Abstract

This paper proposes an integrated energy management strategy of green electric-green hydrogen to achieve coordinated and stable operation of the system under multiple time scales. Based on analytic hierarchy process（AHP） and entropy weight method, the optimal capacity ratio scheme of alkaline electrolzser（AEL） and proton exchange membrane electrolyzer（PEMEL） was calculated to improve the carrying capacity of green hydrogen system. Considering the working characteristics of AEL and PEMEL, a refined simulation model is established that includes wind power hydrogen production hydrogen storage units. A hierarchical control method is adopted to improve the coordinated operation ability of the system. At the same time, nine complex energy management strategies are proposed, including residual electricity hydrogen production, load power compensation, and source load coordinated operation, to promote the efficient utilization of wind power resources and effectively improve the power balance relationship of the green power green hydrogen integrated system.
