Abstract

The Now a day’s power quality (PQ) issue is one of the main technical challenges in any power system. In order to provide improved PQ of energy supply, it is necessary to analyze the harmonics distortion of the system as well as the voltage sag and swell. This paper proposes a combined photovoltaic (PV) and unified power quality conditioner (UPQC) for compensation of source voltage deficiencies basically sag and reduction of harmonics in source current. “The UPQC has been extensively useful and it is verified to be the best solution to diminish this PQ issue.” However, the operation of UPQC is also depends upon the DC-link voltage value. Likewise, if the DC-link voltage is not constant, it its performance will decrease. This paper explore the detail of PQ impacts in PV connected UPQC system for improving the performance in terms of harmonics mitigation and voltage sag compensation. “The proposed model is developed in MATLAB/SIMULINKR and the result obtained validates the superiority of proposed technique over others in terms of harmonics elimination and sag compensation.
