Linear performance indices to pbkp_redict oscillatory stability problems in power systems

Abstract:

Various indices are proposed and studied to detect and pbkp_redict oscillatory instabilities associated with Hopf bifurcations (HBs) in power systems. A methodology is also presented to produce a linear profile for these indices. They are based on eigenvalue and singular values of the state and extended system matrices. Their application to several test power systems is presented to demonstrate their usefulness, particularly for online applications.
