一种基于模糊聚类分析的电压分区方法探讨

分析了传统无功电压分区中采用的电气距离不足之处,考虑了多个节点之间相互影响的作用,并将这种影响映射成为一个多维的线性空间,在该空间中采用了新的空间距离进行无功电压分区。在此基础上,将电网分区问题转换成高维空间中的聚类问题,并采用模糊聚类算法得到动态聚类图,引入F-统计量来选择最佳分类数。最后,以IEEE39节点系统为例进行电压聚类分区,得到了较好的分区效果。

Probing into a Method for Power Network Partitioning Based on Clustering Analysis

The shortcoming of traditional definition of electrical distance in power network partitioning is discussed. The effect between power network load nodes is considered, the effect is transformed into a high-dimension space. By this way,the problem of power network portioning can be transformed into a clustering analysis problem in a high-dimension space, fuzzy clustering arithmetic is used to get the dynamic clustering plot.After calculating the statistic F, we can get the final optimal clustering. Finally t...
