Harmonic Source Modeling Method Based on VMD-DBSCAN

Based on the existing research, this paper proposes a harmonic source modeling method based on VMD-DBSCAN for existing household multi-state harmonic source loads. First, this paper uses VMD-DBSCAN to identify the state of the harmonic source load, and then combines the identified state with the equivalent impedance parameters of the load to establish a harmonic source model. Finally, the simulation model data and private data set data are used to analyze and verify the proposed method. The experimental results show that the proposed method has the advantages of high identification accuracy and modeling accuracy.
