In this paper, we present an autonomous Hybrid Power system (HPS) whose main goal is to ensure the electricity production without interruption in any remote areas. To achieve this goal, the system is composed of two energy sources one, as a renewable energy, serves to primary load feeding while the other, based on hydrogen conversion, works as a backup system. Thus, the system includes two kinds of energy storage devices one is used to chemical form energy storage (H₂ gas) while the second, based on ultracapacitor storage, is dedicated to electricity power saving. The functioning of system depends on a smart energy management that is based on the decision making and the control of all the system components states to achieve a high efficiency and better performance. Hence, the reliability and the effectiveness of the proposed system are tested by Matlab/Simulink environment, from which, the obtained results have been presented and discussed in details.
