This set of slides was presented at the CNLS Smart Grid Seminar Series at Los Alamos National Lab on Aug 25, 2009. Federal programs are subsidizing deployments of smart grid elements. But for these initial deployments to grow, the smart grid needs to become self sustaining. This will require modifications in system operations that create a level field for both reliable and interruptible power. One such modification is proposed, founded on the concept of risk-limiting dispatch, and realized in a way that permits incremental deployment. The current practice of worst-case dispatch assumes reliable power sources and limited information. Risk-limiting dispatch relies on information—from sensors, generators and customers—to coordinate interruptible power sources and demand response.
