Optimisation de la puissance d‟un GPV à l‟aide de la logique floue

Abstract

The output power of the photovoltaic generator (GPV) depends on several climatic factors, such as sunlight and temperature. However, real-time tracking of the maximum power point (MPP) is necessary to optimize the system's efficiency. The objective of this work is to study and simulate, using the MATLAB-SIMULINK environment, a fuzzy logic-based control for tracking the maximum power point of a photovoltaic system under fixed irradiance and temperature conditions. The simulation results are then presented for the Boost converter and PV-Boost converter with a fixed duty cycle. Finally, the results are presented for the fuzzy logic-based MPPT control with configurations of four, five, and seven membership functions.
