Power quality can be defined as any power quality problems manifested in voltage, current and frequency those results in failure or mal-operation of customer equipment. Injection of wind power into an electric grid affects the power quality. The work analyses the performance of Static Compensator (STATCOM) with a wind energy generating system at the point of common coupling to mitigate the power quality issues. During the Normal Operation, wind turbine produces a continuous variable output

... . The main Power quality issues are voltage sag, swell, flickers, harmonics etc. The design of a Fuzzy logic controller using voltage as feedback for significantly improving the dynamic performance of converter. The performance is analysed with the help of PI controller and Fuzzy logic technique. The simulation studies have demonstrated the effective influence of the STATCOM on the improvement of the voltage using MATLAB/Simulink and make the wind turbine generator to be in service even under fault conditions. It also shows that fuzzy logic controller gives better result as compared to PI controller.
