Abstract

A method and system for dynamically routing electric power in real time in accordance with parameters submitted by buyers and sellers of electric power using a feedback control scheme. A control node is arranged for receiving the parameters via a wide area network and to generate a route plan based on the parameters as well as current supply and demand in a network. The control node is also connected to the transmission and distribution systems to dynamically route electric power between matched buyers and sellers to effect the route plan.

Claims

1. A method for dynamically distributing electric power in an electric network having distribution networks, comprising the steps of:

(a) receiving by a control node bids and asks of electric power and a signal from one or more feedback sensors related to current supply and demand conditions on an electric network including power consumption by end users through a feedback loop;

(b) matching by the control node the bids and asks; and

(c) generating by the control node a route plan for delivering electric power between buyers and sellers based on the matched bids and asks, the signal from the one or more feedback sensors received through the feedback loop, and at least one of price, quality of service, and class of service, the route plan adjusting power flow to the electric network to balance load and resources on the electric network.

2. The method of claim 1, wherein the control node is incorporated in an electrical substation.

3. The method of claim 1, wherein said step (a) further comprises receiving bids and asks in a spot market.

4. The method of claim 1, wherein said step (a) comprises receiving bids and asks via a wide area network.

5. The method of claim 4, wherein said step (a) comprises inputting the bids and asks to the wide area network via respective buyer on-site devices and seller on-site devices.

6. The method of claim 1, further comprising the step (d) of receiving current supply and demand conditions on an electric network via a feedback loop and using the current supply and demand for dynamically matching the bids and asks.

7. The method of claim 6, wherein said step (c) further comprises generating a route plan for each of the matches using the current supply and demand conditions.

8. The method of claim 6, wherein said step (b) comprises continuously updating the matches based on changes in the bids and asks.

9. The method of claim 1, wherein said step (b) comprises continuously updating the matches based on changes in the bids and asks.

10. The method of claim 9, wherein said step (b) further comprises matching an equal share of the electric power from a seller with the lowest asking price to all bids of buyers to which the electric power is available.

11. The method of claim 9, wherein said step (b) further comprises matching a share of the electric power from a seller with the lowest asking price to all bids of buyers to which the electric power is available, wherein the share is proportional to the amount of electric power demanded by the buyers.

12. The method of claim 9, wherein said step (b) further comprises matching the ask from a seller with the lowest asking price first to the bids of buyers with the highest amount of electric power demanded.

13. The method of claim 1, wherein the bids and asks matched by the control node form settled trades between buyers and sellers.

14. The method of claim 1, wherein the route plan is transmitted to a central control of an electric power transmission network.

15. The method of claim 14, wherein the central control effects the route plan by controlling addressable switches.

16. The method of claim 15, wherein the addressable switches are provided with unique identification codes for identifying their locations on the electric network.

17. The method of claim 16, wherein the addressable switches are provided at input to each distribution network so that the control node can route electric power to one or more distribution networks in accordance with the route plan.

18. The method of claim 14, wherein the electric power transmission network uses high voltage direct current.

19. The method of claim 18, further comprising the step of providing AC/DC conversion for converting between direct current and alternating current.

20. The method of claim 14, wherein the electric transmission network uses resonant energy transmission technology.

21. The method of claim 1, further comprising the step of determining by the control node whether a matched bid and ask is possible based on supply and demand information relating to an electric network.

22. The method of claim 21, wherein the supply and demand information is provided to the control node by the central control of the electric network.

23. The method of claim 21, wherein the supply and demand information is provided to the control node by one of wireline and wireless transceivers.

24. The method of claim 23, wherein the supply and demand information is provided to the control node via a power line.

25. The method of claim 24, wherein the supply and demand information is transmitted using BPL protocol.

26. The method of claim 24, wherein the supply and demand information is transmitted using wireless access points.

27. The method of claim 1, wherein the class of service or quality of service includes at least one of reliability index and voltage variances.

28. A system for dynamically distributing electric power in an electric network having distribution systems, comprising:

a control node that includes at least one processor and memory combined with the at least one processor, the control node for (a) receiving bids and asks of electric power and a signal from one or more feedback sensors related to current supply and demand conditions on an electric network including power consumption by end users through a feedback loop, (b) matching the received bids and asks, and (c) generating a route plan for delivering electric power between buyers and sellers based on the matched bids and asks, the signal from the one or more feedback sensors received through the feedback loop, and at least one of price, quality of service, and class of service, the route plan adjusting power flow to the electric network to balance load and resources on the electric network.

29. The system of claim 28, wherein said control node is connectable to a wide area network for receiving the bids and asks from buyers and sellers.

30. The system of claim 28, wherein said control node comprises a deal maker module for matching said bids and asks and a route planner module for planning a route for effecting the matched bids and asks.

31. The system of claim 30, wherein said control node comprises an accounting module connectable for determining the actual usage of the buyer and determining the charge to the buyer.

32. The system of claim 28, further comprising:

A switch node in operative communication with the control node for switching electric power between in accordance with the route plan.

33. The system of claim 32, wherein the switch node is located at the input to a distribution system.

34. The system of claim 32, wherein the switch node includes addressable switches that are addressable by unique identification codes indicative of locations of the addressable switches in the electric network so that the control node can readily identify the locations of the addressable switches.
