The analysis of severe blackouts has become an essential part of transmission grid planning and operation. This may include evaluation of rare-event probabilities, which can be difficult to estimate. While simulation offers flexibility to model large complex systems, efficiency remains a big concern when estimating very small probabilities. This paper presents an effective simulation technique to...
Severe blackouts due to cascading failures in electric grid are rare but catastrophic. The analysis of such blackouts may include evaluation of rare-event probabilities which is difficult to estimate. In this paper, we present an effective rare-event simulation technique to estimate the rare-event probability. We apply our technique to an IEEE-bus electric network and show that our technique can dramatically...
