Abstract – The paper presents rapid growth of wind power systems worldwide will likely see the integration of large wind farms with electrical network that are series compensated stable transmission of bulk power. This paper presents an UPQC control and independent operation of the rotor-side converter (RSC) and grid-side converter (GSC) for a doubly fed induction generator (DFIG)-based wind energy conversion system under unbalanced grid voltage conditions .The proposed method can make the RSC and GSC available to an independent operation with a simple implementation for higher reliability with UPQC control. Four-wire Unified Power Quality (UPQC) to improve power quality of wind energy conversion system (WECS). The UPQC is realized by the integration of series and shunt active power filters (APF) sharing a common dc bus capacitor the experimental results demonstrate the effectiveness of the proposed control strategy for both the RSC and GSC under unbalanced grid voltage conditions. MATLAB simulation result shows proposed system improves stability considerably.
