The goal of this FOA is to conceive and develop scenarios, approaches, methodologies, tools, techniques and systems that maximize the bi-directional exchange of grid services while optimizing connectivity and information exchange at the grid edge to IoT interface that leads to enhanced system resilience and reliability. These advancements must be applicable to the scenario of maintaining energy surety to defense installations, where coordination between defense facilities, the utility, and surrounding DER can extend the functioning of those facilities through normal and abnormal events.
