Power Quality Enhancement of Grid Connected Wind Energy System Using Static Synchronous Compensator

Due to increased power demand and environmental concern, wind power generation is rapidly growing and wind plants are being integrated to power networks worldwide in large numbers. Injection of wind power into a utility grid results in violation of power quality due to the fluctuating nature of the wind. According to IEC standard, determination of power quality is from the performance of wind generators. In this work power quality issues such as voltage variations, flickers, harmonics are demonstrated due to installation of wind turbine with the grid. FACTS devices can be used to overcome these power quality problems. This paper proposes the STATCOM control scheme for grid connected wind energy system for power quality enhancement. The simulation has been done in MATLAB/Simulink block set. It is shown that STATCOM enhances the power quality of power grid consisting induction generator based wind plant
