Definitions
- the invention relates to energy optimization, and more specifically to a technique for managing the electrical power consumed by one or more connected home devices within a local communication network.
- a home has many domestic devices likely to consume significant electrical power, such as household appliances such as a dishwasher, a washing machine or a dryer. Such devices consume electricity irregularly in different phases of operation. Certain operating phases are thus highly consuming compared to others and lead to a peak in consumption. This phenomenon is amplified, when a user decides to operate several domestic devices at the same time, the power consumption of these is added. Such simultaneous operation of several energy-hungry devices then produces a peak consumption, potentially significant if the operating phases of the different machines in operation maximize the power consumed at the same time. Such a spike in consumption is often noted in the early evening, when an individual returning from work launches phases of operation of one or more household appliances in his home.
- a first existing solution to reduce such consumption peaks is to encourage the user of household devices not to exceed a maximum power consumption, as does the "Ecowatt” program in France. Similarly, the user may be encouraged to consume more during the days and times of the day with low overall consumption, if necessary through cheaper rates such as for example in the "off-peak hours” contracts. And EDF's "Tempo” in France. Nevertheless, if such a solution relies mainly on the goodwill of the user, its results are highly random and may require action on the part of the user.
- One of the aims of the invention is to remedy the shortcomings / disadvantages of the state of the art and / or to make improvements thereto.
- the invention relates to a method for managing the power consumption in a local communication network, comprising at least one device, the operation of said device having at least one operating phase.
- the method comprises the following steps implemented by a data processing unit:
- the information device relating to at least one operating phase of the device, the information relating to an operating phase comprising a power consumed by said device during this phase and an estimated duration of said phase;
- Consumption in the local network may have one or more levels of consumption, more or less high. These consumption levels depend on the use of devices in the local network.
- the operating phase for which information is sent by the device corresponds to a current or future operation phase.
- the device has real-time information that depends on both technical characteristics of the device, programming actions and / or interaction of a user on the device, local parameters measured by the device (for example, for a washing machine: weight of the laundry, temperature of the water or air, degree of dirt of the laundry ).
- Such a management method thus makes it possible to smooth the power consumption in a local network without requiring actions on the part of the user or to degrade the quality of the services provided by the device or devices of the local network.
- One or more levels of consumption can thus be compensated in the local network. It is thus possible to limit the consumption peaks that can occur on the network of an energy supplier.
- the reception of information relating to an operating phase of a device is implemented following a detection of an operating phase modification of the device.
- a modification of an operating phase corresponds, for example, to the start of a new operating phase or even to the user being able to pause an operating phase.
- the performances of the smoothing of the consumption are thus improved.
- the operating phase modification of the device is detected following receipt of a notification from the device.
- the device notifies the processing unit of any change in the operating phase, which thus makes it possible to adapt the level of discharge of the battery according to this modification.
- the reception of information relating to a phase of operation of the device is implemented repeatedly.
- the level of discharge required from the battery (s) present in the local network can thus be adapted.
- a step of charging the battery is implemented following the execution of the discharge command. This makes it possible to use periods during which the power consumption is low to recharge the battery or batteries and to smooth over time the power consumption in the local network.
- the battery (s) can be recharged from the utility's grid.
- the battery or batteries can also be associated with a renewable energy system, for example by means of solar panels or wind turbines. Such a battery charging is indeed of economic interest for the user of the local network.
- the compensated consumption stage is associated with the simultaneous use of a plurality of home devices of the local network. Use multiple devices simultaneously causes high consumption levels, which it is better to compensate.
- the steps of determining an output current to be delivered and sending a discharge command are performed for a plurality of consumption stages, until a complete discharge of the battery. This makes it possible to make the best use of the resources available in the local network and to smooth over time the power consumption in the local network.
- the method further comprises a step of identifying a consumption level to be compensated by comparison between two successive consumption levels.
- the invention relates to a processing unit, capable of being connected to a local communication network, said local network comprising at least one device, the operation of said device having at least one operating phase.
- This treatment unit comprises:
- a determination module arranged to determine a predicted power consumption in the local network for the duration of operation of said device in the form of at least one consumption stage and an associated duration of duration and, for a consumption level an output current to be delivered by said at least one battery to at least partially compensate said bearing;
- the invention relates to a gateway comprising a data processing unit according to the second aspect.
- the invention relates to a system for managing the electrical consumption in a local communication network, comprising at least one device, the operation of said device having at least one operating phase, at least one battery, arranged to receive a discharge command comprising an output current to be delivered and to execute said command, and a processing unit according to the second aspect.
- the invention relates to a program for a processing unit, comprising program code instructions for controlling the execution of the steps of the management method according to the first aspect, when this program is executed by the unit.
- processing device and a recording medium readable by a processing unit on which a program for a unit is recorded.

- FIG. 1 represents, in its environment, a system for managing electricity consumption within a local communication network 3.
- local communication network is meant a LAN type network ("Local Access Network”).
- This network can be in particular a home network or a corporate network.
- An access gateway 30 allows devices of the local network 3 to access an extended communication network 1 or WAN (for "Wide Area Network"), such as the Internet.
- the local network can be both a wired Ethernet network, according to the IEEE 802.3 standard, a wireless network type Wi-Fi, according to the IEEE 802.11, or 3G or a combination of both.
- the link can be direct, or use an intermediate device such as CPL boxes.
- the gateway 30 of the local network 3 is by definition the heart of a local communication network.
- the devices of the local network may be a set-top box, a mobile terminal, such as a smartphone or tablet. In the context of a home automation network, it is also devices or equipment of household appliances, alarm systems, sensors.
- the devices of the local network can receive data from other devices of the local area network or devices connected to the extended communication network and send data to a network device. local or connected to the extended communication network.
- the next step is the management of electricity consumption in the local network.
- FIG. 1 In Figure 1 are shown home devices 31-33.
- these household devices are household appliances such as a refrigerator 31, a dishwasher 32, a dryer, a washing machine 33, a freezer, etc. No limitation is attached to the type of these household devices. It can be any device on the local network that has a wired or wireless network connection.
- the dishwasher 32 has a first wash phase, a pause phase, a second wash phase and a drying phase.
- the washing machine 33 has a washing phase and a spin phase.
- each operating phase of a device of the local network may be associated a power consumed, such as the maximum power consumed, by this device during this phase.
- a power consumed such as the maximum power consumed
- each phase may be associated the average power consumed by this device.
- At each operating phase of a device can also be associated a duration of the phase.
- the dishwasher 32 may have a first phase of operation corresponding to a first wash of a duration of 25 minutes with a power consumption of 1400 Watts, a second phase of operation a duration of 20 minutes with a power consumption of 50 Watts corresponding to a pause phase, a third phase of operation corresponding to a second wash phase a duration of 30 minutes with a power consumption of 1600 Watts and a fourth phase of operation corresponding to a drying phase of a duration of 5 minutes with a power consumption of 50 Watts.
- the washing machine 33 may have a first phase of operation corresponding to a washing phase of a duration of 25 minutes with a power consumption of 400 Watts and a second phase operating mode corresponding to a spinning phase lasting 30 minutes with a power consumption of 1000 Watts.
- a battery 34 able to discharge on command of a control device, is also connected to the local area network 3.
- the battery 34 is also able to load on command of a control device.
- the battery 34 can be recharged from the energy provider's network.
- the battery 34 can also be associated with a renewable energy system, for example by means of solar panels or wind turbines. Such charging of the battery is indeed of economic interest for the user of the local network.
- the local network represented in FIG. 1 corresponds to an exemplary embodiment. No limitation is attached to the number of devices, batteries, or their type.
- the system also comprises a data processing unit 300, not shown in FIG. 1, capable of being connected to the local area network 3 and configured to manage the power consumption in the local area network 3.
- the data processing unit can be integrated in a dedicated device, or in one of the devices of the local network 3, in particular in the gateway 30 of the network.
- the access gateway 30, because of its central role in the local network, can in particular control the execution of the method, playing the role of the battery control device 34. Indeed, all the devices of the local network 3 are connected to it and by its routing function, it communicates with these devices.
- the access gateway 30 controls the local network 3, and therefore naturally has a coordinator position.
- processing unit 300 is integrated with the digital TV decoder.
- the data processing unit 300 is integrated with a device external to the local network, such as a device of a service provider, for example a device of the electricity supplier of the user. of the local network.
- a device external to the local network such as a device of a service provider, for example a device of the electricity supplier of the user. of the local network.
- the data processing unit 300 first obtains information relating to one or more operating phases of the devices of the local network. It is emphasized here that the management method can be implemented for one or more devices of the local network. It is not necessary for all the devices of the local network to provide information relating to their operating phases. The management method can indeed make it possible to smooth the power consumption for a single device.
- These devices are operated by the user and their operation will go through one or more phases each potentially having a different power consumption.
- the information obtained by the processing unit and relating to an operating phase for one of these devices includes in particular a predicted consumption by the device during this phase.
- the forecast consumption corresponds to a power consumed during this phase.
- the processing unit 300 determines an output current to be delivered by the battery 34 to compensate for all or part of the power consumed by one or more devices during a time interval from the acquired information.
- This time interval corresponds to the duration of an operating phase for a single device or to a part of an operating phase of a device when several devices are in use.
- different phases are observed, corresponding to consumption levels, for which it is possible to determine the expected power consumption and the associated dwell time. Only consumption levels at the local network level having a high value relative to other levels are thus compensated. These levels correspond to consumption peaks in the local network.
- a consumption stage to be compensated can be identified iteratively by comparison between two successive consumption levels.
- Consumption peaks may also correspond to consumption levels whose power consumption is greater than a threshold value. It is understood that there are many methods for identifying levels of consumption to compensate without the need to identify them here exhaustively.
- the processing unit 300 then sends the battery an output current discharge control determined for the duration corresponding to the consumption stage, to compensate for all or part of the selected consumption level.
- the processing unit sends a charge command to the battery 34.
- the power consumption in the local network 3 is smoothed and certain consumption levels associated with high power values (or consumption peaks) are compensated.
- a first consumption level of 25 minutes with a consumed power of 1800 Watts is observed.
- second consumption stage with a duration of 20 minutes with a power consumption of 1050 Watts
- third consumption level with a duration of 10 minutes with a power consumption of 2600 Watts
- fourth consumption stage with a duration of 20 minutes with a power consumption of 1600 Watts
- fifth consumption level of a duration of 5 minutes with a power consumption of 50 Watts.
- the processing unit determines for example that the consumption is high during the third consumption stage and commands the battery to contribute to the power supply of the local network by discharging.
- the processing unit can also smooth the consumption during the first consumption stage. Various embodiments are thus possible in order to smooth all or part of the consumption levels in the local network.
- the management method runs autonomously. No action is required for the user. For example, the user does not have to decide to turn on his dishwasher. The user must not also define a list of priority devices.
- the devices of the local network are not modified because of the implementation of the management method. No power off of a device is performed. The efficiency of these devices is thus optimum.
- the battery is recharged during periods for which the power consumption in the local network is lower. When the battery is associated with a renewable energy system, its charging is done transparently for the electricity supplier. No change in power consumption is thus made during periods corresponding to low consumption in the local network.
- the exchanges between the processing unit 300 and the devices 31-34 of the local network 3 are in accordance with the UPnP network protocol, for "Universal Plug and Play", promulgated by the UPnP forum. .
- the purpose of UPnP is to enable devices to easily connect and communicate within such a network. It is a set of communication protocols based on the IP (Internet Protocol, basic protocol for Internet type networks). To control network devices, the UPnP protocol uses control points. The processing unit then acts as a UPnP checkpoint and interacts with local network devices through UPnP services and actions provided by them.
- a checkpoint emits classically to the various devices of the local network of the so-called discovery messages in order to obtain in return a description of the devices corresponding to the request. These discovery messages are most often issued in point-to-multipoint communication mode, also called multicast, from the control point to the devices.
- a device compatible with the UPnP standard responds to these request messages, and additionally transmits, at regular frequency, presence messages to signify that it is active and connected on the network.
- the devices 31-33 implement a UPnP service, hereinafter called “Appliance”, to share with the processing unit information relating to their operating phases.
- This service includes the following three actions:
- the battery 34 implements a UPnP service, hereinafter called “Battery”, comprising the following actions:
- the "Battery” service also includes a StartCharge action to start the charging of the battery (and thus to stop its discharge).
- a discovery step E1 the processing unit 300 implements a discovery process of the home devices 31-33 connected to the local network and battery (s) available (s) in the local network.
- the processing unit 300 can receive messages sent by each home device and by each battery when connected to the LAN, for example when they are powered up, or for a home device, when launching a phase of operation by a user.
- a message may include a URL address to access an XML file including data static to give a description of the domestic device.
- the messages exchanged between the processing unit 300 and the home devices 31-33 are in accordance with the UPnP protocol. These different devices implement the "Appliance” service described above.
- the messages exchanged between the processing unit 300 and the battery 34 are in accordance with the UPnP protocol.
- the processing unit and the battery implement the "Battery" service described above.
- the SSDP protocol makes it possible to discover services offered on a network, such as the "Appliance” service and the "Battery” service.
- the SSDP protocol is defined by the IETF in a draft-cai-ssdp-vl-03.txt "Simple Service Discovery Protocol / 1.0 Operating without an Arbiter" of October 1999.
- These messages may be “alive” SSDP messages sent to a multicast address by the home devices for the "Appliance” service and by the battery 34 for the "Battery” service.

- NT urn: schemas-upnp-org: service: battery: l
- NTS ssdp: alive
- the processing unit 300 can itself initiate a discovery process of domestic devices offering the service "Appliance". It is the same for the service "Battery". Such a process can be initiated when connecting the processing unit to the network to detect devices that would already be connected to it, especially in the case where the devices remain connected to the network permanently when powered.
- the processing unit then sends a request message on the network, for example of the "M-SEARCH request” type.
- the devices offering these services identify themselves to the processing unit by transmitting notification messages as described above.
- a step E2 the processing unit is waiting for a timer to expire (main loop). This delay is for example of the order of five seconds.
- a detection step E3 the processing unit determines whether a new device has been detected. More specifically, the processing unit determines whether it has received an "alive" SSDP message.
- the processing unit obtains static data provided by the newly discovered home device 31-33 or battery 34.
- the processing unit can access this data in the form of an HTML file by means of the URL address included in the message transmitted by the home device or the battery.
- This static data gives a description of a device and may include a serial number, the manufacturer's name, the device model, a device type, a software version etc. This allows the processing unit to maintain an inventory of devices connected to the local network and likely to consume energy.
- a recording step E5 the processing unit can send to each new domestic device 31-33 discovered a subscription message so that in the future this device notifies the processing unit 300 the events such as starting, pausing, or ending an operating phase.
- the start, the pause or the end of a phase are indeed particular moments during which the consumed power may change and following which the device concerned can update its estimate of the durations and consumption cycles to come.
- the knowledge of these events by the processing unit is therefore necessary for it to maintain its consumption forecasts and to try to smooth consumption as much as possible.
- Such a subscription message may contain a URL response address to which the home device must send its notification messages to warn the processing unit of the occurrence of an event.
- steps E1 to E5 allow the processing unit to be aware of the devices connected to the network. With regard to the domestic devices 31-33, the processing unit requires to be warned of the operating phase changes of these devices. The processing unit then implements step E2 (main loop). When in step E3, no new device has been detected, during an event detection step E6, the processing unit 300 determines that an operation phase change has occurred, c. that is, a new operating phase has started on a home device or the user has paused one of the operation phases. The processing unit 300 can make this determination on receipt of a notification message sent by the home device itself.
- HOST delivery host: delivery port
- CONTENT-TYPE text / xml
- NTS upnp: propchange
- the processing unit receives this notification message following the subscription made in step E5 or following a query through the GetCurrentCyclelnfo action of the "Appliance" service.
- the processing unit obtains information relating to one or more operating phases of a domestic device after starting a new operating phase thereon. or pausing an operating phase, such start or pause being determined by the processing unit in step E6.
- the processing unit interrogates a home device for which it has determined the start of a new phase of operation or a pause by the user during the step E6 and obtains or receives the information requested from the device.
- the domestic device 31-33 can indicate the power consumed during this phase and an estimated duration of this phase.
- such a query can be performed through the action GetListOfCycle service "Appliance" described above. This allows the processing unit to have the necessary information for estimating the level or levels of consumption and their possible smoothing.
- a step E8 the processing unit determines whether a battery 34 is available. If this is not the case, the processing unit then implements step E2. In the opposite case, that is to say if at least one battery 34 is available, the processing unit determines in a step E9 a program for using the electric charge of the battery or batteries to compensate for one or more consumption levels in the local network.
- This usage program includes in particular a battery identification, an output current to be delivered, a discharge start time and a discharge duration.
- This utilization program is determined taking into account the device or devices in operation, their respective operating phases and the power consumed during these operating phases. Thus, the utilization program is determined according to a predicted power consumption in the local network for the duration of operation of the device or devices in the form of consumption stage and an associated bearing time.
- a step E10 the processing unit detects according to the usage program whether the start of discharge is immediate.
- a step El i the processing unit sends a discharge command to the battery identified by means of a DeliverCharge action of the "Battery" service described above.
- the processing unit schedules the discharge command at the start of discharge time. .
- step E2 the processing unit then implements step E2.
- step E6 When, in step E6, there has been no detection of a new phase of operation or of pause, the processing unit obtains during a step E13 for one or more household devices a consumption instant, information on the status of the current operating phase of it and the time remaining to complete the current phase. This data is obtained through the GetPowerConsumption and GetListOfCycles actions of the "Appliance" service described above. Still in this step E13, the processing unit obtains a current electrical charge of the battery 34. This data is obtained by means of a GetCurrentChargelnfo action of the "Battery" service.
- This obtaining or repeated reception over time allows the processing unit to update the previously acquired information relating to the operating phases of a device of the local network. This can indeed update during an operating phase its estimate of the duration of this phase and the power consumption during this phase. For example, during a washing phase of a washing machine, the cold water whose temperature may vary from one washing phase to another must first be heated and the duration as well as the estimated power consumption for this washing phase can be updated by the washing-machine once the water temperature required for washing reached. The battery usage program can then be updated based on this new information. Such a repeated obtaining may also allow the processing unit to draw histograms for monitoring the consumption of each domestic device. These histograms can then be displayed for the user. The processing unit then implements step E2.
- the presence in the local network of at least one battery thus makes it possible to absorb consumption peaks produced by one or more domestic devices.
- the processing unit can then smooth the power consumption in the local network.
- step E9 An implementation of step E9, during which a program for using the electric charge of the battery or batteries is determined, will now be described in relation to FIG. 6.
- a utilization program notably comprises a identification of a battery, an output current to be delivered, a start of discharge time and a discharge duration. It is emphasized here that this is only an example of the implementation of this step E9 and that many other possibilities exist without being described in an exhaustive manner.
- the processing unit determines from the information relating to operating phases of one or more home devices, obtained during the step of obtaining phase information E7, a predicted power consumption. More precisely, the processing unit determines, as a function of the domestic devices in use, successive consumption levels and associated dwell times. Among all the consumption levels, the processing unit can then select one or more bearings to compensate. As an illustrative example, the processing unit selects a number N of consumption levels for which the power consumed is maximum. Still as an illustrative example, the processing unit selects one or more consumption levels whose consumed power exceeds a threshold value. The current consumption level corresponds to the first consumption level selected.
- the processing unit determines an electric charge value available in the local network, that is to say by means of the battery or batteries 34, from the information obtained in step E13 and the where appropriate, scheduled discharges to handle previous consumption levels.
- the processing unit determines which power W is needed and for what duration.
- the power W corresponds for example to the power of a consumption stage. It can also be the difference between the power required for the level of current consumption and that required for a next consumption level. It can also be the difference between the power of the bearing and a threshold value of power.
- step E94 the processing unit checks whether the available electrical load in the UPnP battery (s) is sufficient. If this is not the case, in a step E95, the processing unit determines a program for using the UPnP battery (s). This usage program corresponds to a discharge of the UPnP battery (s) at the level of the available electrical charge. The local network no longer has energy resources, step E9 ends.
- the processing unit determines a program for using the UPnP battery (s).
- This usage program corresponds to a discharge of the UPnP battery (s) up to an output current and for the duration of the consumption stage.
- Step E97 if there are still consumption levels to be treated, the next consumption level becomes the current consumption level and the electric charge available in the UPnP battery (s) is updated to take into account the programmed discharge. Step E92 is again implemented.
- Step E9 is completed when the set of consumption levels to be compensated has been processed.
- step E4 the access gateway 30 obtains the static data of the washing machine 33.
- the access gateway 30 sends a subscription message to the washing machine so that the it notifies him of the events concerning him, for example, when the Fabrice user starts, pauses or stops his washing machine.
- Fabrice also has UPnP batteries that are recharged by solar / wind energy or by the sector. Fabrice decides to start his washing machine.
- the washing machine is the only active domestic device in the local network. The washing machine starts normally for a 55-minute program. It is assumed that no consumption smoothing is implemented when only one device is in operation. Fabrice then starts his dishwasher 32. Two domestic devices are thus active in the local network.
- the access gateway 30 detects that a consumption stage will occur with a consumption of 2600 Watts for 10 minutes as shown in Figure 2c. This level of consumption represents an intensity of 11.8 amperes.
- the access gateway identifies in step E8 that the battery 34 is available with a load of 1800 mAh. This battery 34 can thus provide a discharge current of 10.8 amperes for 10 minutes.
- the access gateway 30 decides to discharge the battery 34 with an output current of 10.8 amperes at the highest consumption plateau, in order to compensate the latter.
- the power consumption in the local network is shown in Figure 3a.
- the first level of consumption of a duration of 25 minutes with a power consumption of 1800 Watts the second consumption stage of a duration of 20 minutes with a power consumption of 1050 Watts, the third consumption level of a duration of 10 minutes with a power consumption of 200 Watts, the fourth consumption stage with a duration of 20 minutes with a power consumption of 1600 Watts and the fifth consumption stage with a duration of 5 minutes with a power consumption of 50 watts.
- the highest consumption level in the local network following the execution of the discharge control is thus 1800 watts for 25 minutes. As a result of this command, the battery 34 is completely discharged.
- the highest consumption level was reduced by 800 Watts, that is to say by 30 percent without any user configuration: the user did not have to specify a delayed start, a threshold or a list of priority devices. Domestic devices were not stopped abruptly by power off.
- the access gateway 30 is notified and can immediately adapt or modify the discharge of the battery.
- the access gateway 30 determines the power associated with the previous consumption stage (1800 Watts) and seeks only to absorb the difference between the two consumption levels.
- the access gateway detects that the first stage is at 1800 Watts and the second stage is at 2600 Watts, it commands the battery to inject an output current of 3.7 amps. for 10 minutes to absorb only 800W.
- the charge of the battery is 1183 mAh.
- the first level of consumption is observed for a period of 25 minutes with a power consumption of 1800 Watts, the second consumption stage of 20 minutes with a power consumption of 1000 Watts, the third consumption level of a duration of 10 minutes with a power consumption of 1800 Watts, the fourth consumption stage with a duration of 20 minutes with a power consumption of 1600 Watts and the fifth consumption level with a duration of 5 minutes with a power consumption of 50 Watts. In this way, the consumption is reduced to 1800W for 10 minutes at the third consumption level.
- the access gateway can also decide to smooth the consumption to a value of 1600 Watts corresponding to the value of the next consumption stage.
- the first level of consumption lasting 25 minutes with a power consumption of 1600 Watts
- the second level of consumption of a duration of 20 minutes with a power consumption of 1000 Watts
- the third and fourth levels of consumption of a duration of 30 minutes with a power consumption of 1600 Watts
- the fifth consumption level with a duration of 5 minutes with a power consumption of 50 Watts.
- the battery 34 then discharges during the first and third consumption levels of 200 additional watts, or 35 minutes, which corresponds to a discharge current of 0.91 amps for 35 minutes. Following this discharge, there is 652 mAh remaining in the battery. In this example, the highest consumption level after performing the discharge commands is 1600 Watts for 55 minutes.
- the access gateway may also decide to smooth the power consumption to a value corresponding to a complete discharge of the battery 34.
- the consumption can be reduced to a value of 1468. watts.
- the first level of consumption of a duration of 25 minutes with a power consumption of 1468 Watts the second consumption stage of a duration of 20 minutes with a power consumption of 1000 Watts, the third and fourth levels of consumption with a duration of 30 minutes with a power consumption of 1468 Watts and the fifth consumption stage with a duration of 5 minutes with a power consumption of 50 Watts.
- the energy supplier can define a consumption threshold that must not be exceeded. It is then possible to trigger the implementation of the management method when the power of certain consumption levels is close to this threshold, for example of the order of 75 percent of the threshold value.
- the energy provider can define full hours and off-peak hours. It is then possible to trigger the implementation of the management method only during peak hours.
