基于低秩模型的电力状态数据异常检测
Low-Rank Representation for Outliers Detection in Power State Estimation
摘要
Abstract
Smart grid plays a critical role in national production. The stability and security of smart grid is essentially impor-tant. As a result, it is significant to detect the bad and malicious data from daily observations. This paper proposes a novel outlier detection method based on low-rank representation. Specifically, the observation is decomposed into two parts:a low-rank part for clean data and a sparse part for outliers. In addition, this paper deploys ALM(Augmented Lagrange Mul-tiplier)to optimize the objective. Extensive experiments on two popular benchmarks verify the advantages of the pro-posed method.关键词
