1. A power device controller for controlling a power distribution system having at least one feeder, at least one electromechanical device and at least one distributed energy resource without using a power flow model, the controller comprising:

  • a communication transceiver structured to receive electrical measurements from a plurality of electronic power meters, the transceiver additionally structured to transmit perturbation signals to the at least one electromechanical device, and the transceiver additionally structured to transmit control signals to the at least one electromechanical device and at least one distributed energy resource;

    a memory device structured to store electrical measurements received by the communication transceiver; and

    a processing unit structured to receive electrical measurements from the communication transceiver, transmit perturbation signals and control signals to the communication transceiver, receive data stored on the memory device, transmit data to the memory device to be stored, and programmed to;

    receive historical measurements generated by the plurality of electronic power meters and electromechanical devices,determine the sensitivities of system voltages over the change in aggregate real power consumption, aggregate reactive power consumption, aggregate distributed energy resource real power generation, and aggregate distributed energy resource reactive power generation, switched capacitor bank reactive power generation and voltage regulator tap position,identify a predictive model based on the determined voltage sensitivities, andtransmit at least one command signal to the communication transceiver, each command signal being structured to modify power line characteristics by controlling a setting of one of the electromechanical devices or one setting of the distributed energy resources.
