Energy conservation using active demand stabilization

A system with electric power demand stabilization comprising:

• a plurality of controllable devices within an industrial cold storage facility, wherein the plurality of controllable devices comprises two or more different controllable devices selected from the group consisting of a motor, fan, turbine, valve, refrigerant vessel, evaporator, condenser, compressor, underfloor heating element, defrost equipment, and centrifuge, wherein each controllable device of the plurality of controllable devices is disposed within the industrial cold storage facility;
• a plurality of environmental sensors configured to measure aspects of the industrial cold storage facility environment;
• and
• a facility coordinator in communication with the plurality of controllable devices and the plurality of environmental sensors, the facility coordinator is configured to:
• measure a power draw of the plurality of controllable devices over a period of time using one or more of the plurality of environmental sensors;
• determine a rolling average power draw for the plurality of controllable devices over the period of time;
• measure an instantaneous power draw of the plurality of controllable devices using one or more of the plurality of environmental sensors, wherein the instantaneous power draw of the plurality of controllable devices is estimated based at least in part on the on and off states of the plurality of controllable devices;
• calculate a power budget comprising the difference between the instantaneous power draw and the rolling average power draw;
• in the event the power budget is positive, increase power to at least a first subset of the plurality of controllable devices, wherein the first subset of the plurality of controllable devices includes fewer than the plurality of controllable devices and wherein the first subset of the plurality of controllable devices comprises at least one of a motor, fan, turbine, valve, refrigerant vessel, evaporator, condenser, compressor, underfloor heating element, defrost equipment, and centrifuge;
• and
• in the event the power budget is negative, decrease power to at least a second subset of the plurality of controllable devices, wherein the second subset of the plurality of controllable devices includes fewer than the plurality of controllable devices and wherein the second subset of the plurality of controllable devices comprises at least one of a motor, fan, turbine, valve, refrigerant vessel, evaporator, condenser, compressor, underfloor heating element, defrost equipment, and centrifuge.
