Performance Analysis and Comparison Between Fuzzy Logic Algorithm and PI-Controller in Photovoltaic System

Technologies based on renewable energy are maturing into viable choices for providing quick, dependable power to every home in the world. Since solar radiation, cell temperatures, and environmental conditions all fluctuate, the output power from solar photovoltaic modules is unpredictable. Therefore, maximum power point trackers are required to maximize solar energy collection and enhance photovoltaic system performance. In this article, we'll deal with two MPPT controllers that are different from each other in approach, Performance in tracking toward fast irradiance and temperature change is examined between a proportional-integral (PI) controller and a fuzzy logic controller by MATLAB/Simulink. Based on the simulation results, it was clear that the fuzzy logic controller outperformed the PI controller. The fuzzy logic controller can dampen oscillation while also providing a fast reaction to fluctuations in solar radiation, and unlike the conventional PI controller, it doesn't even need the settings adjusted.
