摘要:

由于电动汽车车主选择充电站具有较大的随机性，使得各充电站的利用率存在较大的差异，从而造成整个电网的负荷失衡，影响配电网的稳定性和安全性。针对上述问题，将行驶路程最近、时间最短、充电站时间利用率偏差最小和功率利用率偏差最小作为优化目标，建立了电动汽车充电路径多目标优化调度模型。在对该模型进行求解的过程中，提出了基于细菌趋化的改进粒子群算法进行求解。仿真结果表明，采用该算法后，电动汽车车主可以根据区域内充电站的利用率情况有目的选择充电站，实现均衡化充电站利用率的目的。

Abstract:

The utilization of every charging station varies greatly because the Electric Vehicle (EV) owners have great randomicity for choosing charging station, which causes the load imbalance of the whole power grid and affects the stability and security of the power grid. In view of the problem, minimum driving distance, minimum time and minimum deviation of time utilization rate and power utilization rate for charging station as optimization objectives, multi-objective optimal scheduling model of EVs for charging route is built. An improved Particle Swarm Optimization Algorithm based on Bacterial Chemotaxis (PSOBC) is proposed in order to solve the model. The simulation results show that the EV owners can purposefully choose charging stations according to the utilization of the charging stations in the area after adopting the proposed algorithm, which realizes the purpose of utilization equalization for charging stations. This work is supported by Industry-Academy-Research Cooperation Project of Jiangsu Province (No. BY2016026-01) and Natural Science Research Project in Universities of Jiangsu Province (No. 16KJB480006).
