Energy Management Strategy with Energy Interaction and Configuration Optimization for the Tram's Hybrid Storage System

能量管理策略和容量配置是有轨电车混合储能动力系统设计的关键环节,其结果直接影响有轨电车的运行性能和经济效益。本文提出一种改进后带有能量交互状态的能量管理策略,根据实际车辆与线路要求,以重量最轻为优化目标进行容量配置优化,对比说明改进策略中电池与超级电容能量交互的优越性,并在实验平台上进行验证。仿真和实验表明,改进后的能量管理策略减轻了储能系统的重量,使储能系统在极端情况下能够正常运行。

Energy management strategy and sizing are the key steps of the design of tram's power system, and the results directly affect the operation characteristics and economic benefits. This paper proposes an improved energy management strategy with special state. Based on the fixed energy management strategy, a collaborative optimization of sizing with the requirement of tram and line data is carried out. The advantages are verified on the experimental platform. Simulation and experiment results indicate that the energy management strategy with special state reduces the sizing weight and guarantees the normal operation of tram in extreme cases.
