To solve the difficulties and high cost of constructing electrified railway traction power supply systems while using traditional 110 kV/220 kV strong grid solutions in non-electric railway,a novel traction power supply system based on energy storage(ES)with new energy such as wind and light as the main body is proposed.This paper systematically summarizes the ES technology categories,working principles,mathematical models,and typical applications of the novel traction power supply system and elaborates on the ES technology attributes suitable for the novel traction power supply systems.Meanwhile,it characterizes the connotation,features,and form of the novel traction power supply system and presents the electrical topology,measurement and control platform,monitoring network,and control logic architecture of the system.In response to the strong random fluctuation characteristics of the source and load sections in the novel traction power supply system,this paper discusses two major supporting theories from an entirety perspective:the interaction mechanism of components and the stable operation mechanism of the system;the energy flow balance mechanism and the system efficiency emergence mechanism,as well as other key technologies:the planning and optimization configuration,the efficient transformation of electricity,the self-contain scheduling for energy,and the efficiency evaluation and performance maintenance.It can be seen that the novel traction power supply system based on energy storage can achieve the electrification upgrades featuring green,low-carbon,resilience,self-contain and cost-effective for the non-electrified railways and further provide references for the subsequent closed-loop research on the“theoretical research-simulation verification-experimental verification-evaluation optimization”.
