A control system for controlling a power distribution network including a set of devices for providing power commands the devices to reach a consensus on an average of uniquely weighted states of the devices based on iterative exchange of a uniquely weighted state of each device with its neighboring devices. The system determines the values of states of each of the devices corresponding to the received average of uniquely weighted states, determines a new value of the state of at least on device allowing to reroute distribution of the power, and commands to the device to change the state to the new value.

Post-disaster topology detection and energy flow recovery in power distribution network

Systems and methods for configuring micro-grids to restore some power in a power distribution grid (PDG) in response to a power disruption over the PDG. A computing system configured to receive current condition information from devices in the PDG. Form a minimum spanning forest (MSF) to identify a set of micro-grids, each spanning tree in a forest is a self-sustained islanded micro-grid network. Assign a ranking to each inter-bus link within each micro-grid according to constraints, to identify some inter-bus links above a high-ranking threshold to be switched off during a restoration period. Identify switches that restore power to some critical loads of a subset of critical loads with different forest configurations, based on buses that are switched on, to determine a subset of micro-grids less susceptible for link failures during the restoration period. Upon receiving a power disruption, activate the switches to restore some power to the PDG.
