摘要
负荷建模的最大困难在于负荷的随机性和分散性,而基于聚类方法的负荷特性分类是解决这一问题的有效途径。将系统聚类法中的Ward法引入到负荷特性分类研究中,并给出了该方法在一个区域电网中的应用实例。结果验证了该方法应用于负荷特性分类研究的可行性和有效性,聚类结果合理、准确、客观,表明该方法具有较好的工程应用前景。
Randomness and dispersivity of the load are the biggest difficulty of load modeling, and an effective solution to this problem is load characteristics classification based on clustering method. Ward method belonging to system clustering is introduced to the study of load characteristics classification ,and an application example of the method in regional power system is given. The results proves that the proposed method which is applied to study on classification of load characteristics is feasible and effective. The clustering results have the features of rationality, reasonable, accuracy, objectivity, which shows that the method has good prospect in engineering application.
