    摘 要:为了直观评估燃料电池有轨电车混合动力系统的氢耗量和燃料电池寿命,并提升系统的经济性与稳定性,构建了燃料电池寿命衰减模型与系统氢耗模型,将其整合为混合动力系统的单目标价值损失评价函数,并采用人工旅鼠算法(ALA)对目标函数进行优化。将优化结果与状态机策略、等效氢耗最小策略的优化结果进行比较,结果表明:基于 ALA 的混合系统能量管理策略在控制氢耗增幅的同时显著降低燃料电池寿命衰减速率,从而提升了有轨电车的经济性与耐久性。

    Abstract: To intuitively evaluate the hydrogen consumption and fuel cell lifespan of a fuel cell tram hybrid power system and enhance its economic efficiency and stability, thus this study establishes life attenuation model and system hydrogen consumption model of the fuel cell,then integrates into the single-objective value loss evaluation function of the hybrid power system and artificial lemmage algorithm(ALA) is adopted to optimize the objective function. The optimization results were compared with those of the state machine strategy and the strategy of minimizing equivalent hydrogen consumption. The results show that the energy management strategy of the hybrid system based on ALA significantly reduces the rate of life degradation of fuel cells while controlling the increase of hydrogen consumption, thereby improving the economy and durability of trams.
    Key words: fuel cell; hybrid power system; artificial lemmage algorithm; value loss; energy management strategie; tram
