基于VMD和PSO-SVM的非侵入式负荷识别方法
Non-intrusive load identification method based on VMD and PSO-SVM
摘要
Abstract
Non-intrusive load monitoring is one of the important technologies of intelligent power consumption,a-mong which load decomposition and identification is an important link to realize the technology.In view of the ad-vantage of variational mode decomposition(VMD)in signal processing,a load identification algorithm based on variational mode decomposition and fast independent component analysis(VMD-FastICA)and variational mode de-camposition-entropy-particle swanm optimization fo optimizing support vector machines(VMD-Entropy-PSOSVM)is proposed.The total load power signal is decomposed using VMD to obtain multiple intrinsic mode functions(IMF),and then,the IMF is reconstructed based on the cliff criterion and singular value decomposition to virtual-ize single-channel blind source separation into multi-channel blind source separation into fast independent compo-nent analysis(FastICA)for load signal separation.Then,the energy and energy entropy of the modal components of the decomposed load waveform are obtained,and the multi-dimensional feature matrix input is constructed to es-tablish a particle swarm optimization-support vector machine particle swarm optimization for optimizing support vec-tor machines(PSO-SVM)for classification and identification of the load.The experimental algorithm is simulated using the reduced electricity dataset(REDD),and it is verified that the algorithm has better results in both decom-position and recognition compared to other algorithms.关键词
