摘要:This paper proposes a modified control strategy for unified Power Quality conditioner to alleviate voltage and current abnormalities in three phase system. Renewable source integration and nonlinear loads depreciates Power Quality of the system. Active Power Filters play a paramount role in alleviating PQ disturbances. To deal with current imperfections and reactive power compensation, modified dq controller is proposed for shunt controller. ANFIS-dq control strategy is proposed for Series Controller to suppress voltage imperfections Photovoltaic unit is optimally connected at DC link of UPQC for supporting controlling action and to deliver real power Proposed optimal renewable source integrated UPQC performance is studied with traditional PI and ANFIS controller. MATLAB / SIMULINK platform is used for analyzing proposed system performance.
