Contribution à l’optimisation du transfert d’énergie d’un système photovoltaïque par les techniques intelligentes

Abstract

This work aims to develop two new algorithms based on the synergetic adaptive approach to achieve maximum power in a stand-alone photovoltaic system. This system is composed of a photovoltaic generator, a DC-DC boost converter, a resistive load and an MPPT controller. Each algorithm is used to control the boost converter using a duty cycle signal to fully exploit the output power of the photovoltaic (PV) generator which depends on irradiance and temperature. The energy transfer for both algorithms was optimized using the PSO algorithm to improve performance and reduce losses. The efficiency and robustness of both algorithms were evaluated using the MATLAB/Simulink environment under various climatic conditions. A comparative study was also conducted with a modern technique to demonstrate the effectiveness of both proposed approaches.
