Summary: | Abstract
Invasive and noninvasive are two common harmonic impedance estimation methods. Intrusive methods may affect the stable operation of the system. A harmonic impedance estimation method based on Kalman filter algorithm is proposed in this paper. The method adjusts the time interval of impedance estimation by selecting the frequency of sample. When the frequency of sample is high enough, it can be considered as real-time estimation of harmonic impedance. |
