Power Quality Improvement and Mitigation of Harmonics for Grid Integrated Wind Energy System Using STATCOM

Wind power is one of the optimistic source of energy generation among all the renewable energy sources. Hence for effectively exploiting wind energy sources it must be connected to electric grid. Wind power inculation into grid affects power quality because of its fluctuating nature. The concerned power quality issues are voltage sag, voltage swell, active power, flicker, reactive power, harmonics, voltage interruption and power quality depends upon performance of switching devices. This paper recommends a control scheme based on instantaneous SRF theory for compensating the reactive power requirement of a three phase grid connected wind energy generating system along with mitigation of harmonics produced by non linear load connected at PCC using STATCOM. To overcome the power quality issues of grid connected wind energy generating system, the STATCOM control scheme with non linear load is simulated using MATLAB/SIMULINK. The results of this sustainable and renewable model are to meet the power demand and for promoting green energy systems.
