During this paper Modelling and Control of Three and Four Leg Inverter in Wind Energy System for Grid Power Quality Improvement. Static Compensator (STATCOM) is connected at a point of common coupling with a battery energy storage system (BESS) to resolve the power quality difficulties. The battery energy storage utilized to preserve constant real power from varied wind generation. The generated power is often keep within the batteries at low power demand hours. The grouping of battery storage with wind energy generation system can mix the output by fascinating or inserting reactive power and allow the real power flow needed by the load. In the grid new renewable resources is supplemental to extract more power. Injection of wind generation into the grid affects the quality of power resulting in poor performance of the system. Wind energy is taken in to account to be a really promising various for power generation as a result of its various for power generation as a result of its tremendous environmental, social, and economic benefits. In general voltage & frequency should be kept as stable as possible. This stability are often obtained by utilizing the FACTS devices. Recently VSI or CSI based various FACTS devices have been used for flexible power flow control, secure loading and damping of power system oscillation. The FACTS Device (STATCOM) control scheme for the grid connected wind energy generation system to improve the power quality is simulated by using MATLAB/SIMULINK.
