Abstract

An approach to provide power from power supply devices to power consuming devices using a centralized system. The approach includes a method for configuring micro-grids that comprises the steps of receiving information of a power consuming device and criticality of the power consuming device from a universal appliance service (UAS) system. The method further includes receiving power supply information of one or more power supply devices associated with an electric grid from the UAS system. The method further includes receiving a power request from the power consuming device. The method further includes determining, by a computing device, power requirements for the power consuming device based on the information, the criticality of the power consuming device, and the power supply information.

Claims

1. A method for configuring micro-grids comprising the steps of:

receiving information of a power consuming device and criticality of the power consuming device from a universal appliance service (UAS) system;

receiving power supply information of one or more power supply devices associated with an electric grid from the UAS system;

receiving a power request from the power consuming device; and

determining, by a computing device, power requirements for the power consuming device based on the information, the criticality of the power consuming device, and the power supply information.

2. The method of claim 1, wherein the determining includes determining that the power consuming device receives the power at a delayed start time.

3. The method of claim 1, wherein the UAS system determines the criticality of the power consuming device based on a particular event.

4. The method of claim 1, wherein the UAS system determines the criticality of the power consuming device based on a device type of the power consuming device.

5. The method of claim 1, wherein the computing device receives the criticality of the power consuming device directly from the UAS system via an application programming interface (API).

6. The method of claim 1, wherein the criticality of the power consuming device is changed from a non-critical power consuming device to a critical power consuming device based on a particular event or period of time.

7. The method of claim 1, wherein the criticality of the power consuming device is provided directly to an energy management (EM) system from the UAS system.

8. The method of claim 7, wherein the criticality of the power consuming device is received via a presence server.

9. The method of claim 1, wherein the information is sent from an energy management (EM) system to the UAS system.

10. The method of claim 9, wherein the information includes identifier information for the power consuming device and location information of the power consuming device.

11. The method of claim 1, wherein the determining the power consuming device receives the power includes:

determining an amount of power being requested by the power consuming device;

determining an amount of generated power and an amount of reserve power;

determining that at least one of the amount of generated power and the amount of reserve power is not sufficient to provide the power being requested to the power consuming device while maintaining integrity of the electric grid; and

delaying the power consuming device'"'"'s operation.

12. The method of claim 11, wherein the delaying the power consuming device'"'"'s operation is stopped when the amount of generated power and the amount of reserve power is sufficient to provide the power being requested to the power consuming device.

13. The method of claim 1, further comprising the steps of:

determining an amount of power being requested by the power consuming device;

determining an amount of generated power and an amount of reserve power;

determining that the at least one of the amount of generated power and the amount of reserve power is below a level of power to operate the power consuming device;

shutting down operations of the power consuming device; and

sending a message that the power is not available for the power consuming device.

14. The method of claim 1, wherein:

the steps of claim 1 are provided by a service provider on at least one of a subscription, advertising, and fee basis; and

the service provider at least one of creates, deploys, and maintains a computer infrastructure that executes the steps of claim 1.

program instructions to send the criticality levels to a micro-grid manager, wherein the micro-grid manager determines that power is available from the power supply devices to operate the power consuming devices based on the criticality levels;

wherein each of the program instructions are stored on the computer readable storage media for execution by the CPU via the computer readable memory.

16. The system of claim 15, further comprising program instructions to receive the information from device manufacturers which are the validated third party sources.

17. The system of claim 16, wherein the information from the device manufacturers includes electrical characteristic information and device identifier information.

18. The system of claim 15, wherein the criticality level of at least one of the power consuming devices changes based on an occurrence of an event.

19. A computer program product for determining criticality, the computer program product comprising a computer usable storage medium having program code embodied in the storage medium, the program code readable/executable by a computing device operable to:

receive real time information for a power consuming device from a UAS system, wherein the real time information includes the criticality of the power consuming device;
