Increasing complexity of power grids, growing demand, and requirement for greater grid reliability, security and efficiency as well as environmental and energy sustainability concerns continue to highlight the need for a quantum leap in harnessing communication and information technologies. This leap toward a "smarter" grid is now widely referred to as "smart grid". A framework for cohesive integration of these technologies facilitates convergence of acutely needed standards and protocols, and

We observe that an ideal mix of these resources leads to a flatter net demand that eventually accentuates reliability issues further. We then present a gridwide IT architectural framework to meet the reliability challenges. This architecture supports a multitude of geographically and temporally coordinated hierarchical monitoring and control actions over time scales from milliseconds and up.
