Energy storage system is an important part of high-speed railway power system. Energy shift can be realized by energy storage system. Energy storage system can capture the residual energy from the regenerative braking by charging. The demand for power purchase of the system can be reduced by discharging when the traction load is high.
High-speed railway power system consists of traction power system and station power system. High-speed railway locomotives generate electrical energy that is fed back to the grid during regenerative braking, and the grid company adopts the policy of ignoring the reverse transmission, which wastes energy on the railway system.
Currently, as the key technology of smart grids and distributed generation, energy storage systems (ESSs) have attracted worldwide attention [24, 25]. The ESS can play a vital role in power demand-side management and load shifting. Moreover, the potential of an ESS in electrified railways has been widely discussed.
HIGH speed railway has developed rapidly in recent years. Traction power supply system, which is the main source of current train power, is related to the safe operation of railway transportation and power grid. Electrified railway is considered to be one of the highest energy consumption users in the public power grid .
In a word, the principles for selecting energy storage media suitable for electrified railway power supply system are as follows: (1) high energy density and high-power density; (2) High number of cycles and long service life; (3) High safety; (4) Fast response and no memory effect; (5) Light weight and small size.
Table V. Ground energy storage access scheme of electrified railway. Its voltage level is high, which can reduce the loss caused by energy transmission in the line to a certain extent, and the capacity of ESS is large. It has a low voltage level and is only suitable for short-distance transmission to supply power to station loads.
The European energy storage market is booming with Germany leading residential adoption (+58% YoY) thanks to €500/kWh subsidies. Italy's new tax credits drive 5.2GWh commercial deployments, while UK grid-scale projects exceed 8GWh with 2-hour duration systems. Key selection criteria: German-certified safety (VDE-AR-E 2510), 10+ year warranties, and VPP readiness. Top-performing products include Sonnen's hybrid inverters (98% efficiency) and BYD's Blade Battery (12,000 cycles @80% DoD). For snowy regions like Scandinavia, consider Huawei's -30°C compatible systems. France mandates carbon footprint declarations - Sungrow's ISO-14067 certified solutions gain preference.
For European homeowners, 5-10kWh systems with 3-phase compatibility are ideal. Top picks: 1) Tesla Powerwall 3 (13.5kWh, 97% round-trip efficiency) for smart home integration; 2) LG Chem RESU Prime for compact urban installations; 3) SMA Sunny Boy Storage for retrofit projects. Critical features: EU-made battery cells (exempt from CBAM tariffs), dynamic tariff optimization (like Octopus Energy integration), and fire-safe LiFePO4 chemistry. Southern Europe demands 85%+ depth of discharge capability, while Nordic markets require -25°C operation. Always verify CEI 0-21 compliance for Italian grid connection and EnWG certification for German feed-in.
