When analyzing dynamical stability in power systems, there exist various errors. First, there are analyzing errors which occur in linearlizing non-linear systems on a particular operating condition. Secondly, there are adjusting errors of the parameter values which are the time constants and the gains of the control systems. However, the conventional representative techniques, such as the eigen value method, the Routh-Hurwitz method and the Nyquist method, cannot deal with these kinds of errors. Using these representative methods, if the parameters vary, we have to recalculate the whole system stability. In order to solve this kind of problem, this paper proposes a use of the Kharitonov theorem which is one of the robust control theories.
