Abstract

A method for managing electricity use of a plurality of household appliances connected within a local communication network and having one or more operating phases. The method includes the following steps, implemented by a data processing module: acquiring information related to the operating phases, in progress or forthcoming, for at least two household appliances, the information related to an operating phase for a household appliance including the power used by the household appliance during the phase; determining, on the basis of the acquired information, at least one operating phase of one of the appliances to be interrupted so as to minimize peak power use; and interrupting the determined operating phase.

Claims

1. A method comprising:

managing power consumption of a plurality of domestic appliances connected within a local communications network, the operation of at least two domestic appliances having one or more operating phases, wherein managing comprises the following acts implemented by a data-processing module capable of being connected to the local communications network;

acquiring information relative to operating phases in progress or yet to come for at least two domestic appliances, the information relative to an operating phase for a domestic appliance comprising the power consumed by said domestic appliance during this phase and a maximum interruption duration of said phase,

determining as a function of the acquired information, at least one operating phase of one of said appliances to be interrupted so as to make a compromise between total maximum power consumed by said at least two domestic appliances, so-called consumption peak and offset over time of different programs, so as to minimise duration of the interruption of the operating phases of the domestic appliances,

interrupting said determined operating phase during an interruption duration less than or equal to the maximum interruption duration, and wherein the interruption duration is equal to a duration of the consumption peak when the maximum interruption duration is greater than or equal to the duration of the consumption peak.

2. The method according to claim 1, wherein the data-processing module acquires the information relative to operating phases in progress or yet to come of domestic appliances, after startup by one of said domestic appliances of a new operating phase or a pausing by a user of an operating phase.

3. The method according to claim 1, wherein the data-processing module repeatedly acquires the information relative to operating phases of domestic appliances.

4. The method according to claim 1, wherein said data-processing module interrupts said determined operating phase during an interruption duration equal to the maximum interruption duration when the maximum interruption duration is less than the duration of the consumption peak.

5. The method according to claim 1, wherein prior to the determination step of at least one operating phase to be interrupted, the data-processing module compares the amplitude of the consumption peak to a preset threshold.

6. The method according to claim 1, wherein the processing module programs the interruption of said operating phase at a later time.

7. An apparatus comprising:

a processor; and

a non-transitory computer-readable medium comprising code instructions, which when executed by the processor configure the processor to perform acts comprising;

a processor capable of being connected to a local communications network; and

a non-transitory computer-readable medium comprising code instructions, which when executed by the processor configure the processor to perform acts comprising;

acquiring information relative to operating phases in progress or yet to come for at least two domestic appliances connected within the local communications network and functioning according to several operating phases, said information relative to an operating phase for a domestic appliance comprising the power consumed by said domestic appliance during this phase and a maximum interruption duration of said phase,

determining, as a function of the acquired information, at least one operating phase of one of said appliances to be interrupted so as to make a compromise between the total maximum power consumed by said at least two domestic appliances, so-called consumption peak and offset over time of different programs, so as to minimise duration of the interruption of the operating phases of the domestic appliances, and

interrupting said determined operating phase during an interruption duration less than or equal to the maximum interruption duration, and wherein the interruption duration is equal to a duration of the consumption peak when the maximum interruption duration is greater than or equal to the duration of the consumption peak.

8. The apparatus of claim 7, further comprising a gateway comprising the processor.

9. The apparatus of claim 7, comprising a power consumption management system comprising a plurality of domestic appliances connected within the local communications network and a gateway comprising the processor.

10. A non-transitory computer-readable medium comprising instructions stored thereon for execution of a method for managing power consumption of a plurality of domestic appliances connected within a local communications network, when this program is executed by a processor connected to the local communications network, wherein the instructions configure the processor to perform acts comprising:

managing power consumption of the plurality of domestic appliances connected within the local communications network, the operation of at least two domestic appliances having one or more operating phases, wherein managing comprises;

acquisition of information relative to operating phases in progress or yet to come for at least two domestic appliances, the information relative to an operating phase for a domestic appliance comprising the power consumed by said domestic appliance during this phase and a maximum interruption duration of said phase,

determination as a function of the acquired information, of at least one operating phase of one of said appliances to be interrupted so as to make a compromise between the total maximum power consumed by said at least two domestic appliances, so-called consumption peak and offset over time of different programs, so as to minimise duration of the interruption of the operating phases of the domestic appliances, and

interruption of said determined operating phase during an interruption duration less than or equal to the maximum interruption duration, and wherein the interruption duration is equal to a duration of the consumption peak when the maximum interruption duration is greater than or equal to the duration of the consumption peak.
