In order to keep power quality under the limits proposed by standards, it is required to incorporate some sort of compensation. There are two basic types of PFC circuits: active and passive. The simplest power factor correctors can be implemented using a passive filter to suppress the harmonics in conjunction with capacitors or inductors to generate or consume the fundamental reactive power, respectively. Active power factor correction circuits have proven to be more effective, generally integrated with the switch-mode circuitry, and actively control the input current of the load. This enables the most efficient delivery of electrical power from the power grid to the load. The demand for new smart, green products has set the stage for a worldwide migration from antiquated passive circuits to active correctors as well as from traditional analog technology to digital techniques. New digital active power factor correction delivers better full- and light-load power efficiency while lowering system costs, enabling smaller designs and providing a clear path for further feature enhancements and improved competitive positioning for a whole host of consumer and industrial products. Cirrus Logic’s novel advances in digital active PFC technology signify a major enabling element in the development of the newest generation of low cost, energy-efficient switch mode products.

Power Quality Improvement in Power System using UPFCijtsrd
Occurrence of a fault in a power system causes transients. To stabilize the system, Power System Stabilizer (PSS) and Automatic Voltage Regulator (AVR) are used. Load flow analysis is done to analyze the transients introduced in the system due to the occurrence of faults. The Flexible Alternating Current Transmission (FACTS) devices such as UPFC are becoming important in suppressing power system oscillations and improving system damping. The UPFC is a solid-state device, which can be used to control the active and reactive power. This paper considers a power system as a case study for investigating the performance of UPFC is achieving stability. By using a UPFC the oscillation introduced by the faults, the voltage deviations and speed deviations can be damped out quickly than a system without a UPFC. The effectiveness of UPFC in suppressing power system oscillation is investigated by analyzing their voltage deviations and reactive power support in this paper. A proportional integral (PI) controller has been employed for the UPFC. It is also shown that a UPFC can control independently the real and reactive power flow in a transmission line.

Abstract: The flexible Ac transmission system (FACTS) controllers can play an important role in the power system security enhancement. However, due to high capital investment, it is necessary to locate these controllers optimally in the power system. FACTS devices can regulate the active and reactive power control as well as adaptive to voltage-magnitude control simultaneously because of their flexibility and fast control characteristics. Placement of these devices in suitable location can lead to control in line flow and maintain bus voltages in desired level and so improve voltage stability margins. In the previous paper three type of FACTS devices used in transmission lines for improvement of voltage profile in the power system. This paper describes the simulation result of flexible Alternative Current Transmission Systems (FACTS) devices used in the disturbed power systems. Out of three types of FACTS device UPFC performances is considered to be best comparatively with respect to each of the three devices.

The document proposes an artificial bee colony (ABC) algorithm based neuro fuzzy controller (NFC) to improve the performance of a unified power quality conditioner (UPQC) in compensating for power quality issues like voltage sags. The NFC uses the error and change in error voltage as inputs to a neural network. The ABC algorithm is used to optimize the neural network output. This optimized output is then used to generate optimal fuzzy rules and calculate the discharging capacitor voltage from a bias voltage generator, replacing the DC link capacitor. Simulation results show the proposed ABC-NFC method performs better than ANFIS, ANN, FLC and NFC in compensating for voltage sags.

Adaptive Fuzzy PID Based Control Strategy For 3Phase 4Wire Shunt Active Filte...IJERA Editor
The document presents a new control strategy for controlling a shunt active power filter to compensate for reactive power and reduce current harmonics in a grid connected to a renewable energy based distribution system. The proposed control strategy uses a fuzzy PID controller to determine the reference compensating currents for a three-phase shunt active power filter. Simulations in MATLAB/Simulink show that the controller has fast dynamic response, accurately tracks the DC voltage reference, and is robust to load parameter variations. The fuzzy PID controller hybridizes classical PID and fuzzy control to exploit the benefits of both.

A review on SVC control for power system stability with and without auxiliary...journalBEEI
Since the beginning of the last century, power system stability has been recognized as a vital problem in securing system operation. Power system instability has caused many major blackouts. This paper reviewed the previous technical works consisting of various methods of optimization in controlling power system stability. The techniques presented were compared to optimize the control variables for optimization of power system stability. Power system stability enhancement has been investigated widely in literature using different ways. This paper is focusing on SVC performance for enhancing power system stability either through SVC controlled itself or SVC controlled externally by other controllers. Static VAR compensators (SVCs) are used primarily in power system for voltage control as either an end in itself or a means of achieving other objectives, such as system stabilization.The analysis on performance of the previous work such as advantages and findings of a robust method approach in each technique was included in this paper.
The power quality issue will take new dimension due to power system restructuring and shifting trend towards
distributed generation. Huge loss in terms of time and money has made power quality problems a major anxiety for modern
industries with non-linear loads in electrical power system. Power quality consists of a large number of disturbances such
as voltage sags, swells, harmonics, notch, flicker, etc. Power quality problems can be mitigated by many methods but most
appropriate solution to mitigate these problems is FACTS devices. In this paper a brief survey of FACTS devices are
presented which are used to mitigate power quality problems.

Sri Guru Hargobind Ji - Bandi Chor Guru.pdfBalvir Singh
Sri Guru Hargobind Ji (19 June 1595 - 3 March 1644) is revered as the Sixth Nanak.
• On 25 May 1606 Guru Arjan nominated his son Sri Hargobind Ji as his successor. Shortly
afterwards, Guru Arjan was arrested, tortured and killed by order of the Mogul Emperor
Jahangir.
• Guru Hargobind's succession ceremony took place on 24 June 1606. He was barely
eleven years old when he became 6th Guru.
• As ordered by Guru Arjan Dev Ji, he put on two swords, one indicated his spiritual
authority (PIRI) and the other, his temporal authority (MIRI). He thus for the first time
initiated military tradition in the Sikh faith to resist religious persecution, protect
people’s freedom and independence to practice religion by choice. He transformed
Sikhs to be Saints and Soldier.
• He had a long tenure as Guru, lasting 37 years, 9 months and 3 days

based on the concept of combined series-shunt FACTS Controller.
It has the ability to simultaneously control all the transmission parameters
affecting the power flow of a transmission line i.e. voltage, line impedance
and phase angle.
By controlling impedance, voltage magnitude, phase angle, UPFC is used to
control the power flow in the transmission systems.

7. Why an UPFC?
There are frequent disturbances in a power system due to its dynamic nature
and it can lead the system to an unsteady condition.
We can increase transmission system reliability and availability by
using UPFC, also it increase dynamic and transient grid stability of
the system.
With the increasing demand, the existing transmission network should be
used optimally rather than constructing new transmission lines.
UPFC provide better utilization of existing transmission system
assets and environmental benefits.

The Shunt and series voltage inverters are connected through a DC link capacitor to coordinate . This will
allow bidirectional flow of real power in the middle of output terminals of shunt and series inverters. The
energy storing capacity of the DC capacitor is generally low. Therefore the real power demand of the series
inverter has to be supplied by the shunt inverter.
Different PI controllers are used to control the operation of the UPFC including decoupling PI controllers,
hybrid PI controllers, and cross-coupling PI controllers. The real and reactive power flows decrease when
cross-coupling PI controllers are used and the direct coupling PI regulation methods can lessen the harmonics
in the measurement. For the purpose of damping oscillations in power systems, a mixture of cross-coupling PI
controller and direct coupling controllers, known as hybrid controllers, were recommended.
