Optimization scheduling control strategy of wind-hydrogen system considering hydrogen production efficiency

Because the efficiency of the hydrogen production is closely related to the optimal scheduling strategy and economy of the wind-hydrogen coupling system, an optimal scheduling method for the wind-hydrogen system considering the efficiency of the wind power hydrogen production is proposed in this paper. Taking hydrogen production from alkaline electrolysers as an example, a method to improve the efficiency of electrolyser arrays based on the segmented fuzzy control is proposed. An optimization scheduling model of wind-hydrogen system considering the efficiency of the wind power hydrogen production is built, and the optimal hydrogen production power is solved by the Artificial Bee Colony algorithm. The sensitivity analysis of the factors that affect the efficiency of wind-hydrogen system is carried out. The validity and correctness of the proposed method is verified by the simulation analysis of the actual operation data of the power grid. Compared with the traditional simple start-stop scheme, the control strategy proposed in this paper can produce more hydrogen of 6.18 tons and improve the hydrogen production efficiency by 4.8%, which can provide a theoretical basis for the large-scale application of hydrogen energy storage systems in the power grid.
