A PID-Fuzzy Based Controller for Three-Phase Solar Network

Abstract

In this study, by considering the importance of the Renewable Energy Sources applications, especially photovoltaic panels, a PID-Fuzzy based controller in order to Maximize Power Point (MPP) of the inverters connected to the power network for the three-phase approach is designed. Solar arrays are connected to a three-phase network by a full -wave SCR thyristor inverter. Here, the gain of the PID controller is determined by the fuzzy controller performance and the thyristor’s fire angles are adjusted in a way that the three-phase solar network can operate at maximum power under any conditions. In this design, the solar arrays and the three-phase network by the MATLAB/Simulink have been simulated and the results are reported.
