The Unified Power Quality Conditioner (UPQC) has the capability of improving power quality in the industrial distribution systems. It is a combination of shunt and series active power filters, both joined together by a common Direct current (DC) bus. The major issue when utilizing the UPQC is the determination of the optimal parameters. The traditional method used to determine the optimal parameters of the UPQC is a daunting task, because the system requires greater computational and simulation efforts. This paper proposes a faster approach using the concept of a Membership Function (MF) in which a Weight Factor (WF) is utilized. In the proposed technique, a range of values is specified for each parameter of the filters. These values are used to design a membership function for each parameter, and the choice of the optimal parameter is extracted by the aid of a WF. In this study, the effectiveness of the UPQC was tested at various system conditions to verify the performance of the proposed technique. The presented results show that the obtained parameters of UPQC using the proposed technique can provide fast dynamic response.
