Patent ID: 8712592

Claim:
A method of controlling a resource demand system, comprising: obtaining weather data from at least one data source that collects weather data at a plurality of areas; calculating a weather value for a target location from the weather data; sensing a weather value for the target location; comparing the calculated weather value with the sensed weather value to validate at least one of the calculated weather value and the sensed weather value; if a difference between the calculated weather value and the sensed value is greater than a sensed margin, then determining whether the calculated weather value or the sensed weather value is accurate, comprising comparing the calculated weather value with collected weather data, wherein the collected weather data is representative of weather of at least one of the plurality of areas; and calculating a control value based on either the calculated weather value or the sensed weather value depending upon whether the calculated weather value or the sensed weather value is determined to be accurate, wherein the calculated weather value is determined to be erroneous if the difference between the calculated weather value and the sensed value is greater than the sensed margin and the difference between the calculated weather value and the collected weather data is outside of a collected weather data margin.
