Abstract
This chapter is focused on the improvement of the grid current quality at the Point of Common Coupling (PCC) of a Single-Phase Grid-Connected Photovoltaic System (GCPVS) supplying the nonlinear load. Thus, with the implementation of a specific control strategy applied to the PV inverter which is used essentially to inject the solar power into the grid, the compensation of the disturbing current introduced by the nonlinear load can be performed. Furthermore, the efficiency of this control strategy is related to an algorithm aimed to extract the correct disturbing currents and to the performance of the used current controllers. Consequently, two methods of control strategy of the PV inverter are investigated and compared in this chapter. The first method comes from those found in the bibliography and the second is original due to use simple PI controllers. The effectiveness of each control strategy is verified by simulation using Matlab/Simulink and validated experimentally through an experimental platform. Therefore, basing on simulation and experimental results, the comparative study shows better performances of the second proposed methods.
