摘　　要：未来绿氢的规模化发展需要走工艺离网型的技术路线。为此,结合风力/光伏发电、碱性-质子交换膜(ALK-PEM)电解槽和储能设备,构建风光耦合制氢系统,对其多目标优化配置进行研究。采用密度峰值优化的近邻传播快速聚类算法得到风光联合出力典型场景;考虑ALK-PEM电解槽的特点,提出电解制氢单元的功率分配策略,结合风光耦合制氢系统的能量流动模式,以减小系统成本、提高系统能量效率和可再生能源利用率为目标,构建系统容量配置优化模型,并采用多机制第三代非支配排序遗传算法进行求解;对混合电解槽制氢系统与混合电解槽-储能协同制氢系统的多项指标进行对比分析。仿真结果表明:相比于混合电解槽制氢系统,协同制氢系统中的储能设备能够实现对电解槽功率的补偿,使得ALK电解槽所占比重有所提升,显著降低电解槽的启停次数,单位制氢成本和弃风弃光率分别降低了8.76%、54.01%,系统能量效率和内部收益率分别提高了34.85%、13.58%,验证了所提模型的有效性与灵活性。The large-scale development of green hydrogen in the future needs to take the technical route of off-grid system.Therefore,a wind-solar coupling hydrogen production system is constructed by combining the wind/photovoltaic power generation,alkaline(ALK)-proton exchange membrane(PEM)electrolyzers and energy storage equipment,and its multi-objective optimal configuration is studied.The typical scenarios of wind-solar joint output are obtained by using the affinity propagation fast clustering algorithm with density peaks optimizing.Considering the characteristics of ALK-PEM electrolyzers,the power distribution strategy of electrolysis hydrogen production unit is proposed.Combined with the energy flow mode of wind-solar coupling hydrogen production system,the capacity configuration optimization model of the system is constructed with the goal of reducing system cost and improving system energy efficiency and renewable energy utilization rate,which is solved by the non-dominated sorting genetic algorithm-Ⅲ.Several indexes of the hydrogen production system based on hybrid electrolyzers and the collaborative hydrogen production system based on hybrid electrolyzers and energy storage are compared and analyzed.The simulative results show that,compared with the hydrogen production system based on hybrid electrolyzers,the energy storage equipment in the collaborative hydrogen production system can realize the power compensation of electrolyzers,so that the proportion of ALK electrolyzer is increased and the start-stop times of electrolyzers are significantly reduced.The unit hydrogen production cost and the wind-solar abandonment rate are reduced by 8.76%and 54.01%respectively,and the system energy efficiency and the internal rate of return are increased by 34.85%and 13.58%respectively,which verifies the effectiveness and flexibility of the proposed model.
