SYSTEM AND METHOD FOR MANAGING LOADS
First Claim
1. A power management system for a facility, comprising:
- a central controller configured to be coupled to a power source and to monitor power drawn by loads in the facility from the power source; and
a plurality of load controllers, each configured to be coupled to an associated load, to control an operational status of the associated load, to be coupled to the central controller via a communications network, and to transmit a power request from the associated load to the central controller via the communications network; and
wherein the central controller comprises a power profile for each one of the associated loads, and is configured to receive a power request from at least one of the plurality of load controllers and conduct an evaluation of the power request based on current power drawn by loads in the facility, power capacity available from the power source, and the power profiles of each one of the associated loads, and based on the evaluation provide a response to the at least one of the plurality of load controllers to control an operational state of a load associated with the at least one of the plurality of load controllers.

12. A power management method for a facility, comprising
receiving an indication of power capacity available from a power source; -
monitoring current power drawn by loads in the facility from the power source; associating, by a central controller, a power profile with each one of the loads; receiving, by the central controller, a power request from a first load controller coupled to a first one of the loads; evaluating the power request based on current power drawn by loads in the facility, power capacity available from the power supply, and the power profiles of each one of the loads; and providing, based on the act of evaluating, a response to the first load controller to control an operational state of the first one of the loads. - View Dependent Claims (13, 14, 15, 16, 17)

18. A non-transitory computer-readable medium encoded with instructions for execution on a central controller within a facility, the instructions when executed, performing a method comprising acts of:
-
receiving an indication of power capacity available from a power source; receiving an indication of current power drawn by loads in the facility from the power source; associating a power profile with each one of the loads; receiving a power request from a first load controller coupled to a first one of the loads; evaluating the power request based on current power drawn by loads in the facility, power capacity available from the power supply, and the power profiles of each one of the loads; and providing, based on the act of evaluating, a response to the first load controller to control an operational state of the first one of the loads. - View Dependent Claims (19, 20)
