Abstract:

This paper proposes an advanced energy management system (EMS) for a stand-alone hybrid energy system. The considered hybrid system includes a photovoltaic panel, a fuel cell, an electrolyzer and a battery bank. The EMS aims to optimize the utilization cost of the hybrid power system and to improve its energy balance with the elimination of any energy deficit.The hybrid power system has been tested by simulation using models implemented in Matlab/Simulink software. The simulation is performed over a long period of time in order to evaluate the effectiveness of the management strategy. The simulation results confirm the efficiency of the proposed control strategy, as it increases the reliability of the system and improves its energy balance.
