A new algorithm for calculating utility harmonic impedance

•Estimation accuracy is improved when harmonic impedance ratio is about 1.•The idea is the weak correlation of harmonic current fluctuation.•This algorithm has a strong ability to resist non-stationary signal interference. In engineering, it is very valuable to estimate the utility harmonic impedanc...
