Abstract

With the increasing of nonlinear loads in household application which may cause power quality issues at distribution end. In this paper, an analysis and simulation of a PV interactive shunt power active filter (SPAF) in single phase circuit. This system is used to eliminate harmonics generated by a nonlinear load. In the day-time with intensive sunlight, the PV interactive Shunt Active Filter system brings all its functions into operation. At night and during no sunlight periods, the power required by the loads is received from the distribution system while the inverter system only providesreactive power andfilter harmonic currents. For the Shunt Active Filter reference current computation. We used the instantaneous real and reactive current (Ip-Iq) algorithm and for gating signal generation we apply the hysteresis current control technique. The Simulation results (using MATLAB/SIMULINK) are presented and discussed. They show the effectiveness of the photovoltaic compensation system, the sinusoidal form of the current and the effectiveness of the reactive power compensation. The proposed solution has achieved a low THD (Total Harmonic Distortion), demonstrating the effectiveness of the presented method.
