This paper studies the structure features of the collected power consumers' power consumption data, in which the 96 measured data points indicating a single user's power consumption curve of a day. The 96 measured data points are taken as 96 variables for analysis. The dimensionality of original data is reduced by principal component analysis (PCA), and then the K-means algorithm is employed to cluster...
