A Svc Light Based Technique for Power Quality Improvement for Grid Connected Wind Energy System

Abstract

The power produced from wind energy source is always fluctuating due to variation in the wind. Connecting this wind sources to grids leads the system to issues , and shows the impact on the functionality of the grid to be impaired. Thus wind power injection in to an electric grid affects the quality of power.. This project deals the existence of the power quality problems due to the installation of wind turbine with grid. In order to eliminate these power quality problems, this project proposes a scheme based on FACTS device called SVC light which is connected at a Point of Common Coupling. The proposed model is compared with the model that do not use any compensating device .Performance of the system with BESS under load variations and Fault ride through capability of the svc light is also analysed. This control scheme for the grid connected wind energy generation system is to improve the power quality and this system is simulated using MATLAB /SIMULINK in power system block set.
