Photovoltaic unified power quality conditioner sag and interruption mitigation

Abstract: This paper proposes a new configuration of photovoltaic unified power quality conditioner (PV-UPQC) that consists of the PV array, DC/DC converter and UPQC for compensating the voltage interruption. The proposed PV-UPQC can compensate the reactive power, harmonic current, voltage sag and swell and the voltage interruption. The performance of the proposed system is verified through …
