To realize the“carbon peaking and carbon neutrality”target and the rapid growth of Chinese railway mileage,energy saving and efficiency increasing have become the future development trend of the railway.As a key means to improve resilience and reduce system energy consumption,large-scale access of energy storage to electrified railways is imperative.Therefore,systematic research on the energy storage system of electrified railway is carried out to provide a reference for large-scale application of the system.Firstly,the selection principle of energy storage system for electrified railway is analyzed.In practical application,the selection should be combined with traction load power characteristics,installation location,and other factors.Secondly,the access schemes of electrified railway energy storage system under different power supply modes are compared and analyzed.In order to meet the power demands of railway system,the access scheme design of energy storage system should meet the characteristic requirements of being more efficient,reliable,modular and intelligent.Thirdly,the power quality control scheme and control strategy of electrified railway power supply system based on energy storage are analyzed.The energy storage system can effectively improve the power quality of electrified railway power supply system.Finally,the construction achievements of rail transit energy storage technology demonstration project are summarized,and the prospects in key problems of future research on energy storage system of electrified railway are put forward.
