针对电气化铁路沿线新能源资源调节困难、负荷分布不均以及班列到站后装卸作业存在势能浪费的问题，提出一种跨区货运铁路储能牵引系统设计优化策略。分析移动式储能充放电的时空特性，构建了分时分区电价模型和储能牵引系统容量优化配置模型，引导负荷时移以实现在不同时域、地域跨度上的削峰填谷，提出以日运行效益最大为目标的能量管理策略。算例验证所设计的储能牵引系统及其运行策略，能有效提高班列运行周期内的经济效益、促进沿线能源消纳，对电气化铁路低碳运行具有重要参考价值。

In view of the difficulties in adjusting new energy resources along electrified railways, uneven load distribution, and waste of potential energy in loading and unloading operations after trains arrive at stations, a design optimization strategy for the energy storage traction system of cross-regional freight railways is proposed. Analyzing the spatiotemporal characteristics of mobile energy storage charging and discharging, a time-sharing zoning electricity price model and an energy storage traction system capacity optimization allocation model were constructed to guide load time shifting to achieve peak shaving and valley filling in different time domains and geographical spans. It was proposed that an energy management strategy aiming at maximizing daily operating efficiency. The calculation example verifies that the designed energy storage traction system and its operation strategy can effectively improve the economic benefits during the operation cycle of the train, promote energy consumption along the line, and have important reference value for the low-carbon operation of electrified railways.
