The document discusses the components and advantages of smart grids. It explains that smart grids use digital technology to monitor, control and analyze the electricity supply chain. This allows for more reliable delivery of power from various distributed sources like solar and wind. Key smart grid technologies include intelligent appliances, smart meters, super conducting cables, phasor measurement units, and smart substations. The smart grid provides benefits like better power management, supply/demand management, and remote meter reading. However, security and grid volatility are disadvantages if the network is not developed properly. Overall, smart grids have revolutionized the energy system through increased reliability, efficiency and consumer access.
One promising means of reducing the transmission and distribution losses is through the distributed generation of electricity closer to the end user such as net metering schemes. And the other approach is managing customer consumption of electricity in response to supply conditions, for example, stimulating electricity customers to reduce their consumption at critical times or in response to market prices, thereby reducing the peak demand for electricity. In order to assist consumers to make informed decisions on how to manage and control their electricity consumption, consumers should have a system to monitor their real-time electricity consumption as well as a communication network with the service provider. But traditional electricity meters only record energy consumption progressively over time, normally in monthly basis and provide no information of when the energy was consumed. Therefore the necessity of Advanced Metering Infrastructure (AMI) has been emerged to address the above matters. Nowadays most of the nations are looking to rollout into Smart Meters enabling faster automated communication of information to consumers on their real time electricity consumption, and to service providers.
a smart meter electronically measures how much energy is being used and how much it costs, and then communicates it to the energy supplier and the customer. Smart meters can also enable the provision of new services to consumers as it can record consumption of electric energy in intervals of an hour or less, and also gather data for remote reporting using two-way communication between the meter and central system.

It defines intelligent electrical systems as IT-enabled networks that provide real-time operational efficiency through components like self-healing networks, dynamic network models, and business integration frameworks. These systems establish interconnected network models from transmission to consumption and enable functions like automated fault detection and restoration. The technologies discussed support reliability improvements, asset optimization, and customer participation. Intelligent electrical systems provide utilities preliminary smart grid capabilities and a path toward more advanced solutions.

Paper Title
Particle Swarm Optimization–Long Short-Term Memory based Channel Estimation with Hybrid Beam Forming Power Transfer in WSN-IoT Applications

Abstract
Non-Orthogonal Multiple Access (NOMA) helps to overcome various difficulties in future technology wireless communications. NOMA, when utilized with millimeter wave multiple-input multiple-output (MIMO) systems, channel estimation becomes extremely difficult. For reaping the benefits of the NOMA and mm-Wave combination, effective channel estimation is required. In this paper, we propose an enhanced particle swarm optimization based long short-term memory estimator network (PSOLSTMEstNet), which is a neural network model that can be employed to forecast the bandwidth required in the mm-Wave MIMO network. The prime advantage of the LSTM is that it has the capability of dynamically adapting to the functioning pattern of fluctuating channel state. The LSTM stage with adaptive coding and modulation enhances the BER.PSO algorithm is employed to optimize input weights of LSTM network. The modified algorithm splits the power by channel condition of every single user. Participants will be first sorted into distinct groups depending upon respective channel conditions, using a hybrid beamforming approach. The network characteristics are fine-estimated using PSO-LSTMEstNet after a rough approximation of channels parameters derived from the received data.

3. Components Of Smart Grid
For the generation level of the power system, smart enhancements will extend from the
technologies used to improve the stability and reliability of the generation to intelligent
controls and the generation mix consisting of renewable resources.
Components of Smart Grid are:
1. Monitoring and Control Technology Component
2. Transmission Subsystem Component
3. Smart Devices Interface Component
4. Intelligent Grid Distribution Subsystem Component
5. Storage Component
6. Demand Side Management Component
4. Monitoring and Control Technology Component
• In a conventional power system, electricity is distributed from the power plants through the
transmission and distribution networks to final consumers. Transmission and distribution
networks are designed to deliver the electricity at the consumer side at a predefined voltage
level. Photovoltaic power generation is in general connected at the distribution level of the
power system.
• For this reason, it is possible for the power produced by the PV to cause a 'counter' power
flow from the consumer side to be delivered to other consumers through the distribution
network.
• This phenomenon may present two challenges: an increase of the voltage in areas with high
PV production; and voltage fluctuation throughout the system due to the intermittency
characteristics of the PV production.
• Intelligent transmission systems include a smart intelligent network, self-monitoring and
self-healing, and the adaptability and predictability of generation and demand robust
enough to handle congestion, instability, and reliability issues.
5. Fig: Distribution and automation system for electric power companies
• This new resilient grid has to
resist shock (durability and
reliability), and be reliable to
provide real-time changes in its
use. Taking these issues into
consideration, voltage control
systems that incorporate
optimal power flow
computation software are
developed.
• These systems have been
designed to rapidly analyze
power flow to forecast the
voltage profile on the
distribution network, and, in
some cases, control voltage
regulation equipment to ensure
the appropriate voltage.
6. Transmission Subsystem Component
• The transmission system that interconnects all major substation and load centers is
the backbone of an integrated power system. Transmission lines must endure
dynamic changes in load and emergency without service interruptions. Strategies to
achieve smart grid performance at the transmission level include the design of
analytical tools and advanced technology with intelligence for performance analysis
such as dynamic optimal power flow, robust state estimation, real-time stability
assessment, and reliability and market simulation tools.
• Real–time monitoring based on PMU, state estimators sensors, and communication
technologies are the transmission subsystem’s intelligent enabling tools for
developing smart transmission functionality.
7. Smart Devices Interface Component
• Smart devices for monitoring and control form part of the generation components’ real time
information processes. These resources need to be seamlessly integrated in the operation of both
centrally distributed and district energy systems.
• Apart from a physical model of a smart device, there is also a need for a logical model for a
smart device. Such a model must outline what a smart device offers to a smart space with regards
to the services it can provide to the environment.
• The model must also outline interactions between smart devices, changes in the state of smart
device operation, and smart services within a smart space. There are various models present
today that have similar approaches to modeling device.
• Two such models would include Home Plug and Play (HPnP), which is slightly out of date but
still applicable, and the newer Universal Plug and Play (UPnP), which is an open standards body.
These two standards bodies have modeled devices by the services that they offer and have also
developed interaction models for device communication.
• Another emerging standard for defining services in an abstract way is with the use of the Web
Services Definition Language (WSDL). Along with describing services a smart device can
provide, there must also be a way of representing changes in states of smart devices and how de-
vices react to these changes within a smart environment.
8. Intelligent Grid Distribution Subsystem Component
• The distribution system is the final stage in the transmission of power to end users. At the
distribution level, intelligent support schemes will have monitoring capabilities for
automation using smart meters, communication links between consumers and utility
control, energy management components, and AMI.
• The automation function will be equipped with self - learning capability, including
modules for fault detection, voltage optimization and load transfer, automatic billing,
restoration and feeder reconfiguration, and real–time pricing. Electric companies are
accelerating efforts to develop an advanced meter infrastructure (AMI) to improve
customer services and reduce meter reading costs.
• An essential element in this AMI is the smart meter. A smart meter is a device that not only
measures the electricity consumption but is also able to communicate with a center.
Developing the communication network between the meter and the center present several
challenges, including costs and reliability.
9. • AMI technologies and systems need to be developed to ensure reliability and flexibility
in measuring and controlling electricity meters through next generation wireless mesh
networks. Wireless mesh networks provide a transmission method that links electric
meters to relay data by each meter through other meters, using a multi-hop network
scheme.
• This network is helpful reduce the time required to acquire data while at the same time
curtailing costs. While wireless mesh networks present cost benefits, some challenges
have to be overcome to ensure practical application. Simultaneous transfer of data
between meters at the same frequency can cause signal collision, preventing reliable
data collection.

days for electric power
companies.
11. Due to the unpredictability of renewable energy and the disjoint between peak
availability and peak consumption, it is important to find ways to store the generated
energy for later on use. Options for energy storage technologies include pumped
hydro, advance batteries, flow batteries, compressed air, super-conducting magnetic
energy storage, super-capacitors, and flywheels. Associated market mechanism for
handling renewable energy resources, distributed generation, environmental impact
and pollution has to be introduced in the design of smart grid component at the
generation level.
Storage Component
12. Demand Side Management Component
• Demand Side Management (DSM) and energy efficiency options developed for effective
means of modifying the customer demand to cut operating expenses from expensive
generators and suspend capacity addition. DSM options provide reduced emissions in fuel
production, lower costs, and contribute to reliability of generation.
• These options have an overall impact on the utility load curve. Electric power companies
are obligated to maintain constant frequency levels and the instantaneous balance between
demand and supply by adjusting output through the use of thermoelectric and pumped
storage generation. With the expected increase in photovoltaic power generation the supply
power may fluctuate considerably due to changes in the weather.
• Imbalance between demand and supply cause fluctuation in the system frequency, that
may, in turn, affect negatively user appliances and, in a worst case, lead to a power outage.
In order to resolve this issue, optimal demand-supply control technologies are re-quired to
develop to control not only conventional generators but also batteries and other storage
devices.

demand and supply planning and
control system for electric power
companies and transmission
system operators.
14. Technologies of Smart Grid
Smart Grids is a new concept for electricity networks. The initiative responds to the rising
challenges and opportunities, bringing benefits to all users, stakeholders and companies that
perform efficiently and effectively. Smart Grid Technologies are already used in other
applications such as manufacturing and telecommunications and are being used in grid
operation.
Department of Energy (DOE) lists five fundamental technologies that will drive the Smart
Grid
• Integrated communications, connecting electronic components to get information and
control every part in real time, on the other hand, make every part of the Smart Grid both
‘listen’ and ‘talk’.
15. • Sensing and measurement technologies, to provide faster and more accurate response
information of each important part of Smart Grid, such as remote monitoring, real time
thermal rating, electromagnetic signature analysis, real-time pricing and demand-side
management.
• Advanced components, to apply the latest research in superconductivity, storage, power
electronics and diagnostics. they include: flexible alternating current transmission system
devices, high voltage direct current, first and second generation superconducting wire, high
temperature superconducting cable, distributed energy generation and storage devices,
composite conductors, and “intelligent” appliances.
• Advanced control methods, to monitor essential components, enabling rapid diagnosis and
precise solutions appropriate to any event. There are three categories for advanced control
methods: distributed intelligent agents, analytical tools, and operational application.
• Improved interfaces and decision support, information systems reduce the complexity of
Smart Grid to make both operator and manager use it more efficiently and easily, to amplify
human decision-making.
