Abstract

Federal programs are subsidizing deployments of smart grid elements to promote renewable energy. 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 renewable power. Two such modifications are 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 renewable power sources and demand response.
