基于碳排放的插电式混合动力公交车能量管理策略

Plug-in Hybrid Electric Buses Energy Management Strategies Based on Carbon Emissions

文章以插电式混合动力公交车(PHEB)为研究对象,建立了当量碳排放模型。基于庞特里亚金极小值原理(PMP),考虑车辆运行的能耗与当量碳排放,提出了一种全局最优的能量管理策略,并利用打靶法对目标函数进行求解。通过仿真分析,得到了最佳功率分配和最优综合成本:百公里天然气消耗10.33 m^(3),电耗49.17 kWh,当量碳排放53.56 kgCO_(2)e,百公里综合成本104.33元。

Taking plug-in hybrid electric buses(PHEB)as the research object,this paper establishes a PHEV equivalent carbon emission model.Based on the pontriagin’s minimum principle(PMP),considering the energy consumption and equivalent carbon emissions of vehicle operation,a global optimal energy management strategy is proposed,and the objective function is solved by the target method.Through simulation analysis,the optimal power distribution and optimal compre-hensive cost are obtained:natural gas consumption per 100 km is 10.33 m^(3),electricity consumption is 49.17 kWh,equivalent carbon emissions are 53.56 kgCO_(2)e,and the comprehensive cost per 100 km is￥104.33.
