Modeling and Control of a Photovoltaic-hydrogenbattery microgrid by Energetic Macroscopic Representation

This paper proposed a macroscopic Energetic Macroscopic Representation (EMR) model for integrated photovoltaic-hydrogen-battery systems to address the challenges of intermittency and grid instability in renewable energy utilization. By establishing a multi-energy coupling model, the study explores the dynamic interactions between the subsystems. In addition, considering the operation states of electrolyzer and battery, a control strategy is suggested to achieve effective energy management for the hybrid system and simulation results demonstrate that the proposed system can efficiently utilize PV generation while enhancing the operational efficiency of the electrolyzer.
