Abstract

In one embodiment, a grid service controller receives advertisements from one or more grid service devices that indicate one or more grid control operations for which a corresponding grid service device is capable, and also maintains state and locality of the grid service devices. In response to receiving a request from a grid device for a particular grid control operation, the grid service controller may then direct the grid device to a particular grid service device capable of providing the particular grid control operation for the grid device based on the state and locality of the grid service devices, accordingly.

Claims

1. A method, comprising:

receiving, at a grid service controller, advertisements from one or more grid service devices, the advertisements indicating one or more grid control operations for which a corresponding grid service device is capable;

maintaining state and locality of the grid service devices;

receiving a request from a grid device for a particular grid control operation; and

directing the grid device to a particular grid service device capable of providing the particular grid control operation for the grid device based on the state and locality of the grid service devices.

2. The method as in claim 1, wherein the grid control operations are distributed, and wherein directing comprises:

directing the grid device to the particular grid service device based on a locality of the grid device in relation to a plurality of grid service devices capable of providing the particular grid control operation.

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

determining that the locality of the grid device in relation to the particular grid service device has changed; and

, in response,

redirecting the grid device to a different grid service device based on the locality of the grid device in relation to the different grid service device.

4. The method as in claim 2, wherein the locality is based on dynamic grid connectivity.

5. The method as in claim 1, further comprising:

determining a state change of the particular grid service device; and

redirecting the grid device to a different grid service device capable of providing the particular grid control operation.

6. The method as in claim 1, wherein the grid device and the grid service devices are each selected from a group consisting of:

primary substation devices;

secondary substation devices;

grid control center devices;

grid monitoring center devices;

grid data center devices;

field area routers; and

grid edge devices.

7. The method as in claim 1, wherein grid control operations consist of grid observability services selected from:

grid intelligence services;

grid state determination services;

grid data management services; and

grid data collection and aggregation services.

8. The method as in claim 7, wherein grid intelligence services are selected from:

operations analytics;

asset analytics;

outage analytics; and

fault analytics.

9. The method as in claim 1, wherein grid control operations consist of grid protection and control services selected from:

grid control federation services;

grid mid-level control services;

grid control disaggregation services; and

grid low-level protection and control services.

10. The method as in claim 9, wherein grid mid-level control services are selected from:

local grid flow control;

direct grid load control; and

transactive/distribution locational marginal pricing (D-LMP)/active load management (ALM) signal propagation.

11. The method as in claim 9, wherein grid low-level protection and control services are selected from:

local grid switching;

local grid feedback; and

grid protection services.

15. The apparatus as in claim 1, wherein grid control operations are selected from:

grid intelligence services;

grid state determination services;

grid data management services;

grid data collection and aggregation services;

grid control federation services;

grid mid-level control services;

grid control disaggregation services; and

grid low-level protection and control services.

12. An apparatus, comprising:

a network interface to communicate with a plurality of grid devices and grid service devices;

a processor coupled to the network interface 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;

receive advertisements from one or more grid service devices, the advertisements indicating one or more grid control operations for which a corresponding grid service device is capable;

maintain state and locality of the grid service devices;

receive a request from a particular grid device for a particular grid control operation; and

direct the particular grid device to a particular grid service device capable of providing the particular grid control operation for the grid device based on the state and locality of the grid service devices.

13. The apparatus as in claim 12, wherein the grid control operations are distributed, and wherein the process when executed to direct is further operable to:

direct the particular grid device to the particular grid service device based on a locality of the particular grid device in relation to a plurality of grid service devices capable of providing the particular grid control operation.

14. The apparatus as in claim 12, wherein the process when executed is further operable to:

determine a state change of the particular grid service device; and

redirect the particular grid device to a different grid service device capable of providing the particular grid control operation.

16. The apparatus as in claim 12, wherein the grid devices and the grid service devices are each selected from a group consisting of:

primary substation devices;

secondary substation devices;

one or more grid devices configured to request grid control operations; and

a grid service controller configured to receive the advertisements, maintain state and locality of the grid service devices, receive a particular request from a particular grid device for a particular grid control operation, and to direct the particular grid device to a particular grid service device capable of providing the particular grid control operation for the grid device based on the state and locality of the grid service devices.

18. The system as in claim 17, wherein the grid control operations are distributed, and wherein the grid service controller is further configured to direct the particular grid device to the particular grid service device based on a locality of the particular grid device in relation to a plurality of grid service devices capable of providing the particular grid control operation.

19. The system as in claim 17, wherein the grid service controller is further configured to determine a state change of the particular grid service device, and redirect the particular grid device to a different grid service device capable of providing the particular grid control operation.

20. The system as in claim 17, wherein the grid devices and the grid service devices are each selected from a group consisting of:

primary substation devices;

secondary substation devices;
