1. A control system for an electric power transmission and distribution grid configured to supply electric power from a supply point to a plurality of user locations, the system comprising:

  • a plurality of sensors, wherein each sensor is located at a respective one of a plurality of distribution locations on the distribution grid at or between the supply point and at least one of the plurality of user locations, and wherein each sensor is configured to sense a component of the supplied electric power at the respective distribution location and to generate measurement data based on the sensed component of the power;

    a controller configured to generate an energy delivery parameter based on a comparison of the measurement data received from the sensors to a controller target band; and

    ,a component adjusting device configured to adjust a component of the electric power transmission and distribution grid in response to the energy delivery parameter;

    wherein the controller target band has upper and lower limits, the upper and lower limits defining a range of acceptable values for the component of electric power at the distribution locations,wherein the controller is configured to derive a linear model for at least one power loss from an upstream location to a downstream location and optimize through linear optimization a control point for the component adjusting device.
