The invention relates to the technical field of bus charging, in particular to a bus fast charging station ordered charging method based on a data driving energy efficiency model. The method comprises the following steps: firstly, determining an electric quantity demand meeting bus route operation, and then establishing a relationship between charging energy conversion efficiency and charging power actually charged by a vehicle-mounted energy storage system; a nonlinear optimization objective function model is established by taking the minimum actual electricity consumption of a charging station in one day or the minimum actual electricity charge of the charging station in one day as an objective function, considering the charging energy conversion efficiency and taking the electric bus line operation electricity demand and the electric bus charging time continuity as constraint conditions; converting the nonlinear optimization objective function model into a mixed integer convex programming problem by using piecewise linearization, and solving the mixed integer convex programming problem to obtain an optimal charging plan; according to the scheme, the energy conversion efficiency of charging can be further improved on the basis of traditional ordered charging, the electricity utilization cost of a charging station operator and the charging cost of the electric bus are reduced, and the economical efficiency is improved.

    本发明涉及公交车充电技术领域,具体涉及基于数据驱动能量效率模型的公交车快充站有序充电方法;首先确定满足公交线路运行的电量需求,随后建立充电能量转换效率与车载储能系统实际充入的充电功率之间的关系;以一天中充电站的实际用电量最小或一天之中充电站的实际电费最少为目标函数,其中考虑充电能量转换效率,以电动公交车线路运行电量需求、电动公交车充电时间连续性为约束条件建立非线性的优化目标函数模型,随后使用分段线性化将非线性的优化目标函数模型转换为混合整数凸规划问题,求解混合整数凸规划问题得到最优的充电计划;本方案能够在传统有序充电的基础上进一步提高充电的能量转换效率,降低充电站运营商的用电成本和电动公交车的充电成本,提高经济性。
