Power Management Control of photovoltaic/Batteries/Fuel cells System

Abstract

A study of a stand-alone photovoltaic./batteries/fuel cell power system has been presented in this paper to produce energy continuously. A management control circuit (PMC) has been designed to obtain the different control signals that allow supervising power flow of the hybrid system. The application has been made to a stand-alone system for four days at Bejaia region. Fuzzy logic Control (FLC) is used to optimize power The structures PV/Battery/Fuel cells system have been investigated. A modelisation of each component has been made. A supervisor control circuit has been designed to obtain the various control signals needed to control the overall system. A simulation study has been done in Matlab. The different results are presented to show the effectiveness of the proposed strategy
