Simulation of Improvement of Power Quality Using Statcom-control Scheme with Grid Connected Wind Energy System

Abstract

The use of wind energy generation in electrical grid is increasing worldwide. Injection of the wind power into an electric grid affects the power quality. The generated wind power is always not constant due to its time varying nature and causing stability problems. This weak interconnection of wind generating source in the electrical network affects the power quality and reliability. In this paper the power quality problem due to installation of wind turbine with the grid is determine. In this proposed scheme Static Compensator (STATCOM) is connected at a point of common coupling to reduce the power quality problems. The STATCOM gives reactive power support to wind generator and also load. The proposed system maintains the grid voltage free from distortion and harmonics.In this paper the effect of STATCOM is presented
