Description: Large number of wind turbines are being installed
and connected to power systems. The penetration level of wind
power is continuously increasing in some networks, the
significant high penetration may affect the power system security
if the wind generators can not recover to normal operation
immediately after a temporary disturbance. This paper studies
the effect of power electronic system on stability improvement of
a wind turbine system. The functions of the STATCOM and
DVR in improving the system stability have been demonstrated.-Large number of wind turbines are being installed

Description: In this paper, the performance of voltage-source
converter-based shunt and series compensators used for load
voltage control in electrical power distribution systems has been
analyzed and compared, when a nonlinear load is connected
across the load bus. The comparison has been made based on
the closed-loop frequency response characteristics of the compensated
distribution system. A distribution static compensator
(DSTATCOM) as a shunt device and a dynamic voltage restorer
(DVR) as a series device are considered in the voltage-control
mode for the comparison.

Description: Modern electric power systems are complex networks with hundreds of generating stations and thousands of load centers are interconnected through long power transmission and distribution networks. Power quality is major concern in industries today because of enormous losses in energy and money. With the advent of myriad sophisticated electrical and electronic equipment, such as computers, programmable logic controllers and variable speed drives which are very sensitive to disturbances and non-linear loads at distribution systems produces many power quality problems like voltage sags, swells and harmonics and the purity of sine waveform is lost. Voltage sags are considered to be one of the most severe disturbances to the industrial equipments.

Description: This project deals with modeling and simulation technique of a Dynamic Voltage Restore (DVR).The DVR is a dynamic solution for protection of critical loads from voltage sags / swells. The DVR restores constant load voltage and voltage wave form by injecting an appropriate voltage. Present novel structure improves power quality by
compensating voltage sag and voltage swells.
The transient response of any natural system is the way in which the response of the system behaves as a function of time. Electromagnetic transient studies have always played an essential behavior of the system in the event of different forms of transient phenomena, which can hardly be achieved by other means. This project addresses the transient studies of electrical networks with embedded, power electronics-based, FACTS and Custom Power (CP) controllers. -This project deals with modeling and simulation technique of a Dynamic Voltage Restore (DVR).The DVR is a dynamic solution for protection of critical loads from voltage sags / swells.

Description: This paper describes the problem of voltage sags and swells and its severe impact on non linear loads or
sensitive loads. The dynamic voltage restorer (DVR) has become popular as a cost effective solution for the
protection of sensitive loads voltage sags and swells. The control of the compensation voltages in
DVR based on dqo algorithm is discussed. It first analyzes the power circuit of a DVR system in order to
come up with appropriate control limitations and control targets for the compensation voltage control. The
proposed control scheme is simple to design. Simulation results carried out by Matlab/Simulink verify the
performance of the proposed method.-This paper describes the problem of voltage sags and swells and its severe impact on non linear loads or
