Generalized multiport representation of power systems using ABCD parameters for harmonic stability analysis

Abstract

This paper introduces a complete modeling framework for harmonic stability assessment starting from ABCD parameters. It does so by presenting the theoretical foundations for modeling power system components in the ABCD domain, developing adequate interconnection methods for the components, as well as determining the ABCD parameters from any port in the system. The paper also illustrates how the resulting ABCD component models can conveniently be used for a stability analysis of an entire system, consisting of both active and passive components.
