摘要:
This note shows that the Lyapunov function constructed for the example multimachine power system by Saekiet al. (1985) is in error. The derivative of the Lyapunov function along the trajectories is not negative-semidefinite. This problem raises questions as to whether the hypotheses of Saekiet al.(1985 Theorem 1) can be satisfied in a multimachine power system with transfer conductances.
