MAXIMUM POWER POINT TRACKER USING GENETIC FUZZY CONTROLLER FOR PHOTOVOLTAIC GRID CONNECTED ARRAY
Résumé
ABSTRACT
paper presents a fuzzy logic controller (FLC) used as a maximum power point tracker(MPPT) of a line commutated inverter in
a photovoltaic (PV) grid connected system, under variable irradiance conditions. The purpose is to find the relationship
between the maximum power point (MPP) and weather parameters and track the MPP and transferring the maximum power to
utility grid. The design of control rules were found by genetic algorithms (GAs) to modulate the firing angle of the inverter for
tracking the MPP. Simulation results prove the superior tracking efficiency of the fuzzy controller optimized under variable
parameters.
