This article is a brief overview of some of the research work in the past few years on Transient Stability assessment of Power Systems by the so-calles second method of Lyapunov. The paper concentrates specifically on the structure preserving models, which have been tha basis for further improvements on system stability analysis using Lyapunov Fuctions also know as Transient Energy Fuctions (TEF) to obtain reasonable estimates of the region of attraction for the post-fault stable equilibrium point. The most significant achievements are briefly discussed and a small five-bus Power System is used as an example for the application of these techniques. A critique of this approach and some research ideas are presented.
