dc.description.abstractRepresentations of power systems by frequency dependent impedance equivalents is an emerging technique in dynamic analyses of power systems including power electronic converters. The technique has been applied for decades in DC-power systems, and it has been recently adopted to map the impedances in AC systems. In the impedance-based stability analysis, the system is split into a source and load subsystem, both of which are represented by their respective frequency-dependent Norton and Thevenin equivalents. These equivalents can be obtained from analytic calculations, from numeric simulations, or from laboratory setup measurements. This paper will present a comparison of analysis and simulation-based techniques for obtaining the impedance equivalents. Different approaches for extraction of impedance equivalents are found in the literature but a rigorous comparison among the methodologies is still missing. Such comparison is relevant since non validated/verified impedance equivalents and extraction methods can lead to misleading conclusions. This work is attempting to bridge this gap by presenting a comparison of different simulation-based extraction methods and an analytical one.nb_NO
