This study presents a new method for determining the harmonic contributions (HCs) of utility and consumer at the point of common coupling (PCC). The proposed method is based on a well‐known statistical signal processing technique, the so‐called complex independent component analysis (ICA). The complex ICA technique is applied to the harmonic voltage and current measured at the PCC to estimate the parameters of the Northon equivalent circuit model. Then, the HCs of utility and consumer are calculated through quantitative indices defined by the superposition method. The proposed method is robust against the background harmonic disturbances and works well in resonance condition. Moreover, the impact of consumer harmonic impedance is appropriately considered in calculations. The effectiveness of the proposed method is verified through the computer simulation and the real case study.
