The electric grid in America is aging and losing many of its positive attributes. We need to update the grid to facilitate the transmission and distribution of renewable energy - energy generated by solar, wind and other renewable sources.
A variety of changes in the electrical grid are described in this article. These changes include: microgrids, demand response, advanced metering, grid scale energy storage devices, and updated grid hardware. These changes help to define the future of the grid.
This article provides an extensive array of challenges to the current electric grid and proposes a wide and convincing argument for broad and technically refined changes in the grid. It also describes what any new grid needs to be like and what it should accomplish.
