摘　　要：作为现代综合公共交通运输体系的重要部分,城市轨道交通系统呈现高增速、大规模发展趋势,但面临能耗高、效益低和灵活性不足等多方面挑战,其用能模式低碳高效转型需求迫切。针对计及可再生能源接入的城市轨道交通供电系统提出一种储能容量配置优化方法。首先,分析了城市轨道交通系统各组分运行模式与负荷特性,建立系统能量交互机制。其次,建立规划-运行两阶段优化模型,旨在实现峰谷分时电价机制下系统经济、碳排综合成本最小化。然后,采用列与约束生成算法迭代求解储能容量配置策略。最后,结合算例分析验证了所提方法的可行性和有效性。As an important part of the modern compre hensive public transportation system,the urban rail transit system is undergoing large-scale development.The challenges,such as high energy consumption,low efficiency,and insufficient flexibility,prompt a low-carbon and efficient transformation.A two-stage robust optimization method for energy storage capacity configuration of urban rail transit power supply systems is proposed to integrate renewable energy.Firstly,the urban rail transit system's operating modes and load characteristics are analyzed,and the system energy interaction mechanism is established.Secondly,a two-stage robust optimization model of capacity planning and dispatch of energy storage is proposed to reduce the comprehensive cost under the peak valley time of use electricity price mechanism.Then,the column and constraint generation algorithm are applied to solve this problem iteratively.Finally,the feasibility and effectiveness of the proposed method is verified through case analysis.
