For the voltage control problem of the distributed direct current hydrogen production system, this paper proposes a dual-layer coordinated voltage regulation strategy based on the synergy of electrolyzers and energy storage, which consists of a fast response layer and an economic dispatch layer. The fast response layer achieves rapid voltage regulation through the active- voltage droop control of energy storage and electrolyzers. The economic dispatch layer comprehensively considers multiple economic factors such as hydrogen production benefits, energy consumption costs, energy storage losses, and depreciation of cycle life, and constructs an electrolyzer-energy storage coordinated control optimization model with the goal of minimizing the overall system operation cost. The Gurobi solver is used to complete the economic power allocation between the energy storage and hydrogen production modules. Simulation results show that the proposed strategy can effectively reduce the amplitude of voltage fluctuations and achieve a balance between voltage regulation performance and economic operation indicators, providing a solution that combines technical feasibility and economic rationality for the voltage control of the distributed direct current hydrogen production system.
