摘要发展纯电动公交对减少石油消耗量和改善城市环境具有十分重要的意义。以满足电动公交运营为前提,提出一种分时电价模式下能使电动公交经济运行的快速充电策略。首先求出所有满足时间和电量约束的电动公交可行车次链,并通过优化模型求出每条可行车次链的最优充电策略。其次建立电动公交最优车次链选择模型,通过该模型选择出满足约束且运行成本最低的可行车次链集。最后建立以充电负荷波动最小为优化目标的最优车次链夜间充电二次规划模型。以一条电动公交线路行车计划和充电计划编制为例,比较有序充电策略和无序充电策略的计算结果。结果表明,该文所提电动公交充电策略能起到削峰填谷、降低负荷波动的作用,并且充电成本更低,可作为电动公交制定行车计划和充电计划的参考。

Abstract：The development of pure electric bus is of great significance to reduce oil consumption and improve urban environment. On the premise of satisfying the operation of electric bus, this paper proposes a charging strategies which can make the electric bus run economically under the time-of-use price mode. Firstly, the all feasible vehicle chains of electric bus satisfying the time and electricity constraints are found out, and the optimal charging plan of the each feasible vehicle chain is solved by a optimization model. Secondly, the model of the optimal vehicle chains of electric bus is selected and established, through which the feasible vehicle chains sets which meets the constraints and has the lowest running cost is selected. At last, the optimal secondary planning model of night charging is established, which takes the minimum fluctuation of charging load as the optimization objective. Taking the running plan and charging plan formulation of an electric bus line as an example, the calculation results of orderly charging strategy and disordered charging strategy are compared. The results show that the electric bus charging strategy proposed in this paper can cut the peak and fill the valley and reduce the load fluctuation, and the charging cost is lower, it can be used as a reference for electric bus to make driving plan and charging plan.

Key words： Electric bus time of use (TOU) price quick charging charging strategy vehicle chain
