POWER GRID SYSTEMS AND METHODS WITH ZONAL AUTONOMOUS CONTROL

A power grid system provided herein. The power grid system includes an assigned distribution zone of a plurality of distribution zones. The assigned distribution zone is divided into a plurality of sub-zones. Each of the plurality of sub-zones includes a sub-zonal measurement device and a sub-zonal control device. A distribution zonal controller is associated with the assigned distribution zone and IS in communication with the sub-zonal measurement devices and the sub-zonal control devices. The distribution zonal controller is configured to: receive sub-zonal operational data for each of the plurality of sub-zones from the sub-zonal measurement devices; determine a power restoration feasibility index for the assigned distribution zone based on the sub-zonal operational data; determine a restoration control action based on the power restoration feasibility index; and communicate a command to sub-zonal control devices based on the restoration control action.
