Extreme ice disasters may lead to a rapid degradation of power system performance. By using a fault probability model of transmission lines with respect to ice-wind loads, the impacts of ice disasters on power systems can be regarded as transmission line outages. To quantify these consequences, a quantitative resilience index is developed in this paper. Finally, the proposed index is testified on the IEEE RTS-79 test system. Results indicate that different enhancement measures can be evaluated based on the obtained resilience indices.
