Control strategy and simulation analysis of wind-solar-storage integrated coupling hydrogen production system

To realize the national energy strategy goal of carbon neutrality and carbon peaking, hydrogen production from wind power and photovoltaic green energy is an important technical way to achieve the dual-carbon goal. Given the random and strong fluctuation of wind power and photovoltaic power, the hydrogen production system of electrolytic water is unstable and the effect of hydrogen production is unsatisfactory. Based on the establishment of a wind power, photovoltaic, and energy storage coupled hydrogen production system, a control strategy based on DC bus voltage stabilization is adopted for the purpose of improving the quality of power generation, smoothing hydrogen production, and enhancing the stability of the system, which can ensure the stability of the bus voltage and the smoothness of the hydrogen production in spite of the perturbation conditions; By using MATLAB/SIMULINK simulation platform to build a wind-solar-storage integrated coupling hydrogen production system, the simulation results verify the effectiveness of the proposed control strategy and improve the stability of the system.
