Abstract

In one embodiment, a grid application function is hosted at a primary grid device in a utility grid, which may determine whether or not to distribute at least a portion of the grid application function to one or more distributed secondary grid devices in the utility grid. In general, the one or more distributed secondary grid devices will be associated with a subset of the utility grid that is associated with the primary grid device (e.g., a sub-grid). Once a determination has been made, the primary grid device may dynamically distribute the grid application function, or a portion thereof, to the distributed secondary devices according to the determination. In addition, in another embodiment, the grid application function may also be withdrawn, such as from a particular secondary grid device or else from the primary grid device to an originating grid device.

Claims

1. A method, comprising:

hosting a grid application function at a primary grid device in a utility grid;

determining whether to distribute at least a portion of the grid application function to one or more distributed secondary grid devices in the utility grid, the one or more distributed secondary grid devices associated with a subset of the utility grid associated with the primary grid device; and

dynamically distributing the grid application function according to the determining.

2. The method as in claim 1, wherein the grid application function at the primary device is distributed from an originating grid device associated with a superset of the utility grid associated with the primary grid device.

3. The method as in claim 2, further comprising:

determining that the grid application function is no longer to be used at the primary grid device; and

, in response,

withdrawing the grid application function from the primary grid device back to the originating grid device.

4. The method as in claim 1, wherein determining is based on analysis of utility grid parameters selected from a group consisting of:

a processing capability of the originating, primary, or secondary grid device;

a processing load on the originating, primary, or secondary grid device;

a latency requirement for the grid application function;

a state of the utility grid;

a state of the subset of the utility grid;

a size of the utility grid associated with the primary device;

a size of the utility grid associated with the one or more distributed secondary devices; and

any combination thereof.

5. The method as in claim 1, wherein dynamically distributing further comprises:

determining that the grid application function is no longer to be used at the secondary grid device; and

, in response,

withdrawing the grid application function from the secondary grid device back to the primary grid device.

6. The method as in claim 1, wherein dynamically distributing further comprises:

distributing responsibility for the grid application function.

7. The method as in claim 1, wherein dynamically distributing further comprises:

distributing an application code for the grid application function.

8. The method as in claim 1, wherein determining comprises:

receiving user input directing the determining.

9. The method as in claim 1, wherein the at least a portion of the grid application function comprises all functions related to the subset of a corresponding secondary grid device or a portion of all the functions.

10. The method as in claim 1, wherein the at least a portion of the grid application function corresponds to the utility grid associated with the primary grid device.

11. The method as in claim 1, wherein determining further comprises:

making an individual determination as to the processing capacity of each of the one or more distributed secondary grid devices in the utility grid; and

dynamically distributing the grid application function according to the individual determination.

12. The method as in claim 1, wherein the originating, primary, and/or secondary grid devices comprise at least one processing element selected from the group consisting of:

enterprise servers;

cloud virtualized servers;

cloud servers;

operations/control center virtualized servers;

substation computing platforms;

field area routers;

embedded grid devices;

balance/interchange servers;

premises devices; and

grid-attached embedded devices/systems.

13. An apparatus, comprising:

one or more network interfaces to communicate with a utility grid or sub-grid computer network;

a processor coupled to the network interfaces and adapted to execute one or more processes; and

a memory configured to store a process executable by the processor, the process when executed operable to;

host a grid application function as a primary grid device in the utility grid;

determine whether to distribute at least a portion of the grid application function to one or more distributed secondary grid devices in the utility grid, the one or more distributed secondary grid devices associated with a subset of the utility grid associated with the primary grid device; and

dynamically distribute the grid application function according to the determination.

14. The apparatus as in claim 13, wherein the grid application function at the primary device is distributed from an originating grid device associated with a superset of the utility grid associated with the primary grid device.

15. The apparatus as in claim 14, wherein the process when executed is further operable to:

determine that the grid application function is no longer to be used at the primary grid device; and

, in response,

withdraw the grid application function from the primary grid device back to the originating grid device.

16. The apparatus as in claim 13, wherein determine is based on analysis of utility grid parameters selected from the group consisting of a processing capability of the originating, primary, or secondary grid device;

a processing load on the originating, primary, or secondary grid device, a latency requirement for the grid application function, a state of the utility grid, a state of the subset of the utility grid, a size of the utility grid associated with the primary device, a size of the utility grid associated with the one or more distributed secondary devices, and any combination thereof.

17. The apparatus as in claim 13, wherein the process when executed is further operable to:

determine that the grid application function is no longer to be used at the secondary grid device; and

, in response,

withdraw the grid application function from the secondary grid device back to the primary grid device.

18. The apparatus as in claim 13, wherein the process, when executed to dynamically distribute, is further operable to:

distribute at least one of either responsibility or application code for the grid application function.

19. A tangible, non-transitory, computer-readable media having software encoded thereon, the software, when executed by a processor at a primary grid device in a utility grid, operable to:

host a grid application function;

determine whether to distribute at least a portion of the grid application function to one or more distributed secondary grid devices in the utility grid, the one or more distributed secondary grid devices associated with a subset of the utility grid associated with the primary grid device; and

dynamically distribute the grid application function according to the determining.

20. The computer-readable media of claim 19, wherein the software when executed is further operable to:

determine that the grid application function is no longer to be used at the secondary grid device; and

, in response,

withdraw the grid application function from the secondary grid device back to the primary grid device.
