Modelling and Control of a Grid-Connected RES-Hydrogen Hybrid Microgrid

This paper proposes a Hybrid Microgrid (HμG) model including distributed generation (DG) and hydrogen-based storage system, controlled through tailored control strategy. The HμG is composed of three DG units, two them supplied by solar wind sources, the latter one based on exploitation theProton Exchange Membrane (PEM) technology. Furthermore, system includes an alkaline electrolyser, which used as responsive load to balance excess Variable Renewable Energy Sources (VRES) production, produce hydrogen that will be stored into tank supply fuel cell in case lack generation. main objectives this work are present validated dynamic for every component provide strategy reduce much possible power absorption from grid exploiting VRES production. electrolyser PEM models real measurements. State Charge (SoC) adjusted adaptive scheme. designed supervisor allows reducing exchange improving stability. Finally, case, considering summer profile measured electrical substation Politecnico di Torino, presented. results demonstrates advantages micro-grid, where medium store energy produced photovoltaic systems, with aim improve self-sufficiency system.
