基于多种群遗传改进FCM的无功/电压控制分区

Network partitioning for reactive / voltage control based on multigroup improved FCM

为充分考虑网架结构和各无功源的共同作用,提出一种新的电气距离计算方法。依据各节点间无功电压摄动变化关系和节点关联矩阵将系统各节点映射到一个n维空间中,在节点间构建一种新的电气距离。针对一般无功/电压控制分区方法不稳定的问题,提出多种群遗传算法改进模糊C均值聚类的无功/电压控制分区算法,然后将其分别运用于IEEE 30和118节点算例,并把分区结果与文献结论进行分析和比较,验证了该算法的准确性和有效性。

A new method to calculate the electrical distance is proposed,which fully considers the combined effect of network structure and various sources of reactive power. According to the relationship between reactive voltage pertur- bation and weight matrix to each node in the system will be mapped to an n-dimensional space, and then constructs a new electrical spatial distance between nodes. With regard to the instability features of reactive power and voltage con- trol network partitioning, this article proposed the multigroup improved FCM as reactive/voltage control partitioning al- gorithm and applied to the IEEE 30-bus and 118-bus system. At last, the partitioning result is analyzed in detail and compared with the other algorithm to show the accuracy and feasibility of the proposed algorithm.
