  • Patent number: 9454137
    Abstract: A microgrid system may control power distribution among a plurality of interconnected microgrids operated under droop mode. The microgrids may operate both autonomously and as part of the system. Stable power distribution between the microgrids may be performed by monitoring operation of the microgrids and electrically disconnecting the microgrids from one another when a power outage or performance outside of a tolerance is detected. Network lines between the microgrids may remain in communication while the microgrids are disconnected from one another. The microgrids may operate autonomously under a preset operating droop frequency until power stability is detected at a boundary between adjacent microgrids. The microgrids may communicate with one another adjusting operating droop until synchronization among microgrids is achieved and the microgrids can be reconnected into the microgrid system.
