Abstract: By means of the increase in demand for electricity due to increase in population industrialization, the generation of power is really a challenge now a days. It is essential to meet the energy needs by utilizing the renewable energy resources like wind, biomass, hydro co-generation, etc. Addition of the wind power into an electric grid affects the power quality. The major power quality issues are voltage sag, swell, flickers, harmonics etc. During this future scheme Static Compensator (STATCOM) is linked at the point of common coupling with a battery energy storage system to mitigate the power quality issues. The battery energy storage is integrated to sustain the real power source under fluctuating wind power. Here three control schemes for STATCOM are compared PI controller, fuzzy logic controller and Hybrid controller. The process of the three STATCOM control schemes for maintaining the power quality of the grid connected wind energy system is investigated using MATLAB/SIMULINK.
