Research on decentralized control of an electric power system is important for stabilizing control problems. In particular, since an electric power system is a large‐scale nonlinear control system, decentralized (not divided) systems with cooperation should be constructed. This paper presents ways to construct decentralized systems for an electric power system. In section 2, swing data of a three‐machine model system are obtained, in section 3, coefficient parameters of the model equation based on one‐machine infinite‐bus system with AVR and GOV are estimated by the least square method. In section 4, the equivalence calculated using estimated values is discussed, and the effect of conditions on fault is considered. Finally, section 5 is devoted to summarizing results of decentralized system identification.
