Abstract

An approach to provide power from power supply devices to power consuming devices based on characteristics of the power consuming devices and/or the power supply devices. The approach includes a method that includes receiving information of a power consuming device from an energy management system that determines criticality of the power consuming device. The method further includes receiving power supply information of one or more power supply devices associated with an electric grid. The method further includes receiving a power request from the power consuming device. The method further includes determining that the power consuming device receives power from the power supply device, based on the information and the power supply information.

Claims

1. A method for configuring micro-grids comprising:

receiving information of a power consuming device from an energy management (EM) system, wherein the EM system determines criticality of the power consuming device at a device level;

receiving power supply information of one or more power supply devices associated with an electric grid;

receiving a power request from the power consuming device; and

determining, by a computing device, that the power consuming device receives power from the power supply device, based on the information and the power supply information.

2. The method of claim 1, wherein the information of the power consuming device includes identification that the power consuming device is a critical power consuming device or a non-critical power consuming device.

3. The method of claim 2, wherein the power consuming device has priority when the power consuming device is a critical power consuming device.

4. The method of claim 1, wherein the power supply information includes whether the power supply device is operating and generating power or is in standby mode.

5. The method of claim 1, wherein the receiving the information and the power supply information are sent using one of:

Simple Internet Protocol (SIP) communication messages and Message Queue Telemetry Transport (MQTT) messages.

6. The method of claim 1, wherein the receiving the power supply information includes receiving the power supply information from another energy management (EM) system of the power supply device.

7. The method of claim 6, wherein:

the power supply information is received as a power supply profile and the information is received as a load profile;

the power supply profile is associated with one or more of the power supply devices; and

the load profile is associated with the power consuming device and additional power consuming devices.

8. The method of claim 7, wherein the another EM system configures the power supply profile.

9. The method of claim 1, wherein the determining includes determining that a power flow and power quality of the electric grid is maintained when the power consuming device receives the power.

10. 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 available; and

determining that at least one of the amount of generated power and the amount of reserve power is sufficient to provide the requested power by the power consuming device while maintaining integrity of the electric grid.

11. The method of claim 10, wherein when there is not enough power for a non-critical power consuming device, placing the non-critical power consuming device into a queue for a delayed start until the power is available.

12. The method of claim 11, further comprising sending a message to the computing device that the power is not available for the non-critical power consuming device.

13. The method of claim 1, wherein a service provider at least one of creates, maintains, deploys and supports the computer infrastructure.

14. The method of claim 1, wherein steps of claim 1 are provided by a service provider on a subscription, advertising, and/or fee basis.

15. A system comprising:

a CPU, a computer readable memory and a computer readable storage media;

program instructions to receive information regarding power consuming devices;

program instructions to receive criticality levels from an EM system for each of the power consuming devices, wherein the EM system determines the criticality levels;

program instructions to receive power supply information regarding power supply devices;

program instructions to determine that power is available from the power supply devices to operate the power consuming devices; and

program instructions to place a request for power of a non-critical power consuming device into a queue for a delayed operating time when there is not enough power to operate both a critical power consuming device and the non-critical power consuming device;

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 allocate the power to each of the power consuming devices based on the power from the power supply devices and the priority of each of the power consuming devices.

17. The system of claim 16, wherein the power supply information includes a maximum amount of power generated by the power supply devices, voltage values for the power supply devices, age of the power supply devices, and a location of the power supply devices.

18. The system of claim 16, wherein the information includes power demand information, location of the power consuming devices, and a quantity of the power consuming devices.

19. The system of claim 16, wherein the EM system can change the criticality level of one or more of the power consuming devices.

20. A computer program product comprising a computer usage storage device having readable computer code embodied in the storage device, the computer program product includes at least one component to:

receive real time information for a power consuming device from an EM system, wherein the EM system determines a criticality level of the power consuming device;

receive real time power supply information from a power supply device;

determine a power flow for a micro-grid based on the information and the power supply information;

determine reliability of the micro-grid based on the power flow;

determine real time electrical status of the micro-grid based on the real time information and the real time power supply information;

receive an enablement request from the power consuming device, wherein the enablement request is a request for power;

determine whether there is available power for the power consuming device, based on the real time electrical status of the micro-grid;

determine whether the power consuming device has priority for the power over other power consuming devices; and

send the power to the power consuming device based on the priority of the power consuming device and the real time electrical status of the micro-grid.
