We observed the resemblance between the frequency response type representation of the hetero-P.R. and that of Duffing's equation (nonlinear ODE). We further noticed that stability of One-Machine-to-Quasi-Infinite-Bus power system approximately corresponds to the \"jump phenomena\" of Duffing's equation. This fact has been confirmed by theory and simulation, and \"Relationship of Marginal Parameters\" is proposed. Extension of this idea to a multi-machine power system is suggested as a future problem.","PeriodicalId":241767,"journal":{"name":"Proceedings.

ICLNN conduct similar functionality as the convcntional clustering algorithm that classifies sensor signal in sclf-organising manner.
