Abstract: In order to help achieve the goal of "carbon peak and carbon neutrality", this paper designs a green hydrogen system equipped with compressed air energy storage. The green hydrogen system operates off-grid, with wind and photovoltaic power providing electricity and compressed air energy storage as energy storage equipment to ensure that the electrolyzer can produce hydrogen stably for a long time. With the goal of maximizing the benefits of the system, a mathematical model of green hydrogen was established to determine the optimal capacity allocation and operation scheduling scheme, and the effectiveness and feasibility of the proposed capacity allocation and operation scheduling optimization strategy were verified through simulation analysis, and the economic analysis of the hydrogen produced was carried out. The results show that the green hydrogen system with compressed air energy storage has only 2% of the curtailment after design optimization, which can realize the efficient operation of the system and improve the economy. This study provides scientific decision support for the capacity allocation and operation scheduling of the green hydrogen system, and can provide guidance for relevant projects.
