  This papers highlights the benefit of coordinating resources on mulitple
active distribution feeders during severe long duration outages through
multi-microgrid formation. A graph-theory based multi-microgrid formation
algorithm is developed which is agnostic of the underlying energy management
scheme of the microgrids and solved in a rolling horizon fashion. The algorithm
is then enhanced to handle multiple feeders where formation of long laterals
needs to be avoided due to potential voltage control issues in distribution
systems. The algorithm is evaluated on a synthetic two feeder system derived
from interconnecting two IEEE 123 node system. The results indicate increased
service to loads in the system and better utilization of renewable resources.
