Abstract :
A computationally efficient algorithm for transient stability simulation of large scale power system dynamics is described. Certain modifications to the method of H.W. Dommel and N. Sato (see IEEE Trans. PAS, vol.PAS-91, p.1643-50, 1972) with which significant improvement in computational efficiency could be achieved are proposed. Preliminary investigations on a standard test system and on a large practical system indicate that the number of network solutions required for convergence per time step can be reduced at least by half
