Summary and Outlook of Capacity Configuration and Energy Management Technology of High-speed Railway Energy Storage System|高速铁路储能系统容量配置与能量管理技术综述与展望

High-speed railway traction energy consumption increases with the continuous expansion of high-speed railway network in China, and problems such as low utilization rate of locomotive regenerative braking energy are becoming increasingly prominent. To reduce traction energy consumption in the context of carbon neutrality, this paper compared and analyzed the current common energy storage media, and proposed three types of energy storage scheme topologies: fixed ground, mobile on-board, and hybrid ground-vehicle, based on the characteristics of different energy storage media. On this basis, this paper reviewed energy management schemes based on thresholds and distribution ratios, and briefly described the "source-network-storage-locomotive" cloud-sensing energy management system based on the railway energy storage system, emphasizing the coordination of source, grid, storage, and locomotive. This paper systematically discussed the current research status of high-speed railway energy storage system capacity configuration and energy management, summarized the key technical issues of high-speed railway energy storage system, and provided corresponding reference for high-speed railway energy storage system engineering.
