MPPT commands for a photovoltaic generator using the Incremental Conductance Method and the fuzzy logic command

Abstract

In the era of sustainable development, photovoltaic (PV) technology has shown significant potential as a renewable energy source. Photovoltaic generators (GPV) have a non-linear current-voltage characteristic, with a maximum power point (MPP) characterized by an optimal voltage, and depends on environmental factors such as temperature and irradiation. To extract each time the maximum power available at the terminals of the GPV and transfer it to the load, an adaptation stage is used, consisting of a Boost chopper controlled by a maximum power point tracking technique (MPPT) through a stage of pulse width modulation (PWM). Our choice has focused on two techniques which are: the Incremental Conductance Method (InCond) and that of control using the fuzzy logic. The implementation and simulation of the system (photovoltaic generator, chopper Boost, PWM and MPPT techniques) are then performed in the Matlab/Simulink environment.
