Abstract：Hydrogen production from renewable energy is of great value to stabilize the volatility of renewable energy and realize the green acquisition of hydrogen energy. In this paper, the electrothermal characteristics of alkaline electrolyzers are summarized, and the constraints such as power regulation characteristics, start-up and shutdown characteristics are summarized, and a coordinated control strategy of alkaline electrolyzer array with rotation mode is proposed. The simulation results show that the optimal control strategy of the array rotation is effective, which can effectively improve the service life and operation safety of the electrolytic cell array and reduce the investment while ensuring the absorption effect. The research results can provide reference for the engineering application of fluctuating power consumption based on alkaline electrolyzer.

Key words： Wind power generation alkaline electrolysis cell working characteristics capacity allocation optimal control strategy
