【摘要】 可再生能源电解水制氢技术中电解槽是制氢的关键设备，其性能直接影响着制氢的效率、稳定性和成本。本文针对风光储氢系统中混合电解槽的容量配置问题，提出了基于灵活性指标的混合电解槽容量配置优化方法,首先，基于波动适应性、制氢能效、运行条件以及经济性4个角度构建灵活性评价指标体系，全面评估电解槽在多种工况下的综合性能。其次，结合AHPDEMATEL方法，确定权重分配。最后，将灵活性指标嵌入优化框架中，开展对混合制氢系统的配置策略研究。算例结果表明，所提出的混合电解槽容量优化配置方案与单一电解槽配置方案相比，制氢成本相比单一质子交换膜电解槽配置方案显著降低，制氢量相比单一碱性电解槽方案相应提高，为混合电解槽的选型与评价提供新方法。更多还原

【Abstract】 The electrolyzer is a key equipment in renewable energy electrolysis hydrogen technology, and its performance directly affects the efficiency, stability, and cost of hydrogen production. An optimization method for the capacity configuration of mixed electrolysis cells in wind solar hydrogen storage systems based on flexibility indicators is proposed. Firstly, a flexibility evaluation index system is constructed from four perspectives:fluctuation adaptability, hydrogen production efficiency, operating conditions, and economy, to comprehensively evaluate the comprehensive performance of electrolysis cells under various operating conditions. Secondly, combining the AHP-DEMATEL method to determine the weight allocation. Finally, the flexibility index is embedded into the optimization framework to conduct research on the configuration strategy of the hybrid hydrogen production system. The simulation results show that the hybrid electrolyzer capacity optimization configuration scheme proposed in this paper is significantly lower in hydrogen production cost than the single electrolyzer configuration scheme, correspondingly higher in hydrogen production volume than the single alkaline electrolyzer scheme, and provides a new method for the selection and evaluation of hybrid electrolyzers.更多还原
