ABSTRACT
To have sustainable growth and social progress ,it is necessary to meet the energy need by utilizing the renewable energy resources like wind,hydro,biomass etc… The injection of the wind power into an electric grid affects the power quality.The performance of the wind turbine and thereby power quality are determined on the basis of measurements and norms followed according to guideline specified in IEC-61400.This demonstrates power quality problem due to installation of wind turbine with the grid.
In this proposed scheme STATic COMpensator (STATCOM) is connected at a point of common coupling with a battery energy storage system(BESS) to mitigate the power quality issues.The battery energy storage is integrated to sustain the real power source under fluctuating wind power.The STATCOM control scheme for the grid connected wind energy generation system for power quality improvement is simulated using MATLAB/SIMULINK in power system block set.The effectiveness of the proposed scheme relieves main supply source from the reactive power demand of load and induction generator.
