Abstract: In the planning and construction of renewable energy-driven hydrogen production projects, there exists a closely interdependent coupling relationship among the installed capacities and configurations of renewable power generation systems, energy storage systems, hydrogen electrolyzers, and downstream hydrogen demands. This interrelationship is critical for the overall optimization of the system. Particularly, as energy storage devices encompass electrochemical storage and hydrogen storage facilities, which serve similar functions, the rational optimization of their capacity allocation presents a significant challenge. To enhance the overall utilization efficiency of renewable energy and reduce the peak regulation load on the main grid, further optimization of the proportions of renewable energy scale, load, and storage capacity in green hydrogen production projects is essential. This study establishes a wind-solar-storage-hydrogen system model, defines the system constraints, control objectives, and control algorithms, and constructs a simulation framework to optimize the configuration of wind, solar, storage, and hydrogen components. Through simulation analysis, the optimal configuration is identified.
