摘　　要：首先基于静态能量函数法,构建了一种改进后的支路无功势能数学模型。从支路能量信息出发,结合复杂网络理论,提出了量化无功势能的线路权重系数。其次,针对电压控制问题,建立了基于支路无功势能的电网加权拓扑模型。然后,利用社区网挖掘的分区理论,采用最大线路介数法对该加权拓扑网络进行电压区域划分。最后,通过IEEE30节点系统对此方法进行仿真,并将所得分区结果与其他方法进行分析比较,结果表明该方法有效、可行。Based on the static energy function, an improved mathematical model of branch reactive potential energy is constructed. Started from branch energy information and combined with complex network theory, a line-weighted factor is proposed to quantify the reactive potential energy. Secondly, according to the voltage control problems, a weighted grid topology model based on branch reactive potential energy is established. Then on the basis of community network mining partition theory, the weighted topology network is partitioned with the maximum number of line betweenness method. At last, the simulation results of this method on IEEE-30 bus system and the comparing results with other methods demonstrate its validity and feasibility.
