Abstract

The operation of a power distribution network is modeled. At least one quality of the operation of the power distribution network is measured. The future operational performance of the power distribution network is predicted based at least in part upon the modeling. When the at least one measure of the quality of the operation of the power distribution network or the predicted future operational performance do not meet the predetermined performance criteria, corrective action is taken with respect to the power distribution network.

Claims

1. A method for optimizing power quality in a power distribution network, the method comprising:

modeling an operation of a power distribution network;

measuring at least one characteristic associated with at least one of a cleanliness of power of the power distribution network or a reliability of power of the power distribution network;

determining whether the at least one characteristic meets a first predetermined performance criteria;

predicting a future operational performance of the power distribution network based at least in part upon the modeling and determining whether the future operational performance meets a second predetermined performance criteria;

in response to determining the at least one characteristic associated with the operation of the power distribution network does not meet the first predetermined performance criteria or the predicted future operational performance of the power distribution network does not meet the second predetermined performance criteria, taking a corrective action with respect to the power distribution network to improve at least one of the cleanliness of power of the power distribution network or the reliability of power of the power distribution network.

2. The method of claim 1 wherein taking a corrective action comprises removing and replacing a component of the power distribution network.

3. The method of claim 1 wherein taking a corrective action comprises deactivating a component of the power distribution network.

4. The method of claim 1 wherein the power distribution network is positioned in a home and further comprising coupling at least one appliance to the power distribution network.

5. The method of claim 4 further comprising determining an adjustment of an operation of the at least one appliance connected in the power distribution network and communicating the adjustment to the at least one appliance utilizing an existing component of the power distribution network.

6. The method of claim 4 wherein the appliance is selected from the group consisting of a television, a radio, a refrigerator, an oven, a microwave, a washer, and a dryer.

7. The method of claim 1 further comprising presenting a choice of the corrective action to a user.

8. The method of claim 1 further comprising offering a reward for taking a corrective action.

9. An apparatus for optimizing power quality, the apparatus comprising:

an interface having an input and output;

a memory comprising a model of a power distribution network;

a processor coupled to the interface and the memory, the processor arranged and configured to;

model an operation of a power distribution network using the model in memory,

determine whether a characteristic associated with at least one of a cleanliness of power of the power distribution network or a reliability of power of the power distribution network received via the input of the interface meets a first predetermined performance criteria,

predict a future operational performance of the power distribution network based at least in part upon the model,

determine whether the future operational performance meets a second predetermined performance criteria,

in response to determining that the at least one characteristic of the power distribution network does not meet the first predetermined performance criteria or the future operational performance does not meet the second predetermined performance criteria, transmit a signal instigating a corrective action to improve at least one of the cleanliness of power of the power distribution network or the reliability of power of the power distribution network.

10. The apparatus of claim 9 wherein the instigating a corrective action comprises transmitting a signal at the output to automatically alter the operation of at least one consumer device.

11. The apparatus of claim 9 wherein the instigating a corrective action comprises presenting a corrective action to a user and receiving user input as to the corrective action to take.

12. The apparatus of claim 9 wherein the apparatus is disposed within an appliance in a building.

13. The apparatus of claim 12 wherein the appliance is selected from the group consisting of a television, a radio, a refrigerator, an oven, a microwave, a washer, and a dryer.

14. The apparatus of claim 9 wherein the output of the interface is coupled to at least one power line to communicate with another apparatus.

15. The apparatus of claim 9 wherein the apparatus comprises a device separate from an existing component of the power distribution network.

16. The apparatus of claim 9 wherein the output of the interface is coupled to at least one power line, the power line coupled to an appliance.

17. The apparatus of claim 9 wherein the processor is further configured to offer a reward to a user for taking a corrective action.
