Abstract: Microgrids with high penetration of photovoltaic (PV) resources are becoming more common in the energy infrastructure landscape including islanded microgrids occurring in rural areas where establishing new electric services are prohibitively expensive. In the case of islanded microgrids, the lack of cost effective, long duration storage …
The electrical grid exists to supply our electricity demand, ensuring the two are balanced and connecting electrical supply to electrical demand with the transmission and distribution system. In practice, a microgrid works in the exact same way, just for a smaller geographic area, like a couple of buildings or a local community.
The Rhode Island Office of Energy Resources commissioned a report, Resilient Microgrids for Critical Services. In the wake of multi-day power outages due to severe weather events in recent years, OER sought consultant support for design of a program intended to enhance the energy assurance of critical infrastructure through …
