Hybrid renewable energy systems (HRES) are attractive configurations used for different applications and especially in standalone power generation systems as electrification, water pumping, and telecommunications. Considering the multitude of sources, energy management control (EMC) will be necessary. In this paper, supervision of hybrid Wind/ Photovoltaic/Diesel system with battery storage is presented. The power balance of the suggested system is made on an intelligent supervisor based on fuzzy logic control (FLC). It is simple, easy and makes it possible to determine the various operating processes of the hybrid system according to the weather conditions. The decisions of criterion required by this method are presented. The study was implemented under Matlab/Simulink and an application is made for Bejaia a site in the coastal region of Algeria. The obtained results are presented and show the feasibility of the proposed control system. (C) 2017 Hydrogen Energy Publications LLC. Published by Elsevier Ltd. All rights reserved.
