| Outline of Final Research Achievements |
In this research, new analysis and control design methods for the transient stability of electric power systems consisting of multiple generators are established by using the fundamental nonlinear dynamics of the systems. The following results are obtained. 1) New conditions concerning the synchronization of the generators were presented by using the swing equation of the generators. 2) New Lyapunov functions were designed by using the sum of squares program and estimating more precisely the regions of attraction of the stable equilibrium points of the power systems, which yields a better analysis of the transient stability of the systems. 3) Design methods of stabilization controller of the power systems were proposed by focusing on the representative pole. 4) New analysis methods on the synchronization phenomena of multiple metronomes mounted on the common bases were achieved by using the describing function method, and experimental verifications were carried out.
