چکیده
Wind power is one of the optimistic sources of energy generation among all the renewable energy sources. Hence for exploiting wind energy sources it must be connected to electric grid. Wind power inculation into grid affects power quality because of its fluctuating nature. This paper recommends a control scheme based on instantaneous SRF (Synchronous Reference Frame) theory for compensating the reactive power requirement of a three phase grid connected wind energy generating system along with the mitigation of harmonics produced by non linear load connected at PCC using STATCOM. In this proposed scheme a STATCOM (static synchronous compensator) is connected at a point of common coupling with a battery energy storage system (BESS) to mitigate the power quality problems is simulated using MATLAB/SIMULINK in simpower system block set.. Fuzzy based controller is designed to improve the profile of source current in STATCOM.
