Microgrids are getting a lot of attention, not just to support national security, but also to provide more resilient power supply at other types of facilities, and to allow for increased penetration of renewables. Agricultural complexes, academic campuses, health care centers, military bases, and even corporate grounds are exploring microgrid options to secure continuous reliability and quality of power supply. This has spurred creation of new technologies and control mechanisms that allow these systems to operate in a grid-connected mode and also independently for extended periods of time. They also support the modernization of older infrastructures and the containment of costs.
