Abstract

A time-scale separation procedure is outlined and applied to a three machine interconnected power system modeled with flux linkage and voltage regulator dynamics. Partial models such as the electromechanical model and single machine-infinite bus model are used to identify the slow and fast states of the systems. Linear simulation results in two- and four-time-scales demonstrate the potential applicability of the singular perturbation approach to long-term dynamic studies of power systems.
