Lightweight Load Decomposition in Distribution Network Using Edge Computing
摘要
Abstract
The key problem in non-intrusive load decomposition is how to realize an accurate detection of load events of unidentified equipment in real time.Aimed at this problem,a cooperative computing system on the cloud-edge side is designed,which mines the behavior feature of load data collected on the edge side and hence realizes an effective de-composition of load signal.A lightweight K-means clustering algorithm is proposed considering the constraints of index-es such as the computing and storage resources of embedded controllers on the edge side together with power consump-tion.The instantaneous peak value,instantaneous power variation and harmonic components are selected as clustering features to realize the identification of load category locally.A lightweight particle swarm optimization algorithm is de-signed to realize the combination of the dynamic clustering algorithm and features including the transient power and har-monic components.The identification accuracy of the electric energy monitoring algorithm designed in this paper is high-er than 97.79%for the REDD shared data set.In addition,the non-invasive load monitoring of daily power consumption data for 313 households in one community is realized.关键词
