【摘要】：提出了一种考虑配网潮流约束的高速公路快速充电站校正规划方法。利用电动汽车充电需求预测模型得到高速公路上电动汽车充电需求点的时空分布信息;在此基础上,基于共享型最近邻居聚类算法构建高速公路快速充电站的选址模型,以确定快速充电站的站址方案;进而基于排队论理论和充电需求的时空分布构建快速充电站定容模型,以确定快速充电站的容量配置。对该规划方案下配网潮流约束进行判断,若不满足,则利用所提出的校正原则对规划方案进行修正,直到满足配网的潮流约束为止,以得到最终的快速充电站规划方案。通过典型算例验证了所提规划方法的有效性。
[Abstract]:In this paper, a calibration planning method for expressway rapid charging station considering the power flow constraints of distribution network is proposed, and the time and space distribution information of charging demand point of electric vehicle on expressway is obtained by using the electric vehicle charging demand prediction model. On this basis, the location model of expressway rapid charging station is constructed based on shared nearest neighbor clustering algorithm to determine the location scheme of rapid charging station. Then, based on the queuing theory and the space-time distribution of charging demand, the fixed volume model of the rapid charging station is constructed to determine the capacity configuration of the rapid charging station, and the power flow constraints of the distribution network under the planning scheme are judged if they are not satisfied. Then the proposed correction principle is used to modify the planning scheme until the power flow constraints of the distribution network are satisfied. In order to obtain the final rapid charging station planning scheme, the effectiveness of the proposed planning method is verified by a typical example.
