The lecture will be based on the research done in the topic of Impedance-based stability analysis of power electronics systems, under the NTNU-SJTU cooperation from 2012 until now. It will start with the basics of the Impedance-based stability analysis method, going from impedance modeling in the dq domain, moving towards the motivations for the emergence of the sequence domain impedance with its modified sequence domain (MSD) definition and the proposal of an equivalent SISO impedance modeling. The use of the Nyquist criterion in its classical and generalized forms will be discussed in the light of the different properties of the impedance models (MIMO, SISO). The application of the impedance-based method in the stability study of network of impedances, impedance aggregation and identification techniques and stability-oriented network planning will be elaborated and discussed. These methods will be expounded through various application examples in the realm of renewable energy integration through power electronic interfaces. The most recent developments in the topic of impedance will be introduced, to point out the foreseen new directions where research efforts are needed.
