Abstract

An electrical system includes at least one power port and at least one monitoring and control device that is coupled to the power port. The monitoring and control device includes a load control module configured to control an amount of electrical power transmitted to at least one electrical load. The load control module is further configured to receive a power control command from a power system and to transmit a power control acknowledgement to the power system.

Claims

1. An electrical system, comprising:

at least one power port; and

an electrical socket coupled to the at least one power port, wherein the electrical socket includes a housing, at least one opening oriented to receive at least one power cord from at least one electrical load, and at least one monitoring and control device positioned within said housing, said at least one monitoring and control device comprising;

a load control module configured to control an amount of electrical power transmitted to the at least one electrical load, said load control module further configured to;

receive a power control command from a power system;

transmit a power control acknowledgement to the power system; and

implement the power control command after transmitting the power control acknowledgment.

2. An electrical system in accordance with claim 1, wherein said at least one monitoring and control device further comprises a communication module configured to be communicatively coupled to the power system.

3. An electrical system in accordance with claim 2, further comprising a wireless data transceiver, wherein said communication module communicates with the power system through said wireless data transceiver.

4. An electrical system in accordance with claim 2, further comprising a wired data transceiver, wherein said communication module communicates with the power system through said wired data transceiver.

5. An electrical system in accordance with claim 1, wherein said at least one monitoring and control device further comprises at least one of a voltmeter, an ammeter, and a wattmeter configured to be coupled to the at least one electrical load.

6. An electrical system in accordance with claim 1, wherein said load control module provides a variable voltage and a variable current to the at least one electrical load.

7. An electrical system in accordance with claim 1, wherein said electrical socket receives at least one power cord from at least one legacy appliance, and wherein said load control module is configured to control an electrical load delivered to said at least one legacy appliance.

8. An electrical system in accordance with claim 1, further comprising a load monitoring module configured to:

determine an amount of electrical power transmitted to the at least one electrical load; and

transmit a value representing the determined amount of electrical power to the power system.

9. An electrical system in accordance with claim 1, wherein said load control module further is configured to implement the power control command on the at least one electrical load.

10. A power system, comprising:

at least one electrical load;

a control unit; and

at least one electrical socket configured to be coupled to said control unit and to said at least one electrical load, said at least one electrical socket comprising;

a housing;

at least one opening oriented to receive at least one Dower cord from electrical load; and

a load control module positioned within said housing, and configured to control an amount of electrical power transmitted to said at least one electrical load, said load control module further configured to;

receive a power control command from said power system;

transmit a power control acknowledgement to said power system; and

implement the power control command after transmitting the power control acknowledgment.

11. A power system in accordance with claim 10, wherein said at least one electrical socket further comprises a communication module configured to be communicatively coupled to said control unit.

12. A power system in accordance with claim 11, further comprising a wireless data transceiver, wherein said communication module communicates with said control unit through said wireless data transceiver.

13. A power system in accordance with claim 11, further comprising a wired data transceiver, wherein said communication module communicates with said control unit through said wired data transceiver.

14. A power system in accordance with claim 10, wherein said at least one electrical socket comprises at least one of a voltmeter, an ammeter, and a wattmeter configured to be coupled to said at least one electrical load.

15. A power system in accordance with claim 10, wherein said load control module transmits a variable voltage and a variable current to said at least one electrical load.

16. A power system n accordance with claim 10, wherein said electrical socket receives at least one power cord from at least one legacy appliance, and wherein said load control module is configured to control an electrical load delivered to said at least one legacy appliance.

17. A power system in accordance with claim 10, wherein said at least one electrical socket further comprises a load monitoring module configured to:

determine an amount of electrical power transmitted to said at least one electrical load; and

transmit a value representing the determined amount of electrical power to said power system.

18. An electrical socket, comprising:

a housing;

at least one opening oriented to receive at least one power cord from a first electrical load; and

a first load control module positioned within said housing, and configured to control an amount of electrical power transmitted to said first electrical load, said load control module further configured to;

receive a power control command from a power system;

transmit a power control acknowledgement to the power system; and

implement the power control command after transmitting the power control acknowledgment.

19. An electrical socket in accordance with claim 18, further comprising a second load control module positioned within said housing, and configured to control an amount of electrical power transmitted to a second electrical load.

20. An electrical socket in accordance with claim 18, further comprising a load monitoring module configured to determine an amount of electrical power transmitted to the first electrical load.
