Energy management strategy of hybrid tram based on improved dynamic programming algorithm

针对混合动力有轨电车的能量管理,文章在建立电池和超级电容混合储能系统的能量流动模型的基础上,以电池和超级电容的荷电状态为状态变量,提出了一种基于改进动态规划算法的能量管理策略,并以某实际线路的有轨电车为例对该能量管理策略进行了仿真验证。仿真结果证实了该能量管理策略的有效性。

For the energy management of hybrid tram,on the basis of establishing the energy flow model of the hybrid energy storage system with battery and ultracapacitor,taking the state of charge of battery and ultracapacitor as the state variable,this paper proposes an energy management strategy based on the improved dynamic programming algorithm,and takes the trams of an actual line as an example to verify the energy management strategy.The simulation results verify the effectiveness of the energy management strategy.
