Abstract

Systems and methods are described for a power aggregation system. In one implementation, a service establishes individual Internet connections to numerous electric resources intermittently connected to the power grid, such as electric vehicles. The Internet connection may be made over the same wire that connects the resource to the power grid. The service optimizes power flows to suit the needs of each resource and each resource owner, while aggregating flows across numerous resources to suit the needs of the power grid. The service can bring vast numbers of electric vehicle batteries online as a new, dynamically aggregated power resource for the power grid. Electric vehicle owners can participate in an electricity trading economy regardless of where they plug into the power grid.

Claims

1. A method of inputting and displaying information in a power aggregation system, comprising:

associating a user interface with an electric resource;

interacting with a user or owner of the electric resource via the user interface, wherein the electric resource comprises an electric vehicle, and wherein the user or owner controls a degree of participation of the electric resource in power aggregation via the user interface; and

,

displaying parameters of the power aggregation system on the user interface;

wherein constraints and/or preferences to be input and/or the parameters to be displayed include at least one of;

an energy pricing preference of an owner of the electric resource, a vehicle state-of-charge, a predicted amount of time until the electric resource disconnects from a power grid, a preference of the owner of the electric resource for revenue over a state-of-charge quality of the electric resource, electrical limits of the electric resource, and user-selectable manual charging overrides of the power aggregation system.

2. The method as recited in claim 1, wherein the user interface inputs user-selected power aggregation constraints and user-selected power aggregation preferences via the user interface.

3. The method as recited in claim 1, wherein the user interface inputs and displays information regarding the electric vehicle.

4. The method as recited in claim 1, wherein the user interface comprises an in-vehicle user interface, a charging station user interface, a web-based user interface, or a cell phone user interface.

5. The method as recited in claim 1, wherein the user interface is accessible online by an owner of the electric vehicle.

6. The method as recited in claim 1, wherein the user interface extends access to a user account of the power aggregation system via a password.

7. The method as recited in claim 1, wherein the user interface is extended by the power aggregation system over a same communication channel that the power aggregation system uses to signal the electric resource to provide power to a power grid or take power from a power grid.

8. The method as recited in claim 1, wherein the user interface is extended by the power aggregation system over the Internet or over a wireless medium.

9. The method as recited in claim 1, wherein communication between the electric resource and the power aggregation system is encrypted.

10. The method as recited in claim 1, wherein the user interface displays checkboxes, icons, and/or menus for user-selection of preferences, constraints, customizations, and optimizations of the power aggregation system with respect to system parameters, electric resource parameters, and electric resource/power aggregation system interactions.

11. The method as recited in claim 1, wherein the user interface advertises energy prices and offers to participate in power aggregation to a user and securely obtains commitments from the user.

12. The method as recited in claim 1, wherein the electric resource comprises an electric vehicle and the user interface displays distance driven, electrical and non-electrical fuel usage, and overall vehicle efficiency with respect to energy use, expense, and environmental impact.

13. The method as recited in claim 12, wherein the user interface further comprises an override for requesting immediate charging of the electric vehicle.

14. The method as recited in claim 1, wherein the power aggregation system learns behavior of the electric vehicle and learns user behavior via the user interface and adapts a charging timing automatically.

15. An operator interface for a power aggregation system, comprising:

a display displaying parameters of the power aggregation system on a user interface;

an input device;

display objects, which when selected by the input device provide an operator access to operations of the power aggregation system, including electrical resource control, bidding and contract with energy markets and power grid operators, load protection, constraint optimization, data storage, and resource owner interaction, wherein the operator controls a degree of participation of an electric resource in power aggregation via the operator interface;

wherein constraints and/or preferences to be input and/or the parameters to be displayed include at least one of;

an energy pricing preference of an owner of the electric resource, a vehicle state-of-charge, a predicted amount of time until the electric resource disconnects from a power grid, a preference of the owner of the electric resource for revenue over a state-of-charge quality of the electric resource, electrical limits of the electric resource, and user-selectable manual charging overrides of the power aggregation system.

16. The operator interface for a power aggregation system as recited in claim 15, further comprising a map of power aggregation activity across at least part of the power aggregation system.
