Power Quality Improvement of Grid Connected Wind Energy System

In this paper a control scheme for Battery Energy Storage System-Static Compensator is connected at a point of common coupling to mitigate the power quality issues. The STATCOM control scheme for the grid connected wind energy generation system for power quality improvement will be simulated using MATLAB/SIMULINK in power system block set.Amarked reduction in the Total Harmonic Distortion is observedin source current of Wind Energy Generation System (WEGS) with the incorporation ofthis scheme.The development of the grid co-ordinationrule and the scheme for improvement in power quality norms asper IEC-standard on the grid has been presented.The influence of wind turbine in grid system concerning power quality measurements are active power, reactive power, variation of voltage, flicker, harmonics, and electrical behaviour of switchingoperation.. When Wind Energy is integrated with grid, the issue of power quality arises. Awareness of power quality is highly increased in a sensitive industry
