Abstract

A method of managing and modulating in real time the electrical consumption of a set of consumers, includes measurement in real time of the electrical consumption of a plurality of targeted sets of electrical equipment in operation, each set of equipment being situated in the home of a consumer, the measurement of the consumption of such equipment being performed by means of an electrical regulation module situated in the home of the consumer. The consumption measurements are transmitted by the modules to a central server. If a global setpoint, at a given moment, indicates that a certain total power should be cancelled, sending by the server, to certain of the modules, the instruction to selectively and temporarily cut the electrical power supply to the electrical equipment. Instruction sent by the server are received and executed by these modules.

Claims

1. A method of managing and modulating in real time the electrical consumption of a set of consumers, said method comprising the steps of:

a) measuring continuously and in real time the electrical consumption of a plurality of targeted sets of electrical equipment in operation, each set of equipment being situated in the home of a consumer, the measurement of the electrical consumption of such equipment being performed individually or overall by means of an electrical regulation module situated in the home of the consumer, each module being directly linked with the electrical power supply circuits of such equipment;

b) transmitting in “

push”

mode by said modules of the electrical consumption measurements to a central server programmed to read and analyze these data;

c) establishing continuously, based on the transmitted electrical consumption measurements, an individual consumption profile of each consumer to deduce therefrom an individual prediction of said each consumer'"'"'s consumption and the available capacities;

d) establishing a global setpoint as a function of said available curtailment capacities, at a given moment, indicating to cancel a certain total power, and sending by said server, to certain of said modules selected according to said global setpoint and the history of the modulations already occurring on each site, of the instruction to selectively and temporarily cut the electrical power supply to the electrical equipment with which the selected modules are linked; and

e) receiving and executing, by these modules, of the instruction sent by said server.

2. The method as claimed in claim 1, further comprising the step of modifying the program of at least one of the electrical regulation modules from the central server.

4. The method as claimed in claim 1, wherein the transmission of the data from the modules to the central server is performed by means of wired or wireless switched networks, or by packet data transmission according to the IP protocol over wired or wireless networks.

5. The method as claimed in claim 1, further comprising the step of incorporating measurement data complementing the electrical consumption of the targeted sets of electrical equipment, or of all or part of the electrical equipment of the consumer, said measurement being performed by measuring devices other than the electrical regulation module and with which a link to the latter is established.

3. The method as claimed in claim l, wherein each electrical regulation module operates in a stand-alone manner relative to the other modules and relative to the other elements of the electrical installation of the site.

6. A system for managing and modulating in real time the electrical consumption of a set of consumers, said system comprising:

a central server;

a plurality of electrical regulation modules, each module being directly linked, continuously, with the electrical power supply circuits of electrical equipment forming part of a targeted set, said targeted set of electrical equipment and said module being located in the home of a consumer, said module being programmed to measure and retain the electrical consumption data of each targeted set in real time, transmit said data to said central server, receive and execute instructions from said central server;

means for transmitting in push mode said electrical consumption data from said modules to the central server;

said central server comprising means for reading and analyzing the data transmitted by said modules, means for establishing continuously, based on the transmitted electrical consumption data, an individual consumption profile of each consumer to deduce therefrom an individual prediction of said each consumer'"'"'s consumption and the available capacities, means for transmitting to certain of said modules instructions to selectively and temporarily cut the electrical power supply to the electrical equipment with which they are linked, in order to satisfy a global setpoint, at a given moment, to cancel a certain total power, wherein said global setpoint is established as a function of said available capacities and said modules are selected according to said global setpoint and the history of the modulations already occurring on each site;

means for transmitting instructions from the central server to said modules; and

means for selectively and temporarily cutting the electrical power supply to the electrical equipment.

7. The system as claimed in claim 6, wherein the central server comprises means for modifying the program of each electrical regulation module.

8. The system as claimed in claim 6, wherein each electrical regulation module is formed of one or several elements.

9. The system as claimed in claim 6, wherein the means of transmitting data from the modules to the central server are wired or wireless switched networks, or means of packet data transmission over wired or wireless networks.

10. The system as claimed in claim 6, further comprising measuring devices able to supply measurement data complementing the electrical consumption of the targeted sets of electrical equipment or of all or part of the electrical installation of the consumer, said devices being different from the electrical regulation modules and each device being linked with one of said modules.
