“…The scale and characteristics of power loads in railways vary with speed, number of cars, and density of trains [6,7]. Studies have been conducted on the operation of ESSs for trams [8,9], urban lines [10][11][12], and high-speed railways [13][14][15][16], depending on the situation. In one study [8], an energy management control method for a light rail vehicle (LRV) transportation system using lithium-ion capacitors was proposed, and experiments using a reduced-scale model of the real system demonstrated that the method reduces peak current and energy consumption.…”

“…However, for regenerative power utilization, as discussed earlier, the locations where the introduction of ESSs is expected to be effective are limited. Moreover, the locations in previous studies [8][9][10][11][12][13][14][15][16] were considered based on the assumption that the ESS would be introduced at locations with high effectiveness. In fact, the ESSs that were introduced on Japanese railroads were limited to a few metropolitan areas [6].…”

The peak demand for railway power occurs when trains operate at full capacity, which calls for the need of facilities that can handle such peaks. These expansive railway power facilities, which cover vast areas, result in increased maintenance and management costs while affecting the power supply to traction substations (TSs). Herein, we investigated the load leveling of TSs using energy storage systems (ESSs). Most of the studies that have been conducted on the use of ESSs in electric railways have focused on high‐speed railways and urban lines. The application of ESSs to local lines is expected to be highly effective in reducing the capacity of power facilities using the load leveling of TSs. However, the introduction of ESSs to such local lines has not yet been discussed in detail. Hence, we focused on the relationship between ESS specifications (battery capacity, kWh) and load peak reduction (kW) and proposed a method to determine the ESS specifications by simultaneous optimization using linear programming. Numerical calculations were performed based on measured data from a real line, and the proposed method was verified in terms of battery capacity, load peak reduction, and ESS operation ratio. The numerical results indicate that the maximum load of the TS can be reduced by 98.7% and 91.1% using 380 kWh and 65.42 kWh ESS, respectively, considering its cooling time. This highlights the potential of Energy Storage Systems (ESSs) to balance TS (Time‐of‐Use) loads and consequently reduce power facility requirements. © 2024 The Authors.

“…To supply the active power, energy storage systems have been proposed to install on board [8] or at the substation and section-post [9][10][11][12]. Although the on-board system has the advantage of optimally utilizing the regenerative energy by mounting an energy storage device on the vehicle, it has disadvantages of increasing the weight of the vehicle and constraining the installation space [13,14]. For this reason, installing energy storage systems at the station using high-power and large capacity energy storage systems (ESSs), such as a flywheel [10], electric double layer capacitors (EDLCs) [11], or Li-ion batteries [12], has been considered.…”

: The control and operation of a single-phase 13-level power conditioning system (PCS) for peak power reduction of a high-speed railway substation (HSRS) are proposed. This PCS is a single-phase 3100 V, 2 MVA 13-level H-bridge multi-level inverter structure. It has excellent power quality. It is easy to serialize by voltage. In addition, the DC bus power of each cell inverter is supplied by lithium-ion batteries. The generalized reduction gradient optimization algorithm based on past load pattern is applied to the power management system for peak power reduction of HSRS. The phase detector and power controller for the control of a single-phase PCS based on virtually coordinated axes using an all-pass filter are expected to be robust to external disturbances with fast response characteristics. This study also proposes an adapted select switch (ASS) method that can change the switching depending on the operation state of PCS and the state of charge (SOC) of the battery to minimize battery imbalance by controlling each cell inverter of the H-bridge. The validity of the proposed system was confirmed by PSiM simulation and experiments using a demonstration system of 6 MW PCS and 2.68 MWh batteries at one of Gyeongbu high-speed line substations in Korea.
