Abstract

The authors propose a method for the determination of power system transient stability that is based on the global kinetic energy of the power system. The system global energy function is divided into within-group and between-group energies. It is concluded that the within-group kinetic energy at the critical boundary is the amount of energy which need to be corrected for at the clearing time. The region of stability determined by the within-group kinetic energy is compared with that obtained with a UEP (unstable equilibrium point) method. Superior accuracy of the proposed method over the UEP method is demonstrated on a 17-generator, 163-bus test system.<>
