To address the issue of extreme operating conditions such as deep charging and discharging that energy storage batteries are prone to encounter when rapidly responding to grid or load disturbances, a photovoltaic-hydrogen storage DC microgrid system with maximum output power was designed. This system comprises photovoltaic cells, proton exchange membrane fuel cells, an electrolyzer, energy storage batteries, and a hydrogen storage tank. A bidirectional adaptive weighting factor power allocation strategy was proposed, which integrates the state of charge (SOC) of the energy storage batteries and the SOC of the hydrogen storage tank. High and low thresholds for the SOC of the energy storage units were set, and the power allocation weighting factor was calculated based on their SOC values ​​to dynamically allocate the power load between the energy storage batteries and the electrolyzer. During operation, considering both SOC and SOC, the 750V rated bus voltage fluctuation was less than 1.6%, and the SOC of the energy storage batteries remained within a reasonable operating range of 30% to 70%, without exhibiting extreme operating conditions under rapid grid and load disturbances. This achieved adaptive power allocation for the photovoltaic-hydrogen storage DC microgrid system, improving operational reliability.
