Abstract :
The paper provides a comparative study of three methods for transient security assessment of power systems: step-by-step simulation, Lyapunov´s direct method and an empirical method based on the kinetic energy of the system. Different ways of formulating the Lyapunov algorithm are shown, and the basic concepts are summarised in a simple form. Particular emphasis is given to the application of the methods to relatively large practical problems with case studies and comparative results provided.
