The EMerge Alliance will make a presentation about the on-site live microgrid that powers the "Grid Edge" show floor. Included will be explanation of its operation, nanogrid and microgrid components, and digital-twin live dashboard. This "must-see" first ever multi-tier microgrid demonstration, features semi-autonomous distributed intelligent control, and is exclusive to RE+ show attendees. It highlights the virtues of an inevitable transformation of our existing grid to a highly resilient, adaptive and environmentally improved "Grid-of-Grids" architecture.
