Harmonic Impedance Calculation Method Based on Data Fusion

Starting from the existing independent component method and binary linear regression method, the advantages and disadvantages of the two methods in harmonic impedance calculation are explored, and a harmonic impedance calculation method based on data fusion is proposed. This method maintains high accuracy when the background harmonic is unstable and the source signals on both sides of PCC point are correlated. The accuracy and effectiveness of the proposed method are verified by simulation experiments, which provides theoretical guidance for the subsequent harmonic control work.
