To read more deal with energy transition due to climate change and a rise in average global temperature, photovoltaic (PV) conversion appears to be a promising technology in sunny regions.However, PV production is directly linked with weather conditions and the day/night cycle, which makes it intermittent and random.Therefore, it makes sense to combine it with Energy Storage Systems (ESS) to ensure long-term energy availability for non-interconnected micro-grids.Among all technological solutions, electrolytic hydrogen produced by renewable energies seems an interesting candidate.

In this context, this paper proposes a control strategy dedicated to hydrogen storage integration in micro-grids for a better use of PV production.The objective is to optimize the management of the here micro-grid with proton exchange membrane Fuel Cell (FC), alkaline Electrolyzer (El), lithium-ion Batteries Energy Storage System (BESS) and PV, according to the system state and PV production intermittency.First, a control strategy based on a Distributed explicit Model Predictive Control (DeMPC) is developed to define current references for FCs, Els and batteries.Secondly, the performance of the control strategy is validated in simulation and confirmed on a Power-Hardware-in-the-Loop test bench.
