Power Quality of Grid Connected Distributed Generation System: Role of FACTS Device

Abstract: This paper demonstrated of power quality problems associated with the wind turbine based distributed generation systems and how the FACTS device such as UPFC play an important role in power quality improvement of Distributed Generation System. The purpose of the paper is to derive and analyze a reactive power control strategy of UPFC dedicated for DFIG mitigation. The FACT device Unified Power Flow Controller (UPFC) is connected with load bus. Matlab/simulink is used for the work. Paper demonstrated the simulation results for with and without UPFC for Grid connected distributed generation system.
