A novel uncertain power flow analysis method is proposed in this letter. It utilizes evidence theory to fuse probabilistic, possibilistic, and interval uncertainties. Besides, the extended affine arithmetic is applied to handle variable dependencies existed in power flow. The final analysis results are represented as probability boxes (p-boxes). The comparisons with Monte Carlo simulation are given...
It is well known that cascading failure is one of the key factors which lead to blackout events around the world. How to simulate cascading failure reasonably is one of the important issues to be solved by electrical engineers. An ad-hoc cascading failure model based on probabilistic line outage and failure correlation is proposed in this paper. The proposed model involves AC power flow computation...
