Abstract

A system by which an electric power utility can selectively limit power supplied to homeowners or other users to conserve electricity in periods of higher usage/shortages. Each home that is participating in the system has “smart switches” installed at outlet locations, for example, a stove, clothes dryer, television sets, lamp, etc. The power utility sends communications either through cell phone technology, telephone, or other communication link to the home to signal the various smart switches to limit electrical output (either blocking current flow totally, or periodically). The electric utility sends its communication to a monitoring and control computer which in turn controls the various smart switches. Also, information of power usage is transmitted to the smart switches back to the utility company so that bills can be prepared, with savings also specified in the bill.

Claims

1. A system to monitor and control power usage where:

a) there is a power provider which provides power to a plurality of power user facilities in an operating area of the power provider;

b) a plurality of participating power user facilities each having a facility power distribution network which comprises a main power receiving connection to receive power from the power provider and deliver power to a plurality of outlet locations of the participating power user facility; and

,

c) there are at least at some of said outlet locations power using components to receive power from its facility power distribution network at such power locations;

said system comprising;

a) each of said participating facilities having a plurality of monitoring/switching units, each of which has an operative connection to the power distribution network for a related outlet location, and being arranged to receive control signals to stop or permit current flow from its related location outlet, each monitoring/switching unit also being arranged to monitor current flow from its related outlet location and to transmit information signal(s) related to said current flow;

b) a power provider control section arranged to transmit provider control signals to of each participating facility to selectively stop current flow or permit current flow at one or more selected outlet locations, and to receive information from each participating facility relating to electric power usage in the participating power user facility.

c) each of said participating facilities having a monitoring/control section having operative connections to said monitoring/switching units and to said power provider control section said monitoring/control section being arranged to be able to;

i. to receive information relating to current flow at each of said monitoring switching units;

ii. to present at said monitoring control section said information relating to current flow at each monitoring/switching unit so as to be selectively observable at said monitoring/control section relative power usage and time periods of usage;

iii. to communicate with said power provider control section to acquire information relating to power delivered and/or to be delivered at the participating facility in a manner that the information from the power provider control section is observable at the participating facility;

iv. to be able to be operated to initiate at each of said monitoring control section control signals relating to initiating and terminating periods during which current is to be delivered to selected monitoring/switching units.

2. The system as recited in claim 1, wherein said power provider control section and said facility monitoring/control section transmit and receive signal between one another by way of electromagnetic wave communication, telephone communication, or a combination of electromagnetic wave communication and telephone communication.

3. The system as recited in claim 1, wherein said power provider control section and said facility monitoring/control section, send and receive signals between one another by electromagnetic communication.

4. The system as recited in claim 1, wherein said power provider control section and said facility monitoring/control section, send and receive signals between one another by telephone communication.

5. The system as recited in claim 1, wherein said monitoring/switching units and the facility monitoring/control section exchange and receive signal between one another by communicating over the power distribution network of the facility.

6. The system as recited in claim 1, wherein said monitoring/switching units and the facility monitoring/control section exchange and receive signal (s) between said power provider control sections and said monitoring/control sections to establish a structure for “

Pre-Paid”

power consumption by having the consumer pre pay for “

Consumer Power Credits”

(CPC) for the purchase of known amount of power at a known price per kilowatt.

7. The system as recited in claim 1, wherein said monitoring/switching units and the facility monitoring/control section exchange and receive signal (s) between one another by communicating over the fiber optic cables using Ethernet technology.

8. The system as recited in claim 1, wherein said monitoring/control section comprises a monitoring control unit and an information output unit to initiate communication with said power providing control section to initiate signals to said monitoring/switching units relative to stopping and permitting current to said monitoring/switching units.

9. The system as recited in claim 8, wherein said power providing control section causes power to be delivered to said monitoring/switching units in accordance with a prearrangement as to which outlet locations at the participating facility has power curtailed for a period of time and said information output unit is able to by-pass and/or restructure said prearrangement of current flow being permitted or stopped.

10. The system as recited in claim 8, wherein said information output unit comprises a keyboard.

11. The system as recited in claim 9, wherein said information output unit comprises a keyboard.

12. The system as recited in claim 1, wherein said monitoring control section comprises a monitoring/control unit and a visual communication unit to display information transmitted to said monitoring/control unit.

13. The system as recited in claim 12, wherein said visual communication unit comprises a visual display, or a printer, or both a visual display and a printer.

14. The system as recited claim 8, wherein the power provider control section comprises a computer program arranged to cause control signals to be transmitted to said participating facility in accordance with a pre-arrangement, and said information output unit is arranged to be able to modify said program in accordance with instructions from said information output unit of the monitoring control section of that participating facility.

15. The system as recited in claim 8, wherein said information output unit comprises a keyboard arranged to request information from said power providing control section and to request data from said monitoring/switching units and to initiate communications for modifying a computer program at said power providing control section to modify said program in accordance with instructions initiated from said monitoring/control section at the participating facility.

16. The system as recited in claim 1, wherein at least some of said participating facilities is able to terminate its participation in the system by deactivating communication with the power provider control section and causing all of the monitoring switching units in that facility to go to or remain at a current transmitting mode of operation.

17. The system as recited in claim 1, wherein the monitoring/control section has a information receiving capability to receive information from the power providing control system and providing an alert signal for the monitoring/control section.

18. The system as recited in claim 17, wherein said alert signal comprises an audio signal, or a visual signal, or both an audible and visual signal.

19. The system as recited in claim 18, wherein said monitoring/control section comprises a credit card reading unit by which payment of power bills and/or other financial related transactions can be initiated through a communication channel between said monitoring/control section and the power providing control section.

20. The system as recited in claim 1, wherein said monitoring/control section communicates through electric power lines in the facility to communicate with the monitoring switching units in the participating facility.
