Asymmetrical Fuzzy Logic-Based Controller for MPPT in Photovoltaic Application

摘要

The proposed work studies the simulation of a standalone Photovoltaic (PV) system. Maximum Power Point Tracking (MPPT) plays an essential role in maximizing the output power from photovoltaic array under varying conditions of irradiation and surface temperatures. This in turn yields maximum efficiency and reduces the overall system cost. For the purpose of tracking maximum power, an intelligent asymmetrical fuzzy logic control MPPT algorithm has been developed for the PV system. The developed algorithm has been simulated using MATLAB Simulink toolbox. In order to show the superiority of the developed algorithm, the results of this technique have been compared with conventional P and O algorithm.
