1. A control system for an electric power grid configured to supply electric power from a supply point to a plurality of consumption 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 consumption locations, and wherein each sensor is configured to sense a component of the supplied electric power received at the respective distribution location and to generate measurement data based on the sensed component of the power;
a controller configured to receive measurement data from the plurality of sensors, and to operate the electric power grid in a modification-on state or in a modification-off state;
wherein the controller generates an energy delivery parameter based on the measurement data;
a component adjusting device configured to adjust a component of the electric power grid in response to the energy delivery parameter;
wherein the controller is configured to determine, using an energy validation process, the change in energy characteristics between the modification-on state and the modification-off state, using a paired comparison, wherein the paired comparison includes a pairing process and the pairing process includes applying at least one filter selected from the group consisting of;
a temperature filter configured to not pair records that are not within a predetermined temperature difference,a prior time filter configured to not pair records that are not within a predetermined average temperature difference for a predetermined prior time period immediately preceding the time when the records were taken,a relative humidity filter configured to not pair records that are not within a predetermined humidity difference,an interval index filter configured to order sub-interval periods by a loading impact of each sub-interval period and to not pair records that are not within a predetermined index offset value,MW filter configured to not pair records that not within a predetermined MW difference,a voltage filter configured to not pair records that not within a predetermined voltage difference,a linear value correlation filter configured to not pair records that not within a predetermined linear correlation factor, andan outlier filter configured to exclude paired records greater than a predetermined Median Absolute Deviation (MAD).
