Abstract

The present relates to a method and system for operating a virtual energy network. The method and system receives electricity at a local energy network from an electric grid, stores at an energy storage appliance electricity received from the electric grid at a first period of time, and provides electricity from the energy storage appliance to the local energy network at a second period of time. The cost of the electricity provided by the electric grid is lower at the first period of time than at the second period of time. The energy storage appliance is connected to a management unit via a communication network, from which it receives an energy storage policy. Also, the electric grid, a plurality of energy storage appliances connected to the electric grid and to a corresponding plurality of local energy networks, and the management unit constitute a virtual energy network.

Claims

1. A method for operating a virtual energy network, the method comprising:

receiving electricity at a local energy network from an electric grid;

storing at an energy storage appliance electricity received from the electric grid at a first period of time; and

providing electricity from the energy storage appliance to the local energy network at a second period of time;

wherein the cost of the electricity provided by the electric grid is lower at the first period of time than at the second period of time.

2. The method of claim 1, wherein the energy storage appliance comprises at least one battery for storing the electricity received from the electric grid.

3. The method of claim 1, wherein the energy storage appliance is connected to a management unit via a communication network.

4. The method of claim 3, wherein the energy storage appliance receives an energy storage policy from the management unit.

5. The method of claim 4, wherein the energy storage policy specifies at least one period of time for storing electricity received from the electric grid in the energy storage appliance and at least one period of time for providing the electricity stored in the energy storage appliance to the local energy network.

6. The method of claim 5, wherein the at least one period of time for storing the electricity and the at least one period of time for providing the electricity are determined based on the price of the electricity provided by the electric grid at different periods of time.

7. The method of claim 3, wherein the electric grid, a plurality of energy storage appliances connected to the electric grid and to a corresponding plurality of local energy networks, and the management unit constitute a virtual energy network;

wherein the operations of the plurality of energy storage appliances are controlled by the management unit.

8. The method of claim 3, wherein the energy storage appliance sends a report to the management unit comprising:

a first quantity of electricity received from the electric grid and stored in the energy storage appliance, and a corresponding first time of occurrence; and

a second quantity of electricity provided by the storage energy appliance to the local energy network, and a corresponding second time of occurrence.

9. The method of claim 8, wherein the management unit calculates a bill taking into consideration the first quantity of electricity, the price of electricity when provided by the electric grid at the first time of occurrence, the second quantity of electricity, and the price of electricity when provided by the electric grid at the second time of occurrence.

10. The method of claim 1, wherein the local energy network provides energy used to operate a building;

wherein a building comprises one of;

a house, an individual apartment in a larger building, a building for commercial or professional purposes.

11. A system for operating a virtual energy network, the system comprising:

a local energy network for;

receiving electricity from an electric grid, and

receiving electricity from an energy storage appliance; and

the energy storage appliance for;

storing electricity received from the electric grid at a first period of time, and

providing electricity to the local energy network at a second period of time;

wherein the cost of the electricity provided by the electric grid is lower at the first period of time than at the second period of time.

12. The system of claim 11, wherein the energy storage appliance comprises at least one battery for storing the electricity received from the electric grid.

13. The system of claim 11, wherein the energy storage appliance is connected to a management unit via a communication network.

14. The system of claim 13, wherein the energy storage appliance receives an energy storage policy from the management unit.

15. The system of claim 14, wherein the energy storage policy specifies at least one period of time for storing electricity received from the electric grid in the energy storage appliance and at least one period of time for providing the electricity stored in the energy storage appliance to the local energy network.

16. The system of claim 15, wherein the at least one period of time for storing the electricity and the at least one period of time for providing the electricity are determined based on the price of the electricity provided by the electric grid at different periods of time.

17. The system of claim 13, wherein the electric grid, a plurality of energy storage appliances connected to the electric grid and to a corresponding plurality of local energy networks, and the management unit constitute a virtual energy network;

wherein the operations of the plurality of energy storage appliances are controlled by the management unit.

18. The system of claim 13, wherein the energy storage appliance sends a report to the management unit comprising:

a first quantity of electricity received from the electric grid and stored in the energy storage appliance, and a corresponding first time of occurrence; and

a second quantity of electricity provided by the storage energy appliance to the local energy network, and a corresponding second time of occurrence.

19. The system of claim 18, wherein the management unit calculates a bill taking into consideration the first quantity of electricity, the price of electricity when provided by the electric grid at the first time of occurrence, the second quantity of electricity, and the price of electricity when provided by the electric grid at the second time of occurrence.

20. The system of claim 11, wherein the local energy network provides energy used to operate a building;

wherein a building comprises one of;

a house, an individual apartment in a larger building, a building for commercial or professional purposes.
