Abstract
After nearly four decades of research in power system stability via Lyapunov or energy functions, the method is now on the verge of being implemented for assessment of Online dynamic security. The main bottleneck has been in the proper characterization of the stability boundary and defining the fault-dependent region of attraction locally around the controlling unstable equilibrium points. Now there is a better understanding of this issue and, hence, a number of algorithms have been proposed. Improved generating unit models and transmission network models are now being included in the technique. In this paper, an overview is presented of the theory, practical implementation, and future research issues in this area.
