A STATCOM-Control Scheme for Grid Connected Wind Energy System for Power Quality Improvement using PI Controller

The grid-connecting wind energy generation system for power quality improvement by using STATCOM-control scheme is simulated with the help of MATLAB When the wind power is connected to an electric grid affects the power quality. The effects of connecting wind turbine into the grid system covers power quality areas are the active power, reactive power, harmonics and variation of voltage, and electrical performance of switching operations. The installation of wind system with the grid creates the power quality problems which can be determined by studying this paper. By using the Static Compensator (STATCOM) with using. battery energy storage system (BESS) at the point of common coupling to improving the power quality of the grid The battery energy storage used to keep real power from varying wind power. At lower power demand hours the generated power can be stowed in the batteries. The combination of battery storage with wind energy generation system will even out the grid system by absorbing or injecting reactive power and enable the real power flow essential to the load. This recreates the main supply source from the reactive power demand of the load and induction generator in this proposed scheme.
