Abstract

A method of monitoring an electrical installation comprising electrical feeders for powering devices in a regulated manner. The method comprises the steps of: consultation of a history of curtailments carried out on the feeders; as a function of the history consulted, determination for each of the feeders of a level of participation in a general electrical regulation of the installation; association of a curtailment priority rank with each of the participation levels determined for each of the feeders; and following the reception of a setting for general electrical regulation of the installation, curtailment of the feeders in order of priority rank.

Claims

1. A method for controlling an electrical installation comprising electrical feeders for supplying power to devices in a regulated manner, the method comprising:

consulting a history of curtailments applied to said feeders;

based on the consulted history, determining for each of the feeders a level of participation in a general electrical regulation of said installation;

associating a curtailment priority rank with each of the levels of participation determined for each of said feeders;

after receiving a setting for general electrical regulation of said installation, ordering a curtailment of said feeders according to their priority rank; and

terminating curtailment of said curtailed feeders, with the termination of curtailment for each feeder being distributed over time so as to distribute a load restoration to said feeders over time with a gradual readdition of the feeders, avoiding thus a rebound effect consisting of a sudden and simultaneous power draw when said curtailment is terminated.

2. The method according to claim 1, wherein the feeders are curtailed by order of their priority rank at least until a general electric regulation of the installation corresponding to said setting is achieved.

3. The method according to claim 1, wherein said distribution over time is based on the curtailment priority ranks associated with the levels of participation of said feeders.

4. The method according to claim 3, wherein said distribution over time is random.

5. The method according to claim 1, further comprising collecting data from at least one current sensor associated with at least one of said feeders, said sensor measuring power consumption of the associated feeder, said level of participation of the associated feeder being also determined on the basis of the collected data.

6. The method according to claim 1, wherein said level of participation of at least one feeder is further determined according to the frequency of an electrical signal supplied by an electrical grid to which said installation is connected.

7. The method according to claim 1, further comprising collecting data from at least one home sensor measuring an environmental condition of the installation, said level of participation of the associated feeder being further determined on the basis of the collected data.

8. The method according to claim 1, wherein at least one of said devices is a heat exchanger and communicates data on the temperature reached by the device, said level of participation of the feeder powering the device being further determined on the basis of said temperature data.

17. A non-transitory computer program product comprising instructions readable by a processor of an electrical installation, said processor implementing the method according to claim 1 when said instructions are executed by said processor.

9. An electrical installation comprising electrical feeders for supplying power to devices in a regulated manner, said installation comprising at least:

a database adapted for storing a history of curtailments applied to said feeders;

a receiver for receiving a setting for general electrical regulation of said installation;

a data processor adapted for;

determining for each of the feeders, on the basis of the history, a level of participation in a general electrical regulation of said installation;

associating a curtailment priority rank with each of the levels of participation determined for each of said feeders;

curtailing said feeders according to their priority rank; and

terminating curtailment of said curtailed feeders, with the termination of curtailment for each feeder being distributed over time so as to distribute a load restoration to said feeders over time with a gradual readdition of the feeders, avoiding thus a rebound effect consisting of a sudden and simultaneous power draw when said curtailment is terminated.

10. The electrical installation according to claim 9, wherein at least one of said feeders comprises at least one current sensor adapted for measuring an outgoing current and a difference in potential.

11. The electrical installation according to claim 9, wherein the data processor is configured to detect a frequency of an electrical signal supplied by an electrical grid to which said installation is connected.

12. The electrical installation according to claim 9, further comprising at least one home sensor measuring an environmental condition of the installation.

13. The electrical installation according to claim 9, wherein at least one of said devices is a heat exchanger and comprises a communication interface for communicating data concerning the temperature reached by the device.

14. The electrical installation according to claim 9, wherein said feeder is an electrical socket.

15. The electrical installation according to claim 9, wherein said feeder is an electrical panel.

16. The electrical installation according to claim 9, wherein said feeder is an electrical hub.
