hybrid energy storage system combining the batteries and su percapacitors is conducted [28], where the train power profiles, battery cycles and depth of discharge (DOD) are considered.
Energy storage is crucial for China''s green transition, as the country needs an advanced, efficient, and affordable energy storage system to respond to the challenge in power generation. According to Trend Force, China''s energy storage market is expected to break through 100 gigawatt hours (GWh) by 2025.
Rail transport is an important mode of long-distance transportation in China. As of 2024, the country had more than 159,000 km (98,798 mi) [6] [a] [7] of railways, the second longest network in the world. [2] [8] By the end of 2023, China had more than 45,000 kilometres (27,962 miles) of high-speed rail (HSR), the longest HSR network in the world.
