Microgrid Demonstration at the Grid Edge Theater

This year’s live microgrid demonstration will feature a fully operating “hybrid” bi-directional residential microgrid, complete with appliances, HVAC, lighting, EV charging and various plug load distributions including line AC and DC, USB-C, PoE and FMP. Power resources for the microgrid will be a combination of solar, battery and utility energy. The microgrid will power both AC and DC devices and appliances in a simulated residential setting. It will also be interconnected in a simulated multi-tiered grid-of-grids network of other microgrids and the macrogrid.

The demonstration is a multi-vendor system engineered by Direct Energy Partners and includes electrical devices from Emera Technologies Block Energy, CE+T America, LG Appliances and Solar Panels, Trane HVAC, Cisco Systems PoE & FMP, Enteligent EV Charging, PomCube iCan Energy Storage, Nextek Power Systems, ATX LED, Eco-Fasten Solar Mounting, Alencon Optimizers, and many more.  Install of the on-site microgrid will be overseen by Rectify Solar.
