Abstract
In this paper, a design of a Hybrid autonomous Power System is proposed and detailed. The studied system integrates several components as solar energy source, Energy Recovery system based on a proton membrane exchange fuel cell system and two energy storage components, namely, (1) Energy Storage based on H2 gas production, and (2) an Ultra-capacitor storage device. The system is controlled through an energy management Unit which aims to ensure the smooth operation system to be against any unexpected fluctuation. The modelling of the system relies on the application of a multi-agent strategy whose good effects on the performance of the system is evaluated and demonstrated by the obtained simulation results. The improvement of the system performance is proved through a comparison with the conventional strategies. The system that relies on multi-agents control approach seems to be more reliable and promising in term of effectiveness and fast response.
Highlights
Recourse to the use of renewable energies becomes a necessity in view of the extravagant consumption of fossil energy which presents harmful effects on the environment such as the release of carbon dioxide (CO2) and the emission of greenhouse gases that affect the global climate balance.The renewable energy resources appear to be a promising replacement to the exhaustible natural resources
The Ultra-capacitor Storage Component (USC) is used as energy storage when the Solar Energy Component (SEC) generates an exceeded power when there is an interruption of the hydrogen production process: charge mode

Summary
Recourse to the use of renewable energies becomes a necessity in view of the extravagant consumption of fossil energy (coal, oil, natural gas, uranium, etc.) which presents harmful effects on the environment such as the release of carbon dioxide (CO2) and the emission of greenhouse gases that affect the global climate balance. In [5], the authors proposed an accurate hybrid feeding system They used an energy management unit to control the load demand and the energy source, such as the solar photovoltaic (PV) network, the fuel cell and the battery. They integrate long-term energy storage (hydrogen (H2)) in the proposed system to manage the output power fluctuations. This work presents a comparative study between different management strategies but it focuses at the level of results on the presentation of the battery state of charge (SOC) and the hydrogen tank pressure without mentioning the parameters already described by the management algorithm.
