Contribution à l’étude d’un système de pompage photovoltaïque

Abstract

This work concerns the contribution to the study of a photovoltaic pumping system. The main objective of this thesis is to improve the performance and the efficiency of a photovoltaic system through the use of an efficient and optimal algorithm to extract the maximum power available from the PV array. We propose in this work, a new method based on the current perturbation algorithm (CPA) and the constant short-circuit current algorithm (FSCC). The method based on artificial intelligence such as fuzzy logic has shown great efficiency. The realization of a boost chopper and implementation of MPPT algorithms based on a dSPACE card and performing a pumping system has completed that work
