Study on an approach to the secondary voltage control partition based on mode clustering

In order to solve the problems of the secondary voltage control partition effectively, an approach to partition based on the visual self - organizing feature mapping network clustering technique was presented. Based on the characteristics, such as topology holding, information bond andhigh- dimension data vector quantization, which the self- organizing feature mapping network has, the visual topology mapping pattern used for partitioning system voltage was set up meanwhile the secondary voltage control partition was carried out basing on the topology mapping image, after that It is presented that entropy is used to search dominant node as measuring variable. The approach to partition combined with node voltage, phase angle and sensitivity etc, in favor of control decoupling between partitions.
