摘要
功率融通型轨道交通“网-源-储-车”协同供能系统在原牵引供电系统结构基础上增设了新能源系统、储能系统及功率融通装置。针对该新型供电结构,本文提出一种基于动态规划的自适应能量管理策略以提升系统的综合能效水平。首先建立能量管理过程的多目标优化数学模型,在此基础上通过动态规划算法,经过策略评估、优化及迭代等操作得到最优动作策略。仿真结果表明,该能量管理策略可以有效适应电力机车的各类运行场景,并实现储能系统及新能源系统与牵引供电系统的协同高效运行,有效提升了再生制动能量和新能源能量的利用效率,降低了电力机车的牵引能耗和对牵引网的功率冲击。
The power integration type rail transit"network-source-storage vehicle"collaborative energy supply system has added new energy system,energy storage system,and power integration devices on the basis of the original traction power supply system structure.The paper puts forward an adaptive energy management strategy based on dynamic planing to improve the comprehensive energy efficiency level of the system for this new power supply structure.Firstly,establish a multi-objective optimization mathematical model for the energy management process,and on the basis of this,use dynamic planing algorithms to obtain the optimal action strategy through strategy evaluation,optimization,and iteration.The simulation results show that the energy management strategy can effectively adapt to various operating scenarios of electric locomotives,and achieve efficient operation of the energy storage system,new energy system,and traction power supply system,effectively improving the utilization efficiency of regenerative braking energy and new source energy,reducing the traction energy consumption of electric locomotives and the power impact on the traction network.
