摘　　要：随着高比例、大规模分布式光伏并网以及电动汽车的普及,如何发挥电动汽车灵活性、实现配电网分布式光伏与本地电动汽车负荷灵活性资源的友好协调是当前需要解决的重要问题。为此,提出了考虑电动汽车与分布式光伏协同的配电网集群划分与运行策略。首先,建立电动汽车可调充电功率灵活性聚合模型,提出基于Louvain算法的改进模块度指标配电网分布式集群划分方法;其次,基于历史数据信息生成电动汽车多时间尺度充电场景,提出考虑电动汽车充电灵活性的分布式集群协同优化模型;最后,采用同步交替方向乘子法(synchronous alternating direction multiplier method,SADMM)实现各集群优化模型的分布式求解。仿真结果表明,利用电动汽车充电灵活性参与配电网协同运行可有效提高分布式光伏利用率,并且在满足电动汽车用户充电需求的同时保证了配电网电压运行安全。With the high proportion and large-scale distributed photovoltaic grid-connection and the popularity of electric vehicles,how to exert the flexibility of electric vehicles to coordinate friendly distributed photovoltaic and local electric vehicle load flexibility resources in the distribution network is the important issue that needs to be solved.Therefore,distribution network cluster partitioning and operation strategy are proposed considering the collaboration between electric vehicles and distributed photovoltaic.Firstly,an adjustable charging power and flexible aggregation model of electric vehicles is established,and a distributed network cluster partitioning method based on Louvain algorithm with improved modularity index is proposed.Secondly,based on historical data,multi-time scale charging scenarios of electric vehicles are generated,and a distributed cluster collaborative optimization model is proposed considering charging flexibility of electric vehicles.Finally,the algorithm of synchronous alternating direction multiplier method(SADMM)is used to solve distributedly for optimal models of all clusters.The simulation results show that the use of electric vehicles charging flexibility to participate in the collaborative operation of the distribution network can effectively improve the utilization rate of distributed photovoltaic,and ensure the safety of the voltage operation of the distribution network while meeting the charging needs of electric vehicles users.
