摘　　要：利用可再生能源电解水制氢是实现能源转型和电力脱碳的关键技术。然而,功率波动和频繁启停是造成碱性电解槽运行寿命衰减的重大因素。为此,在分析电解槽单体运行特性的基础上,提出了考虑多电解槽多工况组合运行的电-氢-热综合能源系统优化调度模型。针对风电出力不确定性引起的实时调度阶段电解槽工况切换以及储能工作模式切换,建立了两阶段鲁棒调度模型,并采用嵌套列和约束生成算法对其进行求解。以4个不同场景算例进行仿真实验,结果表明,考虑多电解槽之间的灵活组合及其在实时调度过程中工况的快速切换可提高系统运行经济性,并可有效缓解电解槽功率波动引起的运行寿命衰减。Producing hydrogen through water electrolysis using renewable energy is a key technology to achieve energy transformation and electricity decarbonization.However,power fluctuation and frequent start-stop are major factors causing the operating life decay of alkaline electrolyzer.Therefore,based on the analysis of the operation characteristics of the electrolyzer monomer,an optimal scheduling model of the electricity-hydrogen-heat integrated energy system considering the combined operation of multi-electrolyzers under multiple operating conditions is proposed.A two-stage robust scheduling model is established to deal with the working mode switching of the electrolyzer and energy storage system during the real-time scheduling stage caused by wind power uncertainty,which is solved by the nested column and constraint generation algorithm.The simulation experiments are carried out under four different scenarios,and the results show that considering the flexible combination of multi-electrolyzers and the rapid switching of operating conditions during the real-time scheduling stage can improve the operational economy of the system and effectively alleviate the degradation of operating life caused by the power fluctuation of the electrolyzer.
