Power delivery at both the transmission and distribution levels face several new challenges, including the sheer complexity that results from the introduction of new devices such as smart meters, electric and hybrid vehicles, photovoltaic arrays, and micro wind turbines. These challenges must be met while at the same time preserving the reliability and availability of the existing system. The grid is a ship that must be rebuilt at sea. This report identifies the issues that need to be addressed in achieving the goal of a transmission smart grid. It addresses the communication and computing foundations for an intelligent grid and briefly discusses how to deploy them in transmission applications.
