针对传统分区方法电气距离定义的缺点,提出一种新的电气距离即空间电气距离。依据系统中各节点之间无功电压变化关系,将系统各节点映射到一个多维空间中,节点之间的空间距离便是其电气距离,依据此距离将各节点进行归类,从而把无功电压控制分区问题转化为数学上的空间聚类问题。针对无功电压控制分区的特点并借鉴聚类算法,提出免疫—中心点聚类的无功电压控制分区算法并将其运用于IEEE118节点系统,对分区结果进行分析并与其他算法结果比较,验证所提出的算法的准确性和可行性。
In view of the shortcomings of the traditional definition of the electrical distance of the partition method, a new electrical distance, ie, the electrical distance in space, is proposed. According to the variation of reactive voltage between nodes in the system, each node in the system is mapped into a multi-dimensional space. The spatial distance between nodes is its electrical distance. Based on this distance, each node is classified, Voltage control zoning problem into mathematical space clustering problem. Aiming at the characteristics of reactive voltage control zone and referring to the clustering algorithm, a reactive-voltage control zone algorithm based on immune-center point clustering is proposed and applied to the IEEE118 node system. The partition results are analyzed and compared with other algorithms to verify The proposed algorithm is accurate and feasible.
