Abstract
In this paper, we present an analysis and simulation of a PV interactive shunt power active filter. This system is used to eliminate harmonics generated by a nonlinear load and reactive power compensation. 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 provides reactive power compensation and filter harmonic currents. For the Shunt Active Filter reference current computation. We used the synchronous d-q-o reference frame algorithm (SRF) and for gating signal generation we apply the carrier-based PWM modulation. 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.
