摘　　要：针对燃料电池/锂电池/超级电容混合储能有轨电车在动态负载、启停循环、怠速循环、大功率运行时质子交换膜(PEM)燃料电池寿命衰减情况,提出Pontryagin极小值原理(PMP)与耐久性结合的能量管理策略。通过启停控制策略控制燃料电池的启动与停止,有效降低燃料电池启动次数;利用储能系统总体氢气消耗为经济性代价,燃料电池性能衰退指数为耐久性代价,构建联合代价函数;在满足期望条件下,实现协态变量随荷电状态实时变化的在线适应;将所提策略与传统极小值策略和状态机策略进行仿真对比。结果表明:城市循环工况中所提策略较于传统Pontryagin策略燃料电池峰值电流降低了33.2%,氢气消耗下降了12.50%;郊区循环工况中所提策略较传统Pontryagin策略峰值电流降低了21.88%,氢气消耗下降了40.39%。所提管理策略在不同工况下均有良好的适应能力,解决了传统PMP只能离线应用的缺点,将启停次数控制在较低水平,具有延寿燃料电池的能力。Aiming at the life decay of proton exchange membrane(PEM)fuel cells in fuel cell/Li battery/supercapacitor hybrid energy storage streetcars during dynamic loading,start-stop cycle,idling cycle,and highpower operation,an energy management strategy combining the Pontryagin's minimum principle(PMP)of very small value and durability was proposed.The start-stop control strategy controlled the start and stop of the fuel cell,effectively reducing the number of fuel cell starts.The joint cost function was constructed using the overall hydrogen consumption of the energy storage system as the economic cost and the fuel cell performance degradation index as the durability cost.The online adaptation of the covariance variable with the real-time change of charge state was realized under satisfying the desired conditions.The proposed strategy was simulated and compared with the traditional minimal value strategy and state machine strategy.The results show that the proposed strategy under the urban cycling condition reduces the peak current by 33.2%and hydrogen consumption by 12.50%compared with the traditional Pontryagin strategy fuel cell;the proposed strategy under the suburban cycling condition reduces the peak current by 21.88%and hydrogen consumption by 40.39%compared with the traditional Pontryagin strategy.The proposed management strategy has good adaptability under different working conditions,solves the shortcomings of traditional PMP that can only be applied offline,controls the number of start-stop at a low level,and has the ability to extend the life of the fuel cell.
