Abstract:
1. A voltage control and energy conservation system for an electric power transmission and distribution grid configured to supply electric power to a plurality of user locations, the system comprising: a substation including a supply point configured to supply electrical power to a plurality of user locations; 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 voltage of the supplied electric power at the respective distribution location and to generate measurement data based on the sensed voltage; a voltage controller configured to receive measurement data from each sensor of a subset of the plurality of sensors, wherein the subset includes more than one and substantially fewer than all of the plurality of sensors, and to generate an energy delivery parameter based on a comparison of the measurement data received from the subset to a controller target voltage band; a voltage adjusting device configured to adjust a voltage of the electric power supplied at the supply point based on the energy delivery parameter; wherein at least one other sensor of the plurality of sensors that is not included in the subset is further configured to send a respective reporting signal to the voltage controller when the voltage sensed by the sensor is determined to be outside of a respective sensor target voltage band; and wherein the voltage controller is configured to, in response to receiving the respective reporting signal, de-select a sensor from the subset and add to the subset the sensor that sent the respective reporting signal.
