A Coordination Control Method of Alkaline Hydrogen Production System Driven Directly by Wind Energy

Wind power generation has been widely used in the world. However, in some remote islands or mountainous areas, connecting wind power to the grid is a challenging task. To solve this problem, hydrogen production from wind power directly by using alkaline electrolyzer is a method worth studying. In view of this situation, a coordinated wind-hydrogen control method is proposed in this paper. The adaptive power and voltage control strategy between the wind turbine and the alkaline electrolyzer is designed using the voltage level of the DC bus as the information carrier, so that the output power of the wind turbine is consistent with the power consumed by the electrolyzer. Finally, the proposed conclusions are verified by hardware experiments.
