In view of such problems as phase divergence, voltage collapse, and even power outages found in chaotic power systems, a finite time stability control strategy, which is based on hybrid pulse control, has thus been proposed for chaotic dual machine interconnected power systems. In a chaotic dual machine interconnected power system, a finite time stable hybrid pulse control design is proposed, enabling it to enter a stable operating state within a finite time. Finally, the effectiveness and validity of the proposed method and control strategy are to be verified through simulation experiments.
