Energy management system to reduce the loss of excess energy generation

1. A device for energy management comprising:

a central processing unit (CPU) and memory where the CPU is configured to:

engage an energy load device of highest priority not already engaged via a control signal, wherein the control signal invokes a set point override followed by a set point modification, if an energy supply level (ESL) less an error margin value, is greater than a measured energy consumption level (EDL), and wherein the error margin value is based on a hysteresis effect to the device for energy management; and

disengage an energy load device of lowest priority not already disengaged via a release signal, wherein the release signal invokes a relinquishment of an override followed by a restoration of an original set point, if the energy supply level is less than or equal to the measured energy consumption level.

2. The device of claim 1 wherein the control signal comprises a command to override a set point of a regulated energy load device; and the release signal comprises a command to restore a set point of a regulated energy load device having an overridden set point.

3. The device of claim 1 wherein the control signal comprises a command to shift one or more set points, of a regulated energy load device, from nominal values to preset values stored at the regulated energy load device; and the release signal comprises a command to restore one or more shifted set points of a regulated energy load device to the nominal values.

4. The device of claim 1 wherein the control signal comprises one or more set point updates and a command to replace nominal values of one or more set points of a regulated energy load device with an update value; and the release signal comprises a command to restore one or more updated set point values of a regulated energy load device to the nominal values.

5. The device of claim 1 wherein the control signal comprises one or more set point updates and a command to replace one or more set points of a regulated energy load device with an update value; and the release signal comprises nominal values and a command to replace the one or more updated set point values of a regulated energy load device with the received nominal value.

6. The device of claim 1 wherein the device is further configured to provide excess power to an external grid; and wherein a provisioning of excess power to the external grid is based on a capacity of the external grid to receive the excess power.

7. The device of claim 1 wherein the measured energy consumption level is based on an input energy level of dissipation by one or more active loads.

8. A method for energy management in a system of one or more energy load devices, wherein the system further comprises a system controller, the system controller comprising: a processor and memory, the method comprising:

if the system comprises two or more energy load devices, then establishing an energy load device priority among the two or more energy load devices;

determining, by the system controller, an energy supply level to the system;

determining, by the system controller, a total energy consumption level based on the one or more energy load devices;

determining, by the system controller, an error margin value based on a hysteresis effect to the system of one or more energy load devices for energy management;

if the energy supply level less the error margin value is greater than a measured energy consumption level, then the system controller engaging a load device of highest priority not already engaged via a control signal, wherein the control signal invokes a set point override followed by a set point modification; and

if the energy supply level is less than or equal to the measured energy consumption level, then the system controller disengaging a load device of lowest priority not already disengaged via a release signal, wherein the release signal invokes a relinquishment of an override followed by a restoration of an original set point.

9. The method of claim 8 wherein engaging by the system controller is via a control signal comprising a command to override a set point of a regulated energy load device; and the disengaging by the system controller is via a release signal comprising a command to restore a set point of a regulated energy load device having an overridden set point.

10. The method of claim 8 wherein engaging by the system controller is via a control signal comprising a command to shift one or more set points, of a regulated energy load device, from nominal values to preset values stored at the regulated energy load device; and the disengaging by the system controller is via a release signal comprising a command to restore one or more shifted set points of a regulated energy load device to the nominal values.

11. The method of claim 8 wherein the engaging by the system controller is via a control signal comprising one or more set point updates and a command to replace nominal values of one or more set points of a regulated energy load device with an update value; and the disengaging by the system controller is via a release signal comprising a command to restore one or more updated set point values of a regulated energy load device to the nominal values.

12. The method of claim 8 wherein the engaging by the system controller is via a control signal comprising one or more set point updates and a command to replace one or more set points of a regulated energy load device with an update value; and the disengaging by the system controller is via a release signal comprising nominal values and a command to replace the one or more updated set point values of a regulated energy load device with the received nominal value.

13. The method of claim 8 further comprising:

determining by the system controller whether the system has excess power; and

determining by the system controller a capacity of an external grid to receive excess power generated by the system.

14. The method of claim 13 further comprising delivering by the system controller to an external grid having a determined capacity to receive excess power.

15. The method of claim 8 wherein the measured energy consumption level is based on an input energy level of dissipation by one or more active loads.
