Analysis of MPPT Methods: P & O, INC and Fuzzy Logic (CLF) for a PV System

The MPPT (Maximum Power Point Tracking) control unit is an essential part for the photovoltaic system optimal operation. In addition to the protection function, this command ensures the continuation of the maximum power point (MPPT) and allows the PV generator to deliver its maximum power regardless of the variation in climatic conditions (sunshine and) temperature). This work intends to provide a comparative study of different techniques to track the maximum power point (MPP) from the photovoltaic array. Disturbs and observes P&O, incremental conductance INC and fuzzy logic based FLC strategies are analyzed and their simulation under unsteady state conditions has been performed using MATLAB SIMULINK for the purpose of showing the advantages of each of them
