Description
Summary:The non-intrusive load identification method can judge the type and working situation of the electrical load without interfering with the user’s electricity consumption, which is an important part of smart grid technology. In this paper, a load identification method based on variational modal decomposition algorithm (VMD) is proposed, which can effectively identify different types of electrical loads. The effectiveness of VMD algorithm in the field of load identification is verified by conducting load recognition experiments. After optimizing the algorithm parameters, the Feature library membership threshold was tested and debugged, and finally a good load identification effect was obtained, which can be used as a means of identifying electricity load in urban management.
