【摘要】：针对目前电动汽车换电站(battery swapping station,BSS)规划决策中对"车-网"交互及其利益分散性考虑不足的问题,提出了一种基于合作博弈的电动汽车换电站优化配置方法。首先建立了同时计及充放电过程的BSS运行时序仿真模型;在此基础上,基于合作博弈理论,考虑电力系统安全运行及电动汽车用户的换电需求等方面约束,提出了以BSS和配电网公司(distribution company,DISCO)联盟收益最大为目标的换电站优化配置模型。该模型通过引入改进的DP指标(modified disruption propensity,MDP)分配机制对联盟收益进行合理分配,能够综合决策BSS的最佳电池配置数量、充电机数量以及各时刻的最优充放电功率。由于所建模型属于典型的混合整数非线性优化问题,采用M ATLAB中的YALM IP工具箱对此进行求解。最后,以某地区实际配电系统为例,验证了模型的可行性与有效性。
[Abstract]:In view of the problem of insufficient consideration of "vehicle-network" interaction and its benefit dispersion in the planning and decision of battery swapping station (BSS) for electric vehicle exchange power station at present. In this paper, a cooperative game based optimal configuration method for electric vehicle power station is proposed. Firstly, a simulation model of BSS running time sequence is established, which takes charge and discharge process into account at the same time. On this basis, based on the cooperative game theory, considering the power system safe operation and electric vehicle users' demand for electricity exchange and other aspects of constraints. BSS and distribution company are proposed. The optimal allocation model of power exchange power station based on the maximum profit of DISCO alliance. This model is based on the improved DP index (. Modified disruption propensity. MDP) allocation mechanism can make a rational allocation of alliance income, which can make a comprehensive decision on the optimal battery allocation of BSS. The number of chargers and the optimal charge and discharge power at each time. The model is a typical mixed integer nonlinear optimization problem. The YALM IP toolbox in M ATLAB is used to solve this problem. Finally, the feasibility and validity of the model are verified by taking the actual distribution system in a certain area as an example.
