Abstract

Unique systems, methods, techniques and apparatuses of a power grid control system. One exemplary embodiment is a microgrid comprising a plurality of switching devices, a plurality of distribution line segments, a plurality of measuring devices, each measuring device corresponding to one of the plurality of switching devices, and a network controller. The network controller is configured to: receive measurements from the plurality of measurement devices, determine a fault is occurring within the microgrid using the measurements, assign a topology classification to each of the plurality of distribution line segments, assign a proximity classification to each of the plurality of distribution line segments, determine fault location using the topology classification and the proximity classification, and isolate the fault by transmitting open commands to the two switching devices of the plurality of switching devices closest to the fault.
