but storage first and

Solar Photovoltaic (PV) Grid Integration IssuesIJMTST Journal
High electricity demand, reduction in fossil fuels and increasing demand towards solar energy, the integration of solar photovoltaic (PV) generation in the utility grid is gaining high popularity in India. Many distributed energy resources (DERs) are connected to the utility grid or microgrids with the help of power electronics interface, while interfacing power electronics with microgrids there are valid technical concerns from utilities about power quality and the impact of DG on the low voltage (LV) grid. This paper focuses on India’s Current Solar generation capacity and grid integration issues such as voltage, frequency regulation, active, reactive power control and power quality issues.
Multi agent oriented solution for forecasting-based control strategy with loa...Mohamed Ghaieth Abidi
To improve the power supply availability in an island microgrid, this paper proposes a new approach that integrates distributed energy sources economically, reliably and efficiently. In an island mode, a microgrid must ensure its self-sufficiency of energy production since it cannot make an energetic exchange with a main grid. However, in this mode, the random behavior of the resources affected by meteorological factors presents a major constraint. The challenge related to the power availability in microgrids is to find a solution that faces the operation of intermittent power sources. The microgrid should guarantee a useful power management in order to achieve a high availability of energy. In this paper, we present a mathematical model to describe the influence of the meteorological factors on the sources production. We propose a multi-agent control strategy based on the production forecasting and load shedding for a high availability of the microgrid power supply. The proposed multi-agent system uses the master-slave model in which the communication and negotiation between the defined agents are performed by a concept of tokens. The developed control system is implemented on Spartan 6 FPGA-Board. The paper's contribution is applied to a Tunisian petroleum platform where several blackouts are recorded between 2012 and 2014. Simulation and experimental results show clearly a high availability as a performance of the proposed control strategy.
Fuzzy logic control of hybrid systems including renewable energy in microgrids IJECEIAES
With a growing demand for more energy from subscribers, a traditional electric grid is unable to meet new challenges, in the remote areas remains the extension of the conventional electric network very hard to do make prohibitively expensive. Therefore, a new advanced generation of traditional electrical is inevitable and indispensable to move toward an effective, economical, green, clean and self-correcting power system. The most well-known term used to define this next generation power system is micro grid (MG) based on renewable energy sources (RES). Since, the energy produced by RES are not constant at all times, a wide range of energy control techniques must be involved to provide a reliable power to consumers. To solve this problem in this paper we present a fuzzy logic control of isolated hybrid systems (HRES) including renewable energy in micro-grids to maintain a stability in voltage and frequency output especially in the standalone application. The considered HRES combine a wind turbine (WT) and photovoltaic (PV) panels as primary energy sources and an energy storage system (ESS) based on battery as a backup solution. Simulation results obtained from MATLAB/Simulink environment demonstrate the effectiveness of the proposed algorithm in decreasing the electricity bill of customer.

Modelling & Simulation of PV Module Connected with Three-Port DC ConverterDr. Amarjeet Singh
Of the world’s electricity is being generated through conventional sources of energy like coal and atomic energy. People have realized the dire effect of using these fuels, and the amount of CO2 being released into the environment. There has been a shift in emphasis towards cleaner ways of generating electricity in recent years. Solar energy is abundantly available and the cleanest renewable energy source available in the world and is ready to use for a variety of applications, such as the generation of electricity for residential, commercial, or industrial consumption and have become very competitive solutions. It can be seen that there is trend of solar photovoltaics (PV), which has seen rapid growth over the years. The increasing trend of adopting PV system allows consumers to be known as producers or “Prosumers”.
This report evaluates how solar PV can be used in combination with a battery bank along with three port converter to fulfill the requirement. Power production from PV cannot be consistent due to factors like the weather although The main benefits of solar power are that it can be easily installed cost of generation is low as there is no requirement for fuel and require very little maintenance Distributed maximum power point tracking (MPPT) and autonomous are achieved with the proposed configuration. The input-port of each TPC is connected to an independent PV energy source to achieve individual MPPT, and the output-ports of these TPCs are connected with load. Fully modular design is achieved by using Simulink/matlab.
Energy Demand Analysis of Telecom Towers of Nepal with Strategic Scenario Dev...IJRES Journal
Telecom towers, technically known as BTS (Base Transceiver Stations) are the most energy intensive part of cellular network architecture and contribute up to 60 to 80% of total cellular power consumption and varies in response to the real traffic demand throughout the day and night. But, thelack of grid availability highlightsa potential barrier to telecom industry growth in Nepal. Nepal has approximately 5,222 telecom towers of which about 22% do operate on diesel generators (DGs) while the remaining by grid electricity with some shares of renewable energy technologies (RETs: solar and/or wind). Despite the large carbon imprint, the uncertainty in power availability has compelled telecom operators to use DGs to ensure continuous supply of power for the better network availability, which translates huge operating costs along with adverse environmental impact. So, it becomes an imperative solution for telecom operators to evaluate all alternatives in order to increase network reliability with reduced energy cost. This study report intentionally focus on current energy consumptionof such telecom towers and forecast thefuture energydemand with reference to growing subscriber trend up to 2025 using LEAP (Long Range Energy Alternative Planning System)withBusiness As Usual (BAU) scenario. A clean energy technology (CET) scenario with possible RET options is also developed and compared with base case scenario through some policy mechanics on behalf of environmental benefits and sustainable cellular communication. Furthermore, this study concludes a potential energy cum cost saving with RET adoption with basic cost economics analysis.

IRJET-Review on Solar Thermal and Photovoltaic Energy SystemIRJET Journal
This document summarizes and compares solar thermal and photovoltaic energy systems. Solar thermal systems indirectly generate electricity by using solar collectors to heat a liquid or gas, then converting the heat to electricity. Concentrated solar power is a type of solar thermal that uses tracking mechanisms to focus sunlight and achieve higher temperatures and efficiencies. Photovoltaic systems directly convert sunlight into electricity using solar panels without heat exchange. While photovoltaic systems have higher energy production, even at low light levels, their limitation is lack of cost-effective electricity storage. Solar thermal systems allow for thermal energy storage at low cost and therefore can provide dispatchable electricity production. Both systems show potential but differ in energy conversion methods and ability to store excess energy
Stochastic control for optimal power flow in islanded microgridIJECEIAES
The problem of optimal power flow (OPF) in an islanded mircrogrid (MG) for hybrid power system is described. Clearly, it deals with a formulation of an analytical control model for OPF. The MG consists of wind turbine generator, photovoltaic generator, and diesel engine generator (DEG), and is in stochastic environment such as load change, wind power fluctuation, and sun irradiation power disturbance. In fact, the DEG fails and is repaired at random times so that the MG can significantly influence the power flow, and the power flow control faces the main difficulty that how to maintain the balance of power flow? The solution is that a DEG needs to be scheduled. The objective of the control problem is to find the DEG output power by minimizing the total cost of energy. Adopting the Rishel’s famework and using the Bellman principle, the optimality conditions obtained satisfy the Hamilton-Jacobi-Bellman equation. Finally, numerical examples and sensitivity analyses are included to illustrate the importance and effectiveness of the proposed model.

Maximum power point tracking (MPPT) is considered one of the important factors in minimizing the installation costs and improving the efficiency of any photovoltaic water pumping system. The MPPT controller is specifically used to extract the maximum available power from the photovoltaic (PV) array. The maximum power can be achieved by using a specific algorithm. This work aims to raise awareness among farmers about the energy benefits available in the region of Meknes in Morocco, the economic gain and the environmental impact applied to the solar pumping system so that it can be generalized. To obtain the maximum power at each moment, a direct current (DC) water pump (SQF 0-6-2) powered by the solar panels (REC_330NP) through a buck converter was adapted. In addition, this study illustrates the theory of operation of the perturb and observe (P&O) algorithm and simulates the evaluation of this algorithm under different operating conditions (temperature and solar irradiation), and showed the advantages of this system that can operate at the optimal power regardless of disturbances.
IRJET- A Fuzzy Logic Control Method for MPPT to Improve Solar System EfficiencyIRJET Journal
This document presents a fuzzy logic control method for maximum power point tracking (MPPT) to improve the efficiency of solar photovoltaic systems. It proposes using a fuzzy logic controller connected to a boost converter to dynamically adjust the duty cycle based on voltage, current, and power levels from the solar panel. This allows the system to operate at the peak power point despite changing weather conditions. The fuzzy logic controller uses error and change in error as inputs and duty cycle as the output. Simulation results showed this MPPT method can track the maximum power point accurately and outperforms traditional perturbation and observation methods in terms of tracking efficiency and response time.

Multi agent oriented solution for forecasting-based control strategy with loa...Mohamed Ghaieth Abidi
To improve the power supply availability in an island microgrid, this paper proposes a new approach that integrates distributed energy sources economically, reliably and efficiently. In an island mode, a microgrid must ensure its self-sufficiency of energy production since it cannot make an energetic exchange with a main grid. However, in this mode, the random behavior of the resources affected by meteorological factors presents a major constraint. The challenge related to the power availability in microgrids is to find a solution that faces the operation of intermittent power sources. The microgrid should guarantee a useful power management in order to achieve a high availability of energy. In this paper, we present a mathematical model to describe the influence of the meteorological factors on the sources production. We propose a multi-agent control strategy based on the production forecasting and load shedding for a high availability of the microgrid power supply. The proposed multi-agent system uses the master-slave model in which the communication and negotiation between the defined agents are performed by a concept of tokens. The developed control system is implemented on Spartan 6 FPGA-Board. The paper's contribution is applied to a Tunisian petroleum platform where several blackouts are recorded between 2012 and 2014. Simulation and experimental results show clearly a high availability as a performance of the proposed control strategy.
Fuzzy logic control of hybrid systems including renewable energy in microgrids IJECEIAES
With a growing demand for more energy from subscribers, a traditional electric grid is unable to meet new challenges, in the remote areas remains the extension of the conventional electric network very hard to do make prohibitively expensive. Therefore, a new advanced generation of traditional electrical is inevitable and indispensable to move toward an effective, economical, green, clean and self-correcting power system. The most well-known term used to define this next generation power system is micro grid (MG) based on renewable energy sources (RES). Since, the energy produced by RES are not constant at all times, a wide range of energy control techniques must be involved to provide a reliable power to consumers. To solve this problem in this paper we present a fuzzy logic control of isolated hybrid systems (HRES) including renewable energy in micro-grids to maintain a stability in voltage and frequency output especially in the standalone application. The considered HRES combine a wind turbine (WT) and photovoltaic (PV) panels as primary energy sources and an energy storage system (ESS) based on battery as a backup solution. Simulation results obtained from MATLAB/Simulink environment demonstrate the effectiveness of the proposed algorithm in decreasing the electricity bill of customer.

Modelling & Simulation of PV Module Connected with Three-Port DC ConverterDr. Amarjeet Singh
Of the world’s electricity is being generated through conventional sources of energy like coal and atomic energy. People have realized the dire effect of using these fuels, and the amount of CO2 being released into the environment. There has been a shift in emphasis towards cleaner ways of generating electricity in recent years. Solar energy is abundantly available and the cleanest renewable energy source available in the world and is ready to use for a variety of applications, such as the generation of electricity for residential, commercial, or industrial consumption and have become very competitive solutions. It can be seen that there is trend of solar photovoltaics (PV), which has seen rapid growth over the years. The increasing trend of adopting PV system allows consumers to be known as producers or “Prosumers”.
This report evaluates how solar PV can be used in combination with a battery bank along with three port converter to fulfill the requirement. Power production from PV cannot be consistent due to factors like the weather although The main benefits of solar power are that it can be easily installed cost of generation is low as there is no requirement for fuel and require very little maintenance Distributed maximum power point tracking (MPPT) and autonomous are achieved with the proposed configuration. The input-port of each TPC is connected to an independent PV energy source to achieve individual MPPT, and the output-ports of these TPCs are connected with load.

Telecom towers, technically known as BTS (Base Transceiver Stations) are the most energy intensive part of cellular network architecture and contribute up to 60 to 80% of total cellular power consumption and varies in response to the real traffic demand throughout the day and night. But, thelack of grid availability highlightsa potential barrier to telecom industry growth in Nepal. Nepal has approximately 5,222 telecom towers of which about 22% do operate on diesel generators (DGs) while the remaining by grid electricity with some shares of renewable energy technologies (RETs: solar and/or wind). Despite the large carbon imprint, the uncertainty in power availability has compelled telecom operators to use DGs to ensure continuous supply of power for the better network availability, which translates huge operating costs along with adverse environmental impact. So, it becomes an imperative solution for telecom operators to evaluate all alternatives in order to increase network reliability with reduced energy cost. This study report intentionally focus on current energy consumptionof such telecom towers and forecast thefuture energydemand with reference to growing subscriber trend up to 2025 using LEAP (Long Range Energy Alternative Planning System)withBusiness As Usual (BAU) scenario. A clean energy technology (CET) scenario with possible RET options is also developed and compared with base case scenario through some policy mechanics on behalf of environmental benefits and sustainable cellular communication. Furthermore, this study concludes a potential energy cum cost saving with RET adoption with basic cost economics analysis.

IRJET-Review on Solar Thermal and Photovoltaic Energy SystemIRJET Journal
This document summarizes and compares solar thermal and photovoltaic energy systems. Solar thermal systems indirectly generate electricity by using solar collectors to heat a liquid or gas, then converting the heat to electricity. Concentrated solar power is a type of solar thermal that uses tracking mechanisms to focus sunlight and achieve higher temperatures and efficiencies. Photovoltaic systems directly convert sunlight into electricity using solar panels without heat exchange. While photovoltaic systems have higher energy production, even at low light levels, their limitation is lack of cost-effective electricity storage. Solar thermal systems allow for thermal energy storage at low cost and therefore can provide dispatchable electricity production. Both systems show potential but differ in energy conversion methods and ability to store excess energy
Stochastic control for optimal power flow in islanded microgridIJECEIAES
The problem of optimal power flow (OPF) in an islanded mircrogrid (MG) for hybrid power system is described. Clearly, it deals with a formulation of an analytical control model for OPF. The MG consists of wind turbine generator, photovoltaic generator, and diesel engine generator (DEG), and is in stochastic environment such as load change, wind power fluctuation, and sun irradiation power disturbance. In fact, the DEG fails and is repaired at random times so that the MG can significantly influence the power flow, and the power flow control faces the main difficulty that how to maintain the balance of power flow? The solution is that a DEG needs to be scheduled. The objective of the control problem is to find the DEG output power by minimizing the total cost of energy. Adopting the Rishel’s famework and using the Bellman principle, the optimality conditions obtained satisfy the Hamilton-Jacobi-Bellman equation. Finally, numerical examples and sensitivity analyses are included to illustrate the importance and effectiveness of the proposed model.

Maximum power point tracking (MPPT) is considered one of the important factors in minimizing the installation costs and improving the efficiency of any photovoltaic water pumping system. The MPPT controller is specifically used to extract the maximum available power from the photovoltaic (PV) array. The maximum power can be achieved by using a specific algorithm.

A cost-effective and optimized maximum powerpoint tracking system for the pho...IJECEIAES
Solar energy is naturally available from sun, and it can be extracted by using a photovoltaic (PV) cell. However, solar energy extraction entirely depends on the climatic conditions and angle of rays falling on PV cells. Hence, maximum powerpoint tracking (MPPT) is considered in most areas under variable climatic conditions, which acts as a controller unit for PV cells. MPPT can enhance the efficiency of PV cells. However, designing an MPPT model is challenging as different uncertainties in the climatic condition may lead to more fluctuations in voltage and current in PV cells. Under the shaded condition, the PV cell may have other MPPT points that lead to the PV cell’s low efficiency in analyzing maximum power. Hence, this paper introduces a cost-effective and optimized system for the PV model that can find optimal power and improve PV cells’ efficiency. The proposed system achieves better computational performance with ~35% and ~42% than existing MPPT techniques. The improved particle swarm optimization (PSO) is smoother due to the enhanced form of MPP tracking. Hence, improved PSO takes 0.038 sec while the existing PSO technique takes 0.045 sec to obtain the MPP tracking.

Whenever a product is purchased on an e-commerce platform, people leave their reviews about the product. These reviews are very helpful for the store owners and the product’s manufacturers for the betterment of their work process as well as product quality. An automated system is proposed in this work that operates on two datasets D1 and D2 obtained from Amazon. After certain preprocessing steps, N-gram and word embedding-based features are extracted using term frequency-inverse document frequency (TF-IDF), bag of words (BoW) and global vectors (GloVe), and Word2vec, respectively. Four machine learning (ML) models support vector machines (SVM), logistic regression (RF), logistic regression (LR), multinomial Naïve Bayes (MNB), two deep learning (DL) models convolutional neural network (CNN), long-short term memory (LSTM), and standalone bidirectional encoder representations (BERT) are used to classify reviews as either positive or negative. The results obtained by the standard ML, DL models and BERT are evaluated using certain performance evaluation measures. BERT turns out to be the best-performing model in the case of D1 with an accuracy of 90% on features derived by word embedding models while the CNN provides the best accuracy of 97% upon word embedding features in the case of D2. The proposed model shows better overall performance on D2 as compared to D1.
Design, simulation, and analysis of microstrip patch antenna for wireless app...TELKOMNIKA JOURNAL
In this study, a microstrip patch antenna that works at 3.6 GHz was built and tested to see how well it works. In this work, Rogers RT/Duroid 5880 has been used as the substrate material, with a dielectric permittivity of 2.2 and a thickness of 0.3451 mm; it serves as the base for the examined antenna. The computer simulation technology (CST) studio suite is utilized to show the recommended antenna design. The goal of this study was to get a more extensive transmission capacity, a lower voltage standing wave ratio (VSWR), and a lower return loss, but the main goal was to get a higher gain, directivity, and efficiency. After simulation, the return loss, gain, directivity, bandwidth, and efficiency of the supplied antenna are found to be -17.626 dB, 9.671 dBi, 9.924 dBi, 0.2 GHz, and 97.45%, respectively. Besides, the recreation uncovered that the transfer speed side-lobe level at phi was much better than those of the earlier works, at -28.8 dB, respectively. Thus, it makes a solid contender for remote innovation and more robust communication.

This document describes using a snake optimization algorithm to tune the gains of an enhanced proportional-integral controller for congestion avoidance in a TCP/AQM system. The controller aims to maintain a stable and desired queue size without noise or transmission problems. A linearized model of the TCP/AQM system is presented. An enhanced PI controller combining nonlinear gain and original PI gains is proposed. The snake optimization algorithm is then used to tune the parameters of the enhanced PI controller to achieve optimal system performance and response. Simulation results are discussed showing the proposed controller provides a stable and robust behavior for congestion control.
Improving the detection of intrusion in vehicular ad-hoc networks with modifi...TELKOMNIKA JOURNAL
Vehicular ad-hoc networks (VANETs) are wireless-equipped vehicles that form networks along the road. The security of this network has been a major challenge. The identity-based cryptosystem (IBC) previously used to secure the networks suffers from membership authentication security features. This paper focuses on improving the detection of intruders in VANETs with a modified identity-based cryptosystem (MIBC). The MIBC is developed using a non-singular elliptic curve with Lagrange interpolation. The public key of vehicles and roadside units on the network are derived from number plates and location identification numbers, respectively. Pseudo-identities are used to mask the real identity of users to preserve their privacy. The membership authentication mechanism ensures that only valid and authenticated members of the network are allowed to join the network. The performance of the MIBC is evaluated using intrusion detection ratio (IDR) and computation time (CT) and then validated with the existing IBC. The result obtained shows that the MIBC recorded an IDR of 99.3% against 94.3% obtained for the existing identity-based cryptosystem (EIBC) for 140 unregistered vehicles attempting to intrude on the network. The MIBC shows lower CT values of 1.17 ms against 1.70 ms for EIBC. The MIBC can be used to improve the security of VANETs.
Conceptual model of internet banking adoption with perceived risk and trust f...TELKOMNIKA JOURNAL
Understanding the primary factors of internet banking (IB) acceptance is critical for both banks and users; nevertheless, our knowledge of the role of users’ perceived risk and trust in IB adoption is limited. As a result, we develop a conceptual model by incorporating perceived risk and trust into the technology acceptance model (TAM) theory toward the IB. The proper research emphasized that the most essential component in explaining IB adoption behavior is behavioral intention to use IB adoption. TAM is helpful for figuring out how elements that affect IB adoption are connected to one another. According to previous literature on IB and the use of such technology in Iraq, one has to choose a theoretical foundation that may justify the acceptance of IB from the customer’s perspective. The conceptual model was therefore constructed using the TAM as a foundation. Furthermore, perceived risk and trust were added to the TAM dimensions as external factors. The key objective of this work was to extend the TAM to construct a conceptual model for IB adoption and to get sufficient theoretical support from the existing literature for the essential elements and their relationships in order to unearth new insights about factors responsible for IB adoption.
Efficient combined fuzzy logic and LMS algorithm for smart antennaTELKOMNIKA JOURNAL
The smart antennas are broadly used in wireless communication. The least mean square (LMS) algorithm is a procedure that is concerned in controlling the smart antenna pattern to accommodate specified requirements such as steering the beam toward the desired signal, in addition to placing the deep nulls in the direction of unwanted signals. The conventional LMS (C-LMS) has some drawbacks like slow convergence speed besides high steady state fluctuation error. To overcome these shortcomings, the present paper adopts an adaptive fuzzy control step size least mean square (FC-LMS) algorithm to adjust its step size. Computer simulation outcomes illustrate that the given model has fast convergence rate as well as low mean square error steady state.
Design and implementation of a LoRa-based system for warning of forest fireTELKOMNIKA JOURNAL
This paper presents the design and implementation of a forest fire monitoring and warning system based on long range (LoRa) technology, a novel ultra-low power consumption and long-range wireless communication technology for remote sensing applications. The proposed system includes a wireless sensor network that records environmental parameters such as temperature, humidity, wind speed, and carbon dioxide (CO2) concentration in the air, as well as taking infrared photos.The data collected at each sensor node will be transmitted to the gateway via LoRa wireless transmission. Data will be collected, processed, and uploaded to a cloud database at the gateway. An Android smartphone application that allows anyone to easily view the recorded data has been developed. When a fire is detected, the system will sound a siren and send a warning message to the responsible personnel, instructing them to take appropriate action. Experiments in Tram Chim Park, Vietnam, have been conducted to verify and evaluate the operation of the system.
Wavelet-based sensing technique in cognitive radio networkTELKOMNIKA JOURNAL
Cognitive radio is a smart radio that can change its transmitter parameter based on interaction with the environment in which it operates. The demand for frequency spectrum is growing due to a big data issue as many Internet of Things (IoT) devices are in the network. Based on previous research, most frequency spectrum was used, but some spectrums were not used, called spectrum hole. Energy detection is one of the spectrum sensing methods that has been frequently used since it is easy to use and does not require license users to have any prior signal understanding. But this technique is incapable of detecting at low signal-to-noise ratio (SNR) levels. Therefore, the wavelet-based sensing is proposed to overcome this issue and detect spectrum holes. The main objective of this work is to evaluate the performance of wavelet-based sensing and compare it with the energy detection technique. The findings show that the percentage of detection in wavelet-based sensing is 83% higher than energy detection performance. This result indicates that the wavelet-based sensing has higher precision in detection and the interference towards primary user can be decreased.
A novel compact dual-band bandstop filter with enhanced rejection bandsTELKOMNIKA JOURNAL
In this paper, we present the design of a new wide dual-band bandstop filter (DBBSF) using nonuniform transmission lines. The method used to design this filter is to replace conventional uniform transmission lines with nonuniform lines governed by a truncated Fourier series. Based on how impedances are profiled in the proposed DBBSF structure, the fractional bandwidths of the two 10 dB-down rejection bands are widened to 39.72% and 52.63%, respectively, and the physical size has been reduced compared to that of the filter with the uniform transmission lines. The results of the electromagnetic (EM) simulation support the obtained analytical response and show an improved frequency behavior.
Deep learning approach to DDoS attack with imbalanced data at the application...TELKOMNIKA JOURNAL
A distributed denial of service (DDoS) attack is where one or more computers attack or target a server computer, by flooding internet traffic to the server. As a result, the server cannot be accessed by legitimate users. A result of this attack causes enormous losses for a company because it can reduce the level of user trust, and reduce the company’s reputation to lose customers due to downtime. One of the services at the application layer that can be accessed by users is a web-based lightweight directory access protocol (LDAP) service that can provide safe and easy services to access directory applications. We used a deep learning approach to detect DDoS attacks on the CICDDoS 2019 dataset on a complex computer network at the application layer to get fast and accurate results for dealing with unbalanced data. Based on the results obtained, it is observed that DDoS attack detection using a deep learning approach on imbalanced data performs better when implemented using synthetic minority oversampling technique (SMOTE) method for binary classes. On the other hand, the proposed deep learning approach performs better for detecting DDoS attacks in multiclass when implemented using the adaptive synthetic (ADASYN) method.
The appearance of uncertainties and disturbances often effects the characteristics of either linear or nonlinear systems. Plus, the stabilization process may be deteriorated thus incurring a catastrophic effect to the system performance. As such, this manuscript addresses the concept of matching condition for the systems that are suffering from miss-match uncertainties and exogeneous disturbances. The perturbation towards the system at hand is assumed to be known and unbounded. To reach this outcome, uncertainties and their classifications are reviewed thoroughly. The structural matching condition is proposed and tabulated in the proposition 1. Two types of mathematical expressions are presented to distinguish the system with matched uncertainty and the system with miss-matched uncertainty. Lastly, two-dimensional numerical expressions are provided to practice the proposed proposition. The outcome shows that matching condition has the ability to change the system to a design-friendly model for asymptotic stabilization.

Many systems, including digital signal processors, finite impulse response (FIR) filters, application-specific integrated circuits, and microprocessors, use multipliers. The demand for low power multipliers is gradually rising day by day in the current technological trend. In this study, we describe a 4×4 Wallace multiplier based on a carry select adder (CSA) that uses less power and has a better power delay product than existing multipliers. HSPICE tool at 16 nm technology is used to simulate the results. In comparison to the traditional CSA-based multiplier, which has a power consumption of 1.7 µW and power delay product (PDP) of 57.3 fJ, the results demonstrate that the Wallace multiplier design employing CSA with first zero finding logic (FZF) logic has the lowest power consumption of 1.4 µW and PDP of 27.5 fJ.
Evaluation of the weighted-overlap add model with massive MIMO in a 5G systemTELKOMNIKA JOURNAL
The flaw in 5G orthogonal frequency division multiplexing (OFDM) becomes apparent in high-speed situations. Because the doppler effect causes frequency shifts, the orthogonality of OFDM subcarriers is broken, lowering both their bit error rate (BER) and throughput output. As part of this research, we use a novel design that combines massive multiple input multiple output (MIMO) and weighted overlap and add (WOLA) to improve the performance of 5G systems. To determine which design is superior, throughput and BER are calculated for both the proposed design and OFDM. The results of the improved system show a massive improvement in performance ver the conventional system and significant improvements with massive MIMO, including the best throughput and BER. When compared to conventional systems, the improved system has a throughput that is around 22% higher and the best performance in terms of BER, but it still has around 25% less error than OFDM.

In this study, it is aimed to obtain two different asymmetric radiation patterns obtained from antennas in the shape of the cross-section of a parabolic reflector (fan blade type antennas) and antennas with cosecant-square radiation characteristics at two different frequencies from a single antenna. For this purpose, firstly, a fan blade type antenna design will be made, and then the reflective surface of this antenna will be completed to the shape of the reflective surface of the antenna with the cosecant-square radiation characteristic with the frequency selective surface designed to provide the characteristics suitable for the purpose. The frequency selective surface designed and it provides the perfect transmission as possible at 4 GHz operating frequency, while it will act as a band-quenching filter for electromagnetic waves at 5 GHz operating frequency and will be a reflective surface. Thanks to this frequency selective surface to be used as a reflective surface in the antenna, a fan blade type radiation characteristic at 4 GHz operating frequency will be obtained, while a cosecant-square radiation characteristic at 5 GHz operating frequency will be obtained.
Reagentless iron detection in water based on unclad fiber optical sensorTELKOMNIKA JOURNAL
A simple and low-cost fiber based optical sensor for iron detection is demonstrated in this paper. The sensor head consist of an unclad optical fiber with the unclad length of 1 cm and it has a straight structure. Results obtained shows a linear relationship between the output light intensity and iron concentration, illustrating the functionality of this iron optical sensor. Based on the experimental results, the sensitivity and linearity are achieved at 0.0328/ppm and 0.9824 respectively at the wavelength of 690 nm. With the same wavelength, other performance parameters are also studied. Resolution and limit of detection (LOD) are found to be 0.3049 ppm and 0.0755 ppm correspondingly. This iron sensor is advantageous in that it does not require any reagent for detection, enabling it to be simpler and cost-effective in the implementation of the iron sensing.

In place of the commercial Pt electrode used in quantum sensitized solar cells, the low-cost CuS cathode is created using electrophoresis. High resolution scanning electron microscopy and X-ray diffraction were used to analyze the structure and morphology of structural cubic samples with diameters ranging from 40 nm to 200 nm. The conversion efficiency of solar cells is significantly impacted by the calcination temperatures of cathodes at 100 °C, 120 °C, 150 °C, and 180 °C under vacuum. The fluorine doped tin oxide (FTO)/CuS cathode electrode reached a maximum efficiency of 3.89% when it was calcined at 120 °C. Compared to other temperature combinations, CuS nanoparticles crystallize at 120 °C, which lowers resistance while increasing electron lifetime.

This article discusses the progressive learning for structural tolerance online sequential extreme learning machine (PSTOS-ELM). PSTOS-ELM can save robust accuracy while updating the new data and the new class data on the online training situation. The robustness accuracy arises from using the householder block exact QR decomposition recursive least squares (HBQRD-RLS) of the PSTOS-ELM. This method is suitable for applications that have data streaming and often have new class data. Our experiment compares the PSTOS-ELM accuracy and accuracy robustness while data is updating with the batch-extreme learning machine (ELM) and structural tolerance online sequential extreme learning machine (STOS-ELM) that both must retrain the data in a new class data case. The experimental results show that PSTOS-ELM has accuracy and robustness comparable to ELM and STOS-ELM while also can update new class data immediately.
Electroencephalography-based brain-computer interface using neural networksTELKOMNIKA JOURNAL
This study aimed to develop a brain-computer interface that can control an electric wheelchair using electroencephalography (EEG) signals. First, we used the Mind Wave Mobile 2 device to capture raw EEG signals from the surface of the scalp. The signals were transformed into the frequency domain using fast Fourier transform (FFT) and filtered to monitor changes in attention and relaxation. Next, we performed time and frequency domain analyses to identify features for five eye gestures: opened, closed, blink per second, double blink, and lookup. The base state was the opened-eyes gesture, and we compared the features of the remaining four action gestures to the base state to identify potential gestures. We then built a multilayer neural network to classify these features into five signals that control the wheelchair’s movement. Finally, we designed an experimental wheelchair system to test the effectiveness of the proposed approach. The results demonstrate that the EEG classification was highly accurate and computationally efficient. Moreover, the average performance of the brain-controlled wheelchair system was over 75% across different individuals, which suggests the feasibility of this approach.
Adaptive segmentation algorithm based on level set model in medical imagingTELKOMNIKA JOURNAL
For image segmentation, level set models are frequently employed. It offer best solution to overcome the main limitations of deformable parametric models. However, the challenge when applying those models in medical images stills deal with removing blurs in image edges which directly affects the edge indicator function, leads to not adaptively segmenting images and causes a wrong analysis of pathologies wich prevents to conclude a correct diagnosis. To overcome such issues, an effective process is suggested by simultaneously modelling and solving systems’ two-dimensional partial differential equations (PDE). The first PDE equation allows restoration using Euler’s equation similar to an anisotropic smoothing based on a regularized Perona and Malik filter that eliminates noise while preserving edge information in accordance with detected contours in the second equation that segments the image based on the first equation solutions. This approach allows developing a new algorithm which overcome the studied model drawbacks. Results of the proposed method give clear segments that can be applied to any application. Experiments on many medical images in particular blurry images with high information losses, demonstrate that the developed approach produces superior segmentation results in terms of quantity and quality compared to other models already presented in previeous works.
Automatic channel selection using shuffled frog leaping algorithm for EEG bas...TELKOMNIKA JOURNAL
Drug addiction is a complex neurobiological disorder that necessitates comprehensive treatment of both the body and mind. It is categorized as a brain disorder due to its impact on the brain. Various methods such as electroencephalography (EEG), functional magnetic resonance imaging (FMRI), and magnetoencephalography (MEG) can capture brain activities and structures. EEG signals provide valuable insights into neurological disorders, including drug addiction. Accurate classification of drug addiction from EEG signals relies on appropriate features and channel selection. Choosing the right EEG channels is essential to reduce computational costs and mitigate the risk of overfitting associated with using all available channels. To address the challenge of optimal channel selection in addiction detection from EEG signals, this work employs the shuffled frog leaping algorithm (SFLA). SFLA facilitates the selection of appropriate channels, leading to improved accuracy. Wavelet features extracted from the selected input channel signals are then analyzed using various machine learning classifiers to detect addiction. Experimental results indicate that after selecting features from the appropriate channels, classification accuracy significantly increased across all classifiers. Particularly, the multi-layer perceptron (MLP) classifier combined with SFLA demonstrated a remarkable accuracy improvement of 15.78% while reducing time complexity.

A method of developing a maximum power point tracking (MPPT) algorithm
for photovoltaic (PV) utilizing a peripheral interface controller (PIC) is
presented in this paper. The efficiency and adequacy of a PV depend on
the temperature and the exposed position to the sun. Thus, there is an optimum
point at which the operating power is at maximum. The goal is to operate
the PV module at this point (MPP). It can be accomplished by using the MPPT
algorithm designed with a DC-DC boost converter. The boost converter,
MPPT circuit, PIC18F4550 microcontroller and PV panel are the main
components used in this design. The current and voltage produced by the solar
panel are observed continuously by a closed-loop control system.
The microcontroller-based control system adjusts the duty cycle of
the converter to extract the maximum power. With a DC input voltage of
15 V, the boost converter is capable of generating an output voltage of
an approximately 60 Vdc at a maximum power of 213.42 W with minimum
voltage ripple as compared to 84 W without the MPPT. It proved
the effectiveness of the developed algorithm.

1. INTRODUCTION
Lately, the exploratory and open mindfulness on ecological and energy problems has acquired real
attention to the examination of cutting-edge innovations, especially in very useful innovation [1]. Energy is an
essential component for the society and monetary advancement of social orders. The usage scale of energy
means that the financial flourishing of a country.
In Malaysia, the developing industrialization and expanding way of life have extensively expanded
the use of energy. Malaysian energy utilization has risen significantly in recent years due to the joined requests
of industrialization and urbanization [1]. Due to the expansion of energy utilization, there are growing concerns
about energy use and its effects that are not friendly to the earth. Normal and productive use of energy assets

bears exceptional significance too. The point of the exploration is to examine the energy request, supply,
utilization, ecological effect and also audit the future energy assets.
Energy is a fundamental requirement for the development, commercial development, modernization
and mechanization [2]. Therefore, energy demand throughout the world is expanding rapidly, and this global
demand must be considered to meet energy concerns for the future. The world promoted power request is
demonstrated in Figure 1. Politically influential nation request ascends from 145 billion MW in 2007 and
expected to be 218 billion MW in 2035, which means 49 per cent increment. That leads to more installation of
power plants [3].
The Intergovernmental Climate Change Panel has reported that the main hazardous issue is global
warming [4]. Since then, many governments, institutions and the responsive public in general, have set
a clear mission to save the earth from all severe issues caused by the conventional power generation
stations [5-9]. Since emanations are depending on the utilization of fossil fuel, so the efforts are focused on
the projects of developing efficient renewable energy generation stations such as solar fields [10].
Figure 1. World power demand [1]
a. Renewable energy potentiality in Malaysia
The conventional energy sources are being depleted aggressively because of the high consumption of
energy for the various applications in our daily life. Therefore, alternative renewable sources are particularly
essential for future energy requests. At the same time, the governments and research institutes are under
pressure to meet the goal of supplying all humanity demands with the alternative sources.
Recently, utilizing a renewable source of energy is getting more popular, especially solar energy,
which is the most potent source of alternative energy in this country and also in some other countries. Catching
sunlight and transforming it into electricity for everyday utilization is a smart plan, and the photovoltaic
systems have been used in Malaysia since the 1980s [10]. PV technology is developing quickly because of
the increased attention and awareness to climate changes, thinner ozone layer and carbon pollution.
The average solar radiation is 400 to 600 MJ/m2 in Malaysia [11]. It was aimed by the Malaysian government
from the tenth plan from 2011-2015 to have fields that contribute by 5.5 per cent of the total power generation
mix [12]. As indicated by the Malaysian government report. There will been around 50-80 per cent in the first
project (residential areas) will been provided by solar PV [13].
b. Challenges of using MPPT algorithm for PV generators
As people are anxious about the fossil fuel contaminations and the fundamental issues brought
by using it for power generation, renewable energy sources, especially photovoltaic (PV) are currently utilized.
The solar board is utilized, which comprises PV cells. These cells retain the energy from sunlight. PV
generators are being used as a part of numerous applications, for example, battery charging, light sources, water
pumping, space stations powering. The solar board has the advantages of requiring less maintenance and being
contamination free. However, they have some drawbacks as they are manufactured with the high cost and low
energy conversion efficiency [14-16]. Therefore, the PV system must deliver the maximum available power to
the load, thus increasing the PV efficiency [17-21].
Since the PV modules still have generally low change effectiveness, the overall system cost can be
lessened by utilizing high productivity power trackers that are intended to extract the most extreme conceivable
power from the PV module. The process of extracting the most powerpoint itself is challenging and always
remains a significant challenge in the literature [22]. Different MPPT algorithms have been proposed to
maximize PV power. Designing PV systems need to consider the power flow such that the power transfer from
the source to the load is of the highest possible and most stable [23]. One must take into account that the power
generated by these panels depends on the weather conditions such as irradiance and temperature [23]. A PV

system without the integration of an MPPT function exposes the connected load at risk due to the voltage
fluctuation [24]. It also leads to waste in PV power as the PV system is unable to extract maximum power from
the PV module. Hence, the need for the MPPT controller is deemed necessary [24-25].
Continuous estimations of PV board open-circuit voltage are utilized to recognize the most extreme
power outcome of the solar board. The battery charge rate is persistently balanced in a way that the system
working point is powered close to the identified most extreme power outcome of the solar board. Hypothetical
and exploratory investigations are utilized to show the steady quality and feasibility of the proposed method.
2. MPPT METHODS
As mentioned earlier, using solar energy is an active topic which has been discussed by many
researchers throughout the world. In-state of the art, it is agreed upon that the solar cells operate with low
efficiency. Therefore, the challenge is to find the best possible technique to improve the efficiency of those
cells. A maximum power point tracking (MPPT) is an appreciated development in this field. Many methods
have been utilized for MPP tracking. Several methods are discussed in details and benchmarked in this section.
For example, perturb and observe method [26], incremental conductance method [27], constant voltage
method [28] and short-current pulse method [29]. An alternative method in the extracting of the maximum
possible power from the PV panel is through the integration of the MPPT circuit into the system. The concept
of the circuit simplicity which integrates the programmable interface controller (PIC) microcontroller is
the main sign of this method.
2.1. Perturb and observe method
This method is widely used for MPPT as it requires less number of sensors and has been discussed by
many researchers. The idea behind this method is to modify the converter's duty cycle. It will being indicate a
change in the panel voltage. In this method, the voltage on both sides of the maximum power point will being
developed increasingly and decreasingly with observing the generated power until the optimum value is gained
with repeating this process each tracking step till the MPP is reached.
Once the MPP is reached, the algorithm oscillates about the right value. The step used for increasing
and decreasing the voltage is a fixed step as it should not be small so that the tracking process is not slow,
albeit it helps to reduce oscillation. On the other hand, it also should not be a big step to reduce power losses,
albeit doing that fastens reaching MPP. It has been stated that this method is not suitable if the variation in
solar irradiation is high [26].
2.2. Incremental conductance method
This algorithm uses the fact that the voltage is zero at maximum power point (MPP) in panel power
slope. Unlike the previous method, the operating voltage is either decreased or increased and stop when
the MPP is reached. MPP tracking is restarted according to the change in panel current depending on
the surrounding conditions. Also, in this method, two sensors are required to get voltage and current values.
Same as in the previous algorithm, the size of the step is fixed [27].
2.3. Constant voltage method
This algorithm is not widely used due to some disadvantages. The relation is shown in (1) where
the maximum power point voltage VMPP is directly proportional to the open-circuit voltage VOC. VOC is
obtained experimentally, and VMPP is obtained by multiplying it with the solar cell constant KV, which is
about 0.76.
𝑉 𝑀𝑃𝑃 = 𝐾𝑣 𝑉𝑜𝑐 (1)
This algorithm is robust and simple, but it has disadvantages of losing power when the system disconnects
temporarily to measure the open-circuit voltage and calculate the operating voltage [28].
2.4. Short-current pulse method
This method has the same concept as in the constant voltage method. The MPP is obtained by
using (2). The MPP current IMPP is directly proportional to the short circuit current Isc. The constant KI is
roughly around 0.95. Therefore, the operating current is 95% of the experimentally obtained short-circuit
current. But in this method, determining the value of Isc is more difficult as it needs additional current sensor
and switch. Besides, obtaining its value from time to time increase heat dissipation and power losses [29].
IMPP = KIIsc (2)

2.5. Proposed method
The main idea is to use a boost converter for the MPPT with a controller circuit that contains
the PIC18F4550 microcontroller, which adjusts and control the duty cycle of the converter. PIC
microcontrollers are electronic circuits that can be modified to do a limitless scope of tasks. In this study,
the DC-DC boost converter circuit is simulated, as it is a more natural way to utilize the PV panel for power
supply adequately. A DC-DC converter is utilized to step up from 15 V to 60 V. The PV panel supplies
the 15 V input voltage, and the 60 V is the output voltage of the converter. The relationship of the generated
output voltage, duty cycle and the input voltage is explained in (3).

3. SYSTEM CONFIGURATION
The objective of the system is to develop an algorithm that increases the efficiency of the PV panels
in various conditions by using a boost converter. The proposed system's circuit is simulated in Proteus
environment. This system configuration is shown in Figure 2, comprises of an MPPT controller, solar panel,
load and DC-DC power converter. Figure 3 shows the system simulation. The input voltage supply provides a
voltage signal to the microcontroller. As a result, the DC-DC manages to boost the voltage from 15 Vdc to
60 Vdc. The PV output voltage fluctuates because of the changes in climate condition. Hence, the DC output
changes constantly. The microcontroller monitors the output of PV module, then provides the best power so
that PV panel delivers and keep adjusting until the maximum current value is obtained. The circuit involves
the voltage measurement signal to be used by the PIC18F4550 microcontroller. The changes of voltage are
suitable to be nourished into analog to digital converter (ADC) port of the PIC18F4550 microcontroller to
create a relative duty percentage of PWM signal reaction.

4. SIMULATION RESULTS AND DISCUSSION
For the DC to DC boost converter simulation, the input of 15 Vdc was supplied, and it was found out
that the output voltage at the load is overshoot until maximum 75 Vdc, then it dropped until 52 Vdc and then
fluctuated and remained constant at 58.62 Vdc after 23.420 ms, as shown in Figure 4. The magnification of
this output voltage can be seen in Figure 5. A voltage ripple of 0.438 V can be seen in the figure, which is equal
to 0.75% voltage ripple.
The output current flows through R4 reach steady state after 32.66 milliseconds is equal to 1.468 A,
as shown in Figure 6. The average current flowing through R4 is 1.4621 A, as shown in Figure 7. In terms of
the voltage in diode D1, it reaches a steady-state after 23.42 milliseconds with a magnitude of 59.45 V, as
shown in Figure 8.
The current flows through the Inductor L1 reached steady state after 31.074 milliseconds with
a maximum value of 5.9134 A as shown in Figure 9. The current in D1 reached steady state after
31.0748 milliseconds with a maximum value of 5.9134 A as illustrated in Figure 10. For the capacitor C3,
the current reaches steady state after 34.9748 milliseconds with a magnification equal to 4.461 A and 4.324 A
maximum and minimum are shown in Figure 11 and Figure 12, respectively.

Figure 13 shows the plotting of both the input and output voltage and current at the load. Figure 14
compares the output of the step-up converter to its input power. In the other part of the circuit for the 60 V
output, the output voltage at resistor R2 and capacitor C4 is shown in Figure 15 and Figure 16. The load current
in R2 is 1.778 A, which reaches steady state at 51.94 ms, as shown in Figure 17. The final plot
that compares the power when using this technique to normal situations is shown in Figure 18. With
MPPT, the system is able to achieve a maximum power of approximately 213.42 W as compared to 84 W
without MPPT.

5. CONCLUSION
In this work, the method of developing the MPPT algorithm for PV utilizing the Peripheral Interface
Controller has been successfully implemented with the integration of the DC-DC boost converter.
The developed control system adjusts the duty cycle of the converter to extract the maximum power.
With a DC input voltage of 15 V, the boost converter is capable of generating an output voltage of an
approximately 60 Vdc at a maximum power of 213.42 W with minimum voltage ripple as compared to 84 W
without the MPPT. This proved the effectiveness and adequacy of the developed algorithm.
