A far-reaching vision for the future of the electric grid is emerging at the U.S. Department of Energy’s (DOE’s) National Renewable Energy Laboratory. In the past few years, this vision has grown from a theory on whiteboards to real-power experiments on lab hardware.   It’s called “Autonomous Energy Grids” (AEG), an effort to ensure the grid of the future can manage a growing base of intelligent energy devices, variable renewable energy, and advanced ...
