摘　　要：高速铁路列车在以下坡方向经过长大坡道路段时会产生大量的再生制动能量,若将此能量合理回收利用将有利于低碳交通与节能减排,实现“3060”双碳目标,更有利于列车行车安全。针对地面式再生制动能量混合储能系统容量高效合理配置问题,该文在分析高铁长大坡道的再生制动能量实测数据基础上,根据其功率分层的特性给出了混合储能系统的分段配置方案;考虑全域经济性能水平建立混合储能系统容量优化模型,针对传统优化算法迭代次数高、求解效率低等问题,利用Levy飞行产生初始解并在求解过程中不断记忆更新,给出了一种基于Levy飞行的改进模拟退火算法(LESA);最后,选取西成高铁秦岭北麓长大坡道路段,鄠邑(户县东)站牵引变电所实测数据进行算例仿真。结果表明,该方法可使混合储能系统在寿命期内回收大量再生制动能量,占牵引耗电量16.3%。High-speed railway trains will generate a large amount of regenerative braking energy and send it back to the traction network when they pass through the long ramp section,which will cause the voltage uplift of the traction network,harm traffic safety,and even cause economic losses to the railway enterprises.If this energy is reasonably recycled,it will be beneficial to reduce the energy consumption of high-speed rail,low-carbon transportation,energy conservation,and emission reduction,and achieve the‘3060’dual carbon target,which is more conducive to train safety.Studies have shown that it is a good method to recover regenerative braking energy by ground hybrid energy storage system,but it needs to be reasonably configured.Therefore,this paper presents a segmented configuration scheme and capacity optimization model for a hybrid energy storage system.The improved simulated annealing algorithm based on Levy flight(LESA)is used to optimize the capacity of the hybrid energy storage system on a long ramp of a high-speed railway.Firstly,the characteristics of regenerative braking power are analyzed from each and all day respectively.On this basis,considering the capacity requirements of the energy storage system,the energy is combined with the same type in chronological order to form the action segment,analyze the feasibility of the utilization of regenerative braking energy,and determine the recovery range.Accordingly,considering the respective characteristics of different media of the hybrid energy storage system,the energy recovery method with the threshold Pth as the boundary condition is formulated,the segmented configuration scheme of the hybrid energy storage system is established,and the economic indicators are calculated.Secondly,in the aspect of optimization algorithm,because the traditional simulated annealing algorithm(SA)has low efficiency,Levy flight is used to generate the initial solution,and it is constantly memorized and updated in the process of algorithm solution.An improved simulated annealin
