Abstract: This paper proposes a new configuration of PV-UPQC (Photovoltaic Unified Power Quality Conditioner) that consists of the Photovoltaic array, DC/DC converter and UPQC for compensating the voltage interruption. The proposed PV-UPQC can compensate the voltage sag and the voltage interruption. The performance of proposed system was verified through simulation. The proposed system can improve the power quality at the common connection point of the non-linear load the sensitive load and voltage interruption.
