This set of slides was presented at the CNLS Smart Grid Seminar Series at Los Alamos National Lab on March 9, 2009. Because of the number of components in a power grid it is impossible to plan for and mitigate all sets of failures. Maintaining a high level of reliability in the midst of this risk is challenging. As market forces, variable sources (eg. wind and solar power) and new loads (eg. electric cars) increase stress on power grids, the challenge of managing reliability and costs will certainly increase. Therefore we need strategies that enable the most important services that depend on electricity infrastructure to continue in the midst of risks. This talk will focus on two strategies for enabling the most important services that depend on electricity continue in the midst of significant systemic vulnerability.
