- Abstract:
- The paper deals with the LTI/LTV power system models and their experimental verification. The frequency dependent system impedance is used for power system harmonics studies. As a voltage/current power system transfer function it explains well harmonics related phenomena observable in real systems. With very accurate impedance measurements power system nonlinearity can be observed. The nonlinearity manifest as system time-variance for which LTV (linear time varying) model can be used. New model improves power system description. The problems of such the model identification and verification are discussed in the paper.
