| Abstract | ||
| This paper presents a brief description of Lyapunov's direct method, and demonstrates its efficiency with respect to previous indirect step by step method, in order to compute the stbility of electromechaincal power system. The practical advantages of this direct method of analysis are: (i) Rapid solution. (ii) Ability to compute the degree of stability. The limitations that Lyapunov's direct method suffers from: a) Severe modeling limitations. b) If the system is unstable, the analysis does not indicate how it separates and whether the separated parts survive of collapse. The basic concepts and the mathematical formulation of the method are summarized. Practical test system are used to demonstrate the superior efficiency of the method relative to step by step method. | ||
