Abstract

This paper presents the bifurcation analysis of a detailed power system model composed of an aggregated induction motor and impedance load supplied by an under-load tap-changer transformer and an equivalent generator and transmission system. Different modeling levels with their respective differential-algebraic equations are studied, to determine the minimum dynamic model of the system that captures the most relevant features needed for bifurcation studies of power systems. An aggregated model of a realistic load is used to illustrate the ideas presented throughout the paper.
