Transient stability analysis of power system based on complex network theory

摘要

This paper investigates the transient stability of power systems under the framework of complex network theory. The studied power system is assumed to be singularly perturbed so that the corresponding reduced-order system is a Kuramoto-oscillator system in complex network theory. A condition is presented to guarantee the bounded synchronization of reduced system with an arbitrary topology so that the original system is transiently stable. The effectiveness of this condition is verified by simulation results on IEEE 57-bus and 118-bus power systems.
