Energy management system and method
First Claim
1. An energy management system for at least one managed device disposed to receive energy via a meter connected to an energy supply including at least one of an secondary external energy source and an internal energy source, the internal energy source configured to provide primary power for the at least one managed device, the system comprising:
- a system controller comprising a computer processor configured for communication with the at least one managed device, the meter, and a computer readable storage medium containing computer executable instructions that when executed by the computer processor performs a method comprising;
obtaining an energy consumption rate of the at least one managed device from the meter;
determining whether the energy consumption rate exceeds energy available from the internal energy source configured to provide primary power for the at least one managed device;
obtaining demand information from a demand information source, the demand information comprising information about a demand state of the external energy source;
determining from the demand information whether the demand state of the external energy source is a peak demand state;
determining a priority of the at least one managed device;
determining an energy need of the at least one managed device; and
instructing the at least one managed device to employ an operational mode based on the priority, the energy need, the demand state and whether the energy consumption rate of the at least one managed device exceeds energy available from at least one of the external energy source and internal energy source.

Abstract
An energy management system manages energy consumption of managed device(s) disposed to receive energy via a meter connected to an energy supply, the energy supply. A system controller has a computer processor that instructs the managed device(s) to employ an operational mode based on the priority, the energy need, the demand state, and whether the energy consumption rate of the managed device(s) exceeds energy available from at least one of the external energy source and internal energy source.

21. A facility energy management system for a facility connected to and selectively drawing energy from an external energy supply, the system comprising:
-
a computer readable storage medium including computer executable code in a format readable and executable by a computer processor; a system controller including a computer processor and connected to the computer readable storage medium, the system controller configured to load and execute the computer executable code to; receive a facility demand limit; determine a demand state that is one of at least a peak demand state and an off-peak demand state; allocate a facility energy demand of a facility based on a priority of an energy consuming device in the facility and on an energy need of the energy consuming device, the energy need being determined by a minimum energy requirement of the energy consuming device for proper operation; responsive to determining that a local energy storage unit is present and is depleted, initiate charging the local energy storage unit during an off-peak demand state; responsive to determining that a local energy storage unit is present and that an energy demand of the facility exceeds the demand limit, draw energy from the local energy storage unit; responsive to determining that a local energy generation device is present, initiate drawing energy from the local energy generation device when an energy demand of the facility exceeds the demand limit; responsive to a high priority of the energy consuming device, instruct the energy consuming device to employ a normal operational mode; responsive to a low priority of the energy consuming device, instruct the energy consuming device to employ a reduced operational mode; responsive to an energy need of the energy consuming device exceeding an amount of energy supplied in a reduced operational mode, override an instruction to employ the reduced operational mode; and responsive to a customer command, override an instruction to employ the reduced operational mode. - View Dependent Claims (22)
