The invention discloses an electric vehicle aggregation scheduling method considering battery loss cost, which comprises the following steps of: aggregating electric vehicles according to initial data, putting the same type of electric vehicles as a polymer, and establishing an aggregation model according to different types of electric vehicles in sequence; establishing a battery degradation loss model according to the relationship between the deep charging and discharging times and the actual capacity of the lithium battery; in consideration of the battery loss anxiety cost of a vehicle owner, establishing an electric vehicle user willingness model; establishing a vehicle network interactive scheduling model with minimum user battery loss and maximum charging income as targets; establishing an expected value optimization model about the charging cost of the user; in an MATLAB 2022b environment, a CPLEX solver is used for solving the model; according to the method, the electric vehicles are aggregated, the battery loss of the electric vehicles is considered, the uncertainty of user charging anxiety is analyzed and modeled, load pressure reduction in the peak period of a power grid is achieved, and the solving efficiency is greatly improved.

    本发明公开一种计及电池损耗成本的电动汽车聚合调度方法,包括:根据初始数据对电动汽车进行聚合,将同种电动汽车放在一类,作为一个聚合体,再依次根据电动汽车种类的不同建立聚合模型;根据锂电池的深度充放电次数和实际容量关系建立电池退化损耗模型;考虑到车主的电池损耗焦虑成本,建立电动汽车用户意愿模型;建立以用户电池损耗最小和充电收益最大为目标的车网互动调度模型;建立一个关于用户充电成本的期望值优化模型;在MATLAB 2022b环境下利用CPLEX求解器对模型进行求解;本发明将电动汽车进行聚合并考虑了电动汽车的电池损耗,并对用户充电焦虑的不确定性进行了分析建模,实现对电网高峰时期负荷减压,极大提升了求解效率。
