Abstract

In this paper a new notion of power system stability, is introduced, namely structural stability, and its significance in the context of load modeling is examined. It is shown that beyond certain values of load indices in the case of static models and beyond certain value of the dynamic component in the load such as induction motors, the system may become structurally unstable. The immediate application of these results is in the voltage stability problems.
