Abstract—In this paper the grid interconnection issues of AC-DC-AC inverter interfaced wind energy conversion system have been dealt. The power flow in context of load has now reversed in such local generating stations; the voltage rise at the point of common coupling (PCC) in the case of large scale wind farm is well known. The wind energy conversion system has to be taken out if the voltage exceeds beyond limit. Thus the capacity factor of the wind farm may be poor. In this case, the grid inverter can support the voltage at PCC by injecting reactive power along with the active power. The simulation results are given here for improving the voltage at PCC.

Index Terms—Point of Common Coupling (PCC), Permanent Magnet Synchronous Generator (PMSG), WindEnergy, Grid Interconnection, Electric Power System(EPS).
