An Integrated Method for Generating VSCs’ Periodical Steady-state Conditions and HSS-based Impedance Model

Abstract

An integrated method for generating the system’s
periodical steady-state (PSS) conditions and the harmonic-statespace (HSS)-based impedance model is presented, referred to as
the automatic-model-generation (AMG) method. This method is
efficient for parametric impedance-based stability analysis, since it
can precisely take the varying PSS into account and the presented
algorithm can be readily implemented by the frequency-domain iteration. Application of this AMG method to the impedance acquisition and stability analysis of a single-phase grid-tied voltage-sourceconverter (VSC) along with experimental verifications is presented
as an example. The presented results demonstrate how the AMG
method can facilitate parametric stability assessments (e.g., under
varying control parameters) in an efficient and accurate manner
