摘　　要： 针对城市电网负荷峰谷差大导致电力资源大量浪费的现状,提出城市电网耦合氢储能系统方案用于消纳电网负荷低谷时段富余电能。通过对氢储能系统运行周期内的投资成本和经济收益进行分析,构造投资决策评价模型,并根据投资者不同的投资需求建立三种优化模型:氢气最低销售价格模型、氢储能系统最优装机容量模型和特定投资回收期下氢气最低销售价格模型。以某城市电网用电负荷数据为基础,利用上述模型对在该城市实施城市电网耦合氢储能系统方案时不同投资需求下的最优方案进行了分析。 The peak-valley load difference of urban power grid leads to a large waste of power resources. Urban power network couped to hydrogen energy storage system is proposed here to dissipate surplus power during low load period. Based on the analysis of investment cost and economic benefit in the life cycle of hydrogen storage system, an evaluation model for investment decision making is built which involves three optimization models according to the different investment demands： the minimum hydrogen selling price model, the optimal installed capacity model and minimum selling price model under given payback period. Finally, based on the real data of a certain city grid load, the optimal scheme is analyzed under the different investment demand when the urban power grid coupled to hydrogen energy storage system is implemented in the city.
