Abstract

Renewable energy sources (Res) are being connected to an electrical system using electronic power devices. The use of these devices generates harmonic currents and degrades the quality of energy. This article presents the study of the integration of photovoltaic systems in the electrical grid (low voltage) with and without the presence of a nonlinear (three-phase rectifier PD3). In this paper, we use the MPPT controller for Boost converter, and the PWM control for the three-phase
inverter that ensure the connection. The simulation results obtained without the nonlinear load show that the waveforms of the currents propagated in the PV system or in the electrical grid are very close to the sinusoid, and the values of the total harmonic distortion (THD) rates are in the standard used. On the other hand, the presence of the non linear charge degrades the waveforms of the currents and gives us THD values higher than the norm.
