Abstract

In one embodiment, a layered/distributed grid-specific network services system comprises grid sensors in the utility grid configured to generate grid data values such as raw grid data values, processed grid data values, and/or any combination thereof, and to communicate the grid data values using a communication network. Distributed grid devices in the utility grid may be configured to receive the grid data values, and one or more of the grid devices may be configured to convert raw grid data values into processed grid data values. Application devices in the utility grid may be configured to access the grid data values from the distributed grid devices, and to further process the grid data values according to a particular grid application operating at the corresponding application device into application data values.

First claim

a plurality of application devices in the utility grid configured to access the converted grid data values from the distributed grid devices, wherein the converted grid data values are further processed by a particular grid application operating at the corresponding application device into application data values.

2. The system as in claim 1 , further comprising:
one or more grid control devices in the utility grid configured to access and analyze the converted grid data values and/or the application data values, and to determine a grid control response.

3. The system as in claim 1 , wherein one or more of the plurality of distributed grid devices are further configured to store the converted grid data values.

4. The system as in claim 1 , wherein one or more of the plurality of distributed grid devices are further configured to dynamically distribute the converted grid data values to the plurality of application devices.

5. The system as in claim 1 , wherein one or more of the plurality of application devices further process the converted grid data values according to a complex event processing (CEP) model to generate the application data values.

6. The system as in claim 5 , wherein the application data values represent a state and locality of at least a portion of the utility grid.

7. The system as in claim 1 , wherein the plurality of application devices are further configured to dynamically distribute the converted grid data values and/or the application data values to the one or more grid control devices.

8. A method, comprising:
receiving, at a particular device of a plurality of distributed grid devices in the utility grid, a plurality of raw grid data values from a plurality of grid sensors;
converting, at the particular device, the raw grid data values into layered network services that are universally available to different types of utility grid applications; and
communicating, by the particular device, the converted plurality of grid data values with a plurality of application devices in the utility grid, the plurality of application devices configured to access the grid data values from the distributed grid devices.

9. The method as in claim 8 , further comprising:
storing one or more of the converted grid data values.

10. The method as in claim 8 , wherein converting includes:
converting the raw grid data values into application data values.

11. The method as in claim 8 , further comprising:
dynamically distributing the converted grid data values to one or more grid control devices.

12. A method, comprising:
accessing, via a network interface on an utility grid application device in a utility grid, a plurality of distributed grid devices in the utility grid;
receiving a plurality of grid data values from the distributed grid devices at the utility grid application device, wherein the plurality of grid data values have been converted from raw data values into layered network services that are universally available to different types of utility grid applications; and
executing a particular grid application operating at the utility grid application device to further process the grid data values.

13. The method as in claim 12 , further comprising:
communicating the plurality of grid data values and/or application data values to one or more grid control devices in the utility grid configured to access and analyze the grid data values and/or the application data values, and to determine a grid control response.

14. The method as in claim 12 , further comprising:
storing the plurality of grid data values and/or application data values.

15. The method as in claim 12 , wherein the grid data values are processed according to a complex event processing (CEP) model to generate the application data values.

16. The method as in claim 12 , wherein the application data values represent a state and locality of at least a portion of the utility grid.

17. An apparatus, comprising:
