As the development of large-scale renewable energy improves by leaps and bounds, the pressure of power system to consume renewable energy is increasing gradually. Hydrogen is extensively implemented in industry on account of its non-pollution. A hybrid system consisting of storage batteries and alkaline electrolyzers can be used to consume renewable energy. While numerous studies have focused on the proportional division of the capacity of the energy storage elements such as supercapacitors and storage batteries, without the temperature characteristics of the alkaline electrolyzer. In this paper, a control strategy based on the thermal characteristics of the alkaline electrolyzer is proposed, which can help to improve the capacity of renewable energy consumption.
