Study on significant modes in identified model for a large electric power system

The wide-spread deployment of phasor measurement units (PMUs) in the large electric power system (EPS) will allow the implementation of wide area control algorithms effectively through the use of identified models. However, this would be possible only if, such system is accurately represented by its equivalence. The work in this paper addresses equivalent model representation using model identification techniques. The identified model with speed difference between the generators in the system as output signal is shown to retain significant oscillatory modes of the actual large EPS.
