Study on the Estimation of Utility Harmonic Impedance Based on Minimum Norm of Impedance Difference

Study on the Estimation of Utility Harmonic Impedance Based on Minimum Norm of Impedance Difference

The existing methods for estimating harmonic impedance usually assume that harmonic impedance is constant in a measurement period. However, for a variety of practical reasons, such as the load change of power grid, utility harmonic impedance may be changed. So a reasonable hypothesis is that utility...
