【摘要】 为优化能量管理策略，建立有轨电车模型，包括整车动力学模型、电池电路模型、电池寿命模型和超级电容器模型。基于庞特里亚金极大化原理(PMP),以列车运行成本(包括列车运行能耗成本和电池寿命成本)最小化为目标，同时考虑相关约束条件，对能量管理策略进行优化。基于列车实际运行工况，通过仿真进行对比，得出：与传统的阈值法能量管理策略相比，所提出的PMP能量管理策略能够节省13%的运行成本。更多还原

【Abstract】 In order to optimize the energy management strategy, a tram model was established, including vehicle dynamics model, battery circuit model, battery life model and supercapacitor model.Based on the Pontryagin maximal principle(PMP),the energy management strategy was optimized with the goal of minimizing the train operation cost(including the energy consumption cost and battery life cost of the train operation) and considering the relevant constraints.Based on the actual running conditions of trains, the simulation results showed that the proposed PMP energy management strategy could save 13% of the operation cost compared with the traditional threshold method energy management strategy.更多还原
