This paper investigates the exponential stability problem for a class of multi-area power systems with time delaysunder load frequency controller failures (LFCFs). For describing the phenomenon of LFCFs, the considered multi-areapower system is rewritten as a switched system with multiple time delays. By adopting the switching technique, theexponential stability conditions for multi-area power systems are developed when the controller failure frequency andthe unavailability ratio of the controller are restricted. Finally, one example is given to show the applicability of theproposed method.
