Abstract

A methodology for obtaining dynamic equivalents of a detailed power system is presented. Two types of reduced order models are developed: a model describing the local behaviour in each area and a model describing the global behaviour between areas. The centre-of-area variables developed for the global model describe equivalent aggregate machines and clarify the nature of the aggregate models. A ten-machine example illustrates the theory.
