A Novel Hybrid Energy Source Based Unified Power Quality Conditioner with Effective Coordinate control

Abstract

This study presents a combined operation of the Unified Power Quality Conditioner (UPQC) with Photo voltaic & wind energy based hybrid system. The proposed system consists of a series inverter, a shunt inverter and a battery connected Photovoltaic array which is connected with the DC link of UPQC through a boost converter. The proposed system compensates the voltage sag, voltage swell, voltage interruption, harmonics, real and reactive power compensation. PV fed UPQC system with and without UPQC is simulated. The proposed system is validated with the results of computer simulation using Matlab-Simulink software. Sag is created by applying heavy load and swell occurs during light load conditions. These power quality problems are compensated with the help of UPQC fed Photovoltaic arrays.
