摘要: In this paper we consider the stability analysis of power systems by decomposition. Our approach employs time scale property and its use in decomposition large system into slowly coherent areas. For a composite Lure form, show that slow coherency transformation results fast subsystems which are also form. A weighted sum scalar Lyapunov function is formed from subsystems, properties analysed. numerical example presented to illustrate method.
