摘　　要：随着电动汽车(EVs)保有量逐年增加,充电需求日益增大,短时间内大规模EVs集中充电不仅会给电网稳定运行带来风险和负担,还会造成路网交通拥堵。为了缓解上述问题,提出一种兼顾配电网、路网和车主三方利益的“车-路-网”三层充电优化方法。通过三层优化模型的相互传递与配合,对配电网的等效负荷方差和有功网损、路网的通畅情况、车主的充电总成本进行协调优化。以杭州市某区域路网为例,结合IEEE-33节点配电网系统进行仿真。通过三层充电优化,系统等效负荷方差降低72.82%,有功网损降低83.41%,车主充电总成本减少8.89%。仿真结果表明,所提优化方法能够合理安排EVs充电,可以在平抑负荷波动和降低有功网损的同时,缓解路网拥堵和降低车主充电总成本。As the number of electric vehicles(EVs)increases year by year,the demand for charging is increasing,and the large-scale centralized charging of EVs in a short period of time will bring risks and burdens to the stable operation of the power grid and cause traffic congestion on the road network.In order to alleviate the above problems,a method of three-layer charging optimization of"vehicle-road-network"is proposed,which takes into account the interests of the distribution grid,road network and vehicle owners.The equivalent load variance and active network loss of the distribution network,the smoothness of the road network,and the total charging cost of the vehicle owner are coordinated and optimized by means of the mutual transfer and cooperation of the three-layer optimization model.Taking the road network of a certain area in Hangzhou as an example,the simulation is carried out by combining with the distribution network system of the IEEE-33 node.After the three-layer charging optimization,the system equivalent load variance is reduced by 72.82%,the active network loss is reduced by 83.41%,and the total charging cost for vehicle owners is reduced by 8.89%.The simulation results show that the proposed optimization method can arrange the EVs charging reasonably,which can smooth the load fluctuation and reduce the active network loss while alleviating the road network congestion and reducing the total cost of charging for vehicle owners.
