A Noninvasive Method to Estimate the Variable Utility Harmonic Impedance
IEEE Transactions on Power Delivery, 2023The existing noninvasive methods estimating utility harmonic impedance are usually based on the assumption that the impedance is constant during a time interval of concern.

A Method for Estimating the Utility Harmonic Impedance Based on Semiparametric Estimation
IEEE Transactions on Instrumentation and Measurement, 2021Estimating the utility harmonic impedance of a point of common coupling (PCC) is of significance to harmonic emission level evaluation. The most existing methods for estimating the utility harmonic impedance are based on the assumptions that the ...
