Abstract
In view of the shortcomings of the current electricity theft detection model,such as requiring a large number of samples,complex training process,and the detection performance needs to be improved,a detection model based on local matrix reconstruction is proposed.The principal component analysis is introduced to analyze the distribution characteristics of the differences between adjacent data samples;the Euclidean distance and data distribution characteristics are used to detect the differences between different power consumption modes;the local outlier score is introduced to determine the power theft samples.The residential power load data provided by a power company is used for experimental analysis,and the results show that the area under the ROC curve of the proposed model is 0.846 3,which has a relatively stable detection threshold and stronger robustness,and has a certain reference for the electricity theft detection and evaluation of distribution network.关键词
