摘要
依据实际电网运行和交通运行情况,提出了基于双网络结构的电动汽车充换电网络的二次分区规划方法。鉴于电池集中充电站同时具备电网负荷和充换电网络上级供应源的2种性质,以其为核心构建了电力网络和充换电网络相连接的双网络结构。在此基础上,以电源辐射面积进行一次分区,并通过交通负荷网格化预测一次分区负荷;其次,根据电压偏移情况对一次分区内电池集中充电站选址;然后,基于一次分区结果根据交通情况进行二次分区,并利用改进粒子群算法在二次分区内对电动汽车换电站选址;最后,通过某城市充换电网络规划实例验证了这种方法的合理性。
Based on the dual network structure, a secondary partition planning method is proposed for the electric vehicle charging and discharging network according to the grid operation and traffic situation. In view of the dual natures of the centralized battery charging stations, which is both the load of electric grid and the power supply for charging and discharging network, a dual network is established to connect the power network and the charging and discharging network. Preliminary partition is made according to the power service area and the load of the preliminary partition is predicted through traffic load gridding. Then, site selection is made for the centralized battery charging station according to voltage offset condition. Finally, secondary partition is made according to the traffic situation. The sites of discharging stations are chosen in the secondary partition by using the improved PSO algorithm. The rationality of this method has been proved through the charging and discharging network planning in one city.
