摘　　要：针对电动汽车充放储一体站并网带来的电压问题以及电压控制分区方法的不足,提出一种一体站并网的多级阶梯电压控制分区方法。在定义无功源控制的电气距离和评价分区质量的加权社团结构(community structure,CS)多目标模块度指标的基础上,多级阶梯电压控制分区方法分降维聚类、分裂凝聚、还原调整3级进行最优分区。在分区中结合电网运行状态,对一体站功能行为进行多场景优化,根据场景概率计算无功期望。算例采用IEEE39节点系统对一体站并网进行电压控制分区,验证了方法的合理性和正定性,反映出一体站并网对分区带来的影响;同时采用IEEE118节点系统进行电压控制分区,验证了方法应用在大系统中的合理性和高效性。According to the voltage problems of the electric vehicles integrated station connected to grid, a multistage ladder voltage control partitioning method was developed in this paper for the defects of the clustering. On the basis of an electrical definition to measure the var sources and a weighted community structure multi-objective modularity index to evaluate partitioning quality, the multistage ladder partitioning method is used for the optimal partition, which consists of three stages, dimension reduction clustering, split agglomeration, refining. Combined with the power grid operation state in the partition, the characteristics of the integrated station were optimized with multi-scenario and using scenario probability calculating expected reactive power. The IEEE 39 bus system verifies the reasonableness and the correctness of the partitioning method, and reflects the partitioning problems of the integrated station connected to grid. At the same time, the method has high computational efficiency when applied to IEEE 118 bus system.
