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 trading and distributing electric power, comprising the steps of:

(a) collecting by a control node parameters including bids and asks from buyers and sellers of electric power;

(b) substantially continually monitoring energy consumption and generation by the buyers and sellers; and

(c) dynamically transmitting electric power via a High Voltage Direct Current transmission (HVDC) network between buyers and sellers by switch nodes responsive to the control node based on the collected parameters, and forming legally binding contractual relationships between the buyers and sellers.

2. The method of claim 1, wherein said step (c) includes real time switching the flow of electric power in the HVDC network based on power supply and demand.

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

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

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

6. The method of claim 5, 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.

7. The method of claim 1, wherein said step (c) comprises configuring an electric network comprising a high voltage direct current system.

8. The method of claim 1, wherein said step (b) comprises receiving current supply and demand conditions on the electric network via a feedback loop and using the current supply and demand for dynamically matching buyers and sellers.

9. The method of claim 8, wherein said step (c) further comprises generating a route plan for each of the matches using the current supply and demand conditions.

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

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

12. The method of claim 11, wherein said step (b) further comprises matching an equal share of the power from a seller with the lowest asking price to all bids of buyers to which the power is available.

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

14. The method of claim 11, 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 power demanded.

15. A system for dynamically distributing electric power, comprising a control node for continuously receiving bids and asks from buyers and sellers, matching the received bids and asks to form matched bids and asks and dynamically updating the matched bids and asks in accordance with changes occurring in the bids and asks, said control node being connectable to an electric network capable of routing electric power between buyers and sellers and for activating switching devices connected to said electric network for switching a flow of power in the electric network to effect the matching of the bids and asks.

16. The system of claim 15, wherein said control node is connectable to a wide area network for receiving the bids and asks from buyers and sellers.

17. The system of claim 15, 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.

18. The system of claim 17, wherein said control node comprises an accounting module connectable for determining the actual usage of the buyer and determining the charge to the buyer.
