Coordinated Control Strategy for Hydrogen-Containing Hybrid Energy Storage Microgrid

The study introduces the Dynamic Response Regulation System, which considers the multi-state of hydrogen energy. This novel approach addresses the power discrepancy resulting from response delays in electrolyzers and fuel cells. The system integrates batteries and supercapacitors to form a response compensation mechanism, which proposes a power distribution strategy that considers the supercapacitor's state of charge (SOC). The system demonstrates proficiency in the management of power fluctuations across a range of frequencies, thereby ensuring the stability of the microgrid's operation. A hydrogen storage energy management strategy has been formulated based on the actual response of the battery and the state of charge (SOC), with the objective of further enhancing the system's efficiency in maintaining power balance and the stability of the direct current bus voltage. The case analysis and simulation results substantiate the efficacy of this innovative system in attaining the aforementioned objectives.
