DHS To Review Report On US Power Grid Vulnerability

CWmike writes "The US Department of Homeland Security is looking at a report by a research scientist in China that shows how a well-placed attack against a small power subnetwork could trigger a cascading failure of the entire West Coast power grid. Jian-Wei Wang, a network analyst at China's Dalian University of Technology, used publicly available information to model how the West Coast grid and its component subnetworks are connected. Wang and another colleague then investigated how a major outage in one subnetwork would affect adjacent subnetworks. New Scientist magazine reported on this a week or so ago, and the paper has been available since the spring."

Fragile Grid

[Old VMS Junkie]

The electric grid has already suffered multiple cascading failures from simple events that led to widespread outage. Look into the West Coast outages of 1996 and 1998 as well as the failure in the Northeast in 2003. There's a lot of interesting science going on around networks, graph theory, complexity and all. There's a really good book on teh subject, "Six Degrees" by Watts.
