Abstract: Unique systems, methods, techniques and apparatuses of a power grid control system. One exemplary embodiment is a nested microgrid system comprising a first microgrid including a network controller, a second microgrid, a third microgrid, a first restoration path selectively coupled between the second portion of the first microgrid and the second microgrid, and a second restoration path selectively coupled between the second portion of the first microgrid and the third microgrid. The network controller is configured isolate the first portion of the first microgrid from the second portion of the first microgrid, calculate weighting factors for the first and second restoration paths, select the first restoration path using the first weighting factor and the second weighting factor, and couple the second portion of the first microgrid to the second microgrid using the first restoration path.
