Abstract

A computer-implemented method, a controller, and a Software Defined Network (SDN) perform steps of correlating users based on unique identifiers to service addresses; receiving historical data from associated control area operator for the service addresses; correlating the users' bandwidth usage behavior to the users' power usage behavior; monitoring the users' bandwidth usage over time; characterizing bandwidth usage type for the users with abnormal bandwidth usage patterns; and notifying the control area operator of the users with the abnormal bandwidth usage patterns based on the characterized bandwidth usage type. Accordingly, electric power forecasting by the control area operator can include improved accuracy through correlating the users' bandwidth usage behavior and detecting abnormal conditions.

First claim

What is claimed is:

1. A computer-implemented method, comprising:
monitoring bandwidth usage for a plurality of users in a Software Defined Network (SDN) network, wherein the plurality of users correspond to service addresses in a control area of an electric grid system;
detecting abnormal bandwidth usage for a time period for one or more users of the plurality of users on the SDN network, which is a service provider network separate from the electric grid system;
determining whether the abnormal bandwidth usage for the one or more users indicates a power forecast adjustment is needed for the one or more users, wherein the determining is based on correlating bandwidth usage behavior for the plurality of users to power usage behavior for the plurality of users and basing the power forecast adjustment thereon;
notifying an operator of the control area of the power forecast adjustment based on the determining such that the operator adjusts power generation based on the notifying, wherein the plurality of users comprises a subset of users in the control area, and wherein the operator utilizes statistical sampling based on the notifying for the power forecast adjustment;
characterizing bandwidth usage type for the one or more users; and
detecting a condition of the one or more users based on the characterizing, wherein the condition comprises any of home on a work day, home from school on a school day, away from home, and returning to home.

2. The computer-implemented method of claim 1 , further comprising:
receiving historical data from the operator of the control area for the plurality of users.

3. The computer-implemented method of claim 1 , further comprising:
correlating the plurality of users based on unique identifiers in the SDN network to the service addresses for the control area.

4. The computer-implemented method of claim 3 , wherein the unique identifiers comprise any of Internet Protocol addresses, Media Access Control Address, and Virtual Local Area Network identifiers.

5. The computer-implemented method of claim 1 , wherein the computer-implemented method is implemented by a controller operating an SDN application.

6. A controller, comprising:
a network interface, a data store, and a processor, each communicatively coupled therebetween; and
memory storing instructions that, when executed, cause the processor to:
monitor bandwidth usage for a plurality of users in a Software Defined Network (SDN) network, wherein the plurality of users correspond to service addresses in a control area of an electric grid system;
detect abnormal bandwidth usage for a time period for one or more users of the plurality of users on the SDN network, which is a service provider network separate from the electric grid system;
determine whether the abnormal bandwidth usage for the one or more users indicates a power forecast adjustment is needed for the one or more users, wherein the power forecast adjustment is determined based on a correlation of bandwidth usage behavior for the plurality of users to power usage behavior for the plurality of users and the power forecast adjustment is based thereon;
notify an operator of the control area of the power forecast adjustment based on the abnormal bandwidth usage such that the operator adjusts power generation based on the notifying, wherein the plurality of users comprises a subset of users in the control area, and wherein the operator utilizes statistical sampling based on the notification for the power forecast adjustment
characterize bandwidth usage type for the one or more users; and
detect a condition of the one or more users based on the characterized bandwidth, wherein the condition comprises any of home on a work day, home from school on a school day, away from home, and returning to home.

7. The controller of claim 6 , wherein the instructions that, when executed, further cause the processor to:
receive historical data from the operator of the control area for the plurality of users.

8. The controller of claim 6 , wherein the instructions that, when executed, further cause the processor to:
correlate the plurality of users based on unique identifiers in the SDN network to the service addresses for the control area.

9. The controller of claim 8 , wherein the unique identifiers comprise any of Internet Protocol addresses, Media Access Control Address, and Virtual Local Area Network identifiers.

10. The controller of claim 6 , wherein the controller comprising an SDN controller operating SDN applications.

11. A Software Defined Network (SDN), comprising:
a plurality of network elements comprising switch hardware providing network access to a plurality of users each uniquely identified by a unique identifier; and
a server operating an SDN application and communicatively coupled to the plurality of network elements;
wherein the SDN application is configured to:
monitor bandwidth usage for the plurality of users, wherein the plurality of users correspond to service addresses in a control area of an electric grid system;
detect abnormal bandwidth usage for a time period for one or more users of the plurality of users on the SDN network, which is a service provider network separate from the electric grid system;
determine whether the abnormal bandwidth usage for the one or more users indicates a power forecast adjustment is needed for the one or more users, wherein the power forecast adjustment is determined based on a correlation of bandwidth usage behavior for the plurality of users to power usage behavior for the plurality of users and the power forecast adjustment is based thereon;
notify an operator of the control area of the power forecast adjustment based on the abnormal bandwidth usage such that the operator adjusts power generation based on the notifying, wherein the plurality of users comprises a subset of users in the control area, and wherein the operator utilizes statistical sampling based on the notification for the power forecast adjustment
characterize bandwidth usage type for the one or more users; and
detect a condition of the one or more users based on the characterized bandwidth, wherein the condition comprises any of home on a work day, home from school on a school day, away from home, and returning to home.
