Patent ID: 8014905

Claim:
An electricity demand limiting system for limiting the electricity consumption of at least one resistive load device from an electricity delivery system, the demand limiting system comprising: a consumption control circuit positioned between the electricity delivery system and the resistive load device; and a load controller in operative communication with the consumption control circuit to provide a control signal to the consumption control circuit such that the consumption control circuit responsively limits the electricity consumption of the resistive load device, while achieving an established demand associated with the resistive load device, based upon the control signal, wherein the load controller is operable to determine at least one of (1) the thermodynamic gain characteristics of the resistive load device and (2) the historical run and recovery time data of the resistive load device, wherein the load controller generates the control signal to operate the consumption control circuit to achieve a desired thermal recovery or temperature as a function of the at least one of (1) the thermodynamic gain characteristics of the resistive load device and (2) the historical run and recovery time data of the resistive load device, where the load controller infinitely regulates the electricity consumption of the resistive load device as a function of a parameter of the control signal, the demand associated with the at least one resistive load including a set point and a predetermined time and the control signal is generated to limit the consumption of electricity by the resistive load and to meet the demand.
