Traction substation energy storage system TPSS Traction power supply system TSS Traction substation URT Urban rail transit 1. Introduction1.1. Low-carbon target and railway energy transition in China With climate change becoming a …
[PDF] Coordinated Control Strategy of Railway Multisource Traction System With Energy Storage and Renewable Energy …
Influenced by the growing daily travel demand of citizens and extension of urban land, the construction of the urban railway transit (URT) system is gradually increasing nowadays. This situation implies more electricity consumption in URT and more challenges to URT operation stability. Therefore, based on the existing traction substation, this …
Study on Energy Storage and Cost Saving Scheme of Traction Substation
Abstract. Based on the energy-saving and economical operation requirements of high-speed railways, the traction power supply system adopts large-capacity energy storage devices. The paper takes the measured data of a traction substation as an example to compare the energy-saving effects of the two energy …

Maximizing regenerative energy utilization is an important way to reduce substation energy consumption in subway systems. Timetable optimization and energy storage systems are two main ways to improve improve regenerative energy utilization, but they were studied separately in the past. To further improve energy conservation while …
Optimized sizing and scheduling of hybrid energy storage systems for high-speed railway traction substations
However, little attention has been paid to the interaction of optimal size and daily dispatch of HESS within the entire project period. Therefore, a novel bi-level model of railway traction substation energy management (RTSEM) system is developed, which includes

Negative Sequence Current Compensation And Energy Management Optimization Of Traction Network Based On Series Energy Storage …
The load characteristics of high-speed railway systems have an adverse effect on the three-phase symmetry of the power supply system. A back-to-back converter connected in series to a supercapacitor energy storage device is used to solve the three-phase imbalance problem and the regenerative braking energy recovery problem of trains that occurs …
Optimal Sizing and Energy Management of Hybrid Energy Storage System for High-Speed Railway Traction Substation …
This paper studies a hybrid energy storage system (HESS) for traction substation (TS) which integrates super-capacitor (SC) and vanadium redox battery (VRB). According to the characteristics of the traction load under actual operating conditions, an energy management strategy with fixed-period control (FPC) is proposed, which fully …
