Abstract
In this paper the effect of small random perturbations on dynamic system modeling and its application to the reliability evaluation of a multi-machine power system is studied. Small perturbations in the operational characteristic of transmission lines and system loads have been regarded as inputs to the system model and a reliability measure has been proposed based on the mean first passage time of the system from its stability region. The effectiveness of the proposed reliability index in considering system dynamics and its sensitivity to the variation of different system parameters have been studied. Also, several design criteria have been examined to determine the effect of system configuration on power system dynamics and its reliability evaluation. In addition, specific policies have been introduced to determine the robustness of different planning alternatives in handling imminent outages. This technique does not set any restrictions as to how the buses are interconnected and it can be implemented on a large scale power system.
