With the rapid development of high-speed and heavy-load electrified railway, the peak impact and the regenerative braking energy content of traction load become increasingly significant, which has become an important problem affecting the construction and operation benefits of electrified railway. On the basis of comprehensively solving the power quality problems of electrified railway, a multi-application strategy based on the railway static power conditioner (RPC) with the energy storage system (ESS) is proposed in this paper to improve the economic benefits of the traction system. Through the implementation of the peak clipping and the recuperation and utilization of regenerative braking energy of traction load with the guidance of such strategy, the comprehensive economic benefits of the traction system can be improved. By analyzing the mathematical relationship between the comprehensive economic benefits and the parameters such as peak clipping rate and regenerative braking energy utilization rate of the system, an optimization model with the goal of maximizing the comprehensive economic benefits is established. Therefore, the optimal configuration capacity of the ESS is obtained. Finally, the experiments are carried out in MATLAB. The results show that, with the multi-application strategy, the peak load clipping and the recuperation and utilization of regenerative braking energy can be simultaneously realized. It is also demonstrated that the comprehensive economic benefits and environmental benefits can be improved while improving energy efficiency.

基于储能系统的铁路静态功率调节器多应用策略

随着高速重载电气化铁路的飞速发展，牵引载荷的峰值冲击和再生制动能含量变得越来越重要，这已成为影响电气化铁路建设和运营效益的重要问题。在全面解决电气化铁路电能质量问题的基础上，提出了一种基于铁路静态功率调节器（RPC）和储能系统（ESS）的多应用策略，以提高牵引的经济效益。系统。通过在这种策略的指导下实施削峰和牵引负荷的再生制动能量的回收利用，可以提高牵引系统的综合经济效益。通过分析综合经济效益与系统的削峰率，再生制动能量利用率等参数之间的数学关系，建立了以综合经济效益最大化为目标的优化模型。因此，获得了ESS的最佳配置能力。最后，在MATLAB中进行了实验。结果表明，通过多应用策略，可以同时实现峰值负载削峰和再生制动能量的回收利用。还表明，在提高能源效率的同时，可以改善综合经济效益和环境效益。
