摘要
根据聚类的定义构造了多维空间的样本集,计算发电机节点对负荷节点的控制灵敏度和各负荷节点间的欧氏距离,利用聚类分析中的最短距离法对电力系统进行分区。在确定了有效分区数的取值范围后,用熵的香农函数和Sugeno-Yasukaw准则确定最佳分区数与分区有效性,并对IEEE39节点系统进行了分区验证。
The paper construct the specimen of multi-dimensional space based on the definition of clustering, calculate the generator control sensitive to load and the Eulerian distance, partition the power system by the shortest distance method of clustering analysis. After the range of area num-ber is determined, the optimal area number and its validity is decided by Shannon function of entropy and Sugeno-Yasukaw rule. A case of IEEE 39-bus system is presented to verify the method.
