Definitions
- the present invention generally relates to the field of energy routing management in an electrical distribution network.
- the electricity distribution network currently, whether in a neighborhood or inside a building, transmits alternative energy (AC) whose origin and destination is not perfectly traceable today. hui. It is therefore not possible to certify that a customer who buys "green” energy (from the photovoltaic, wind, or other renewable energy sector), at a time T, actually consumes this energy.
- AC alternative energy
- thermal regulation of 2020 in France, requires in new housing to have a tool for local energy production as well as a storage medium, both using continuous electrical energy (DC) , to be able to tend towards a house autonomous in energy.
- DC continuous electrical energy
- the electrical architecture for the production, distribution and use of energy in the home must also take into account the multiple losses of energy conversion, be able to provide both AC power for the existing equipment, in direct current for new equipment or to use it directly, to provide its energy security according to its priorities, its characteristics, availability and traceability of energy at lower cost.
- Ordinance No. 2016-1019 of 27 July 2016 on collective shared consumption of electricity should require the establishment of tools such as, for example, a platform for the exchange of electricity. energy at the mesh of a neighborhood and / or a low voltage substation (LV) and / or an electrical outlet of a substation BT.
- LV low voltage substation
- the present invention improves this situation.
- the flow further comprises, for an identification of the delivery via the network, a complementary part including identification data of the delivery, complementary part in which the electrical power is amplitude modulated, the complementary part thus presenting durations during which the electric power is lower than said constant level of the main part of the flow.
- electrical power modulation is to be considered in the general sense and may encompass both direct power modulation, but also possibly a voltage modulation (whose effect, DC DC, may return to modulate the power ).
- the term "via an electrical distribution network” is understood above to mean the borrowing of a local subnetwork of the general electrical distribution network, such as, for example, the low voltage network typically.
- the quantity of energy being delivered in direct current comprises durations during which an electric voltage of the flux is zero, the modulation being applied to the voltage to code the identification data of the delivery on two binary values corresponding to a zero voltage and a maximum voltage, said maximum voltage corresponding to said constant power level of said main part of the flow.
- the delivery of energy is effected by transmission of a plurality of successive packets of time streams each comprising a main part of flows and a complementary part including identification data of the delivery, the complementary part of flows. of each packet preceding the main part of the stream.
- the implementation of the invention can be manifested in the case of the delivery of a single packet thus comprising a single stream, if this single packet is sufficient to provide the amount of electrical energy required.
- these packets may be temporally spaced by a chosen duration of synchronization of the distribution network, during which the power is zero. This synchronization time may allow entities receiving the packet start reading the -tête in packets (the aforementioned complementary portion) to extract the data encoded therein.
- the identification data may comprise for example at least:
- the identification data may further include:
- a timestamp can be provided from among these data to temporally stamp the delivery of the stream, or simply the reception of these data can be provided by a computing device which then applies this time stamp in addition to these data received for a delivery date certification.
- the identification data may furthermore comprise in each current packet:
- This embodiment thus makes it possible to identify the packets relating to the same delivery and their order to await the reception of any additional packets.
- the method may then comprise the steps implemented by a computing device connected to the producing entity:
- It may be a "smart" router of the type described in WO-2014/147437.
- the aforementioned computing device can be integrated into the router, or directly connected to the energy meter, of the producing entity.
- the method may also comprise at least the steps implemented by the consuming entity:
- the method may also include at least one subsequent step implemented by the consumer entity:
- the computing device of the consuming entity at the end of receiving the stream from the producing entity, implementing the computing device of the consuming entity to check a conformity between a quantity of energy accumulated in the aforementioned energy storage means and the quantity of energy to be delivered, indicated in the data of the complementary part of the flow.
- the present invention also provides a system for implementing the above method, comprising an electric power generating entity and an electric power consuming entity, and further comprising at least:
- a first computing device for applying a modulation to the complementary part of the stream encoding the delivery identification data
- a second computing device for verifying the delivery identification data in said complementary part of the stream and storing said data in memory.
- the present invention also aims in isolation the first device of such a system, being then configured to apply a modulation to the complementary part of the stream encoding the delivery identification data.
- the present invention also aims in isolation the second device of such a system, being then configured to check the delivery identification data in said complementary part of the flow and store said data in memory.
- the present invention also relates to a computer program comprising instructions for implementing the above method, when this program is executed by a processor.
- Figure 2 described below may be an example of a flow chart of a general algorithm of such a computer program.
- the invention makes it possible to have a new DC distribution architecture capable of routing and tracing the origin of energy packets by implementing a simple data transmission protocol and not requiring no additional means other than a simple computer tool. More particularly, this computer tool is judiciously programmed using a computer program to apply the above modulation and thus incorporate the data of the source of this energy, directly in the energy flow supplied to the consumer entity.
- the invention thus finds an advantageous but nonlimiting application in the context for example of a supply of energy on demand peer-to-peer, with a possibility of tracing the source of this energy.
- a local producer can provide energy to a consumer who wants to consume locally and this tool allows him to trace this exchange.
- the invention thus proposes to reconsider both the notion of energy distribution, the marking of the source of the current for its traceability, and that of the routing of these energy flows within a neighborhood, d. a low-voltage station or an artery, to facilitate peer-to-peer exchanges between energy producing entities on the one hand and consuming entities on the other hand, at a given instant, at attractive cost, in order to to respond in particular to the aforementioned draft Ministerial Ordinance on "shared self-consumption".
- FIG. 1 is a general diagram of a system for implementing the invention
- FIG. 2 illustrates the general steps of a process within the meaning of the invention
- FIG. 3 illustrates a first device in the sense of the invention and the successive packets shaped by such a first device, for transmission via the electrical distribution network, from a producing entity
- FIG. 4 illustrates a second device in the sense of the invention and the processing of the packets received by such a second device, with a view to storing the energy received in an energy storage means, in this case an inverter, of a consumer entity, and
- an energy storage means in this case an inverter, of a consumer entity
- FIG. 5 illustrates successive packets transmitted via the electrical distribution network, in a particular embodiment.
- an EPI producing entity produces an electrical energy, here by photovoltaic PV effect according to a renewable energy production.
- the production surplus of this EPI entity (relative to a local consumption) can be stored in an energy storage means, such as a battery or a UPS, for subsequent transfer of this surplus energy.
- an EC1 consuming entity for example a third-party electric vehicle charging
- EC2 for example for the electricity consumption needs of another third party.
- another producing entity EP2 to produce electrical energy, of EL wind origin, and the production surplus can be stored in energy storage means such as a battery or an OND of this other producing entity.
- EP2 with a view to possibly supplying other third party consumers EC1.
- a transaction platform PF through which the different consuming entities EC1, EC2, can solicit given amounts of energy, with for example a wish as to the nature of the production of these quantities of energy (renewable or other energies, by example, or energy from neighboring local production or not, for example).
- the platform PF may be connected by power line or other means (such as an Internet communication via a cellular network or the switched network) to DIS computer devices with each EPI, EP2, EC1, EC2 entity. , to organize each transaction and in particular:
- the quantity of energy is delivered by the producing entity, it is transferred via the network, using respective ROU routers of the producing entity and the consuming entity that define inputs of the RES network. These may typically be routers as described in WO-2014/147437.
- the producing entity EP retrieves in step S2 of the data related to the transaction and typically corresponding to:
- the computing device DIS of the producing entity EP then generates a code corresponding to these data, with a view to applying this code in the form of a modulation of the time flow of power as described below.
- the producing entity delivers the requested amount of energy in the form of a time flow of electrical power (which may correspond more precisely to a succession of PI packets, P2 as will be seen more 3 to 5), with, in this stream, a portion which is modulated in amplitude according to the code corresponding to the above data.
- the time flow of the packet PI does indeed comprise a first part in which, here, the voltage v (in direct current DC) hangs from successive values "0" or "1", which makes it possible to encode in binary the aforementioned data.
- the packet PI comprises a succession of maximum voltage values (at "1") which correspond to the quantity of energy required (or only a part of the energy required if the latter is distributed over several successive packets).
- this time stream is transmitted via the network RES by the router ROU of the producing entity. It transits, from router to router, in the network according to a point-to-point mode in the example described, and more particularly each router that does not recognize the identifier of the entity with which it is associated (KO arrow at the output of the S4 test) ignores this stream and transmits it to a neighbor router (step S5).
- the ROU router of the consuming entity which is declared in the encoded data at the beginning of the flow recognizes in these data the identifier of the consuming entity to which it is directly connected (OK arrow at the exit of the test S4).
- This router ROU then transfers this time flow to energy storage means such as the battery or the inverter to which it is connected (as illustrated in FIG. 1), with a view to storing energy in this means of storage.
- storage in step S7 and parallel the computer device DIS connected to this router ROU stores in memory the data presented in this stream in step S6.
- the computing device DIS of the consuming entity can check (step S8), at the end of the reception of all the stream or all the packets of the stream that the quantity of energy received and stored for example in the OND inverter corresponds to the amount of energy announced in the data encoded in the stream and, the if necessary, send in step S9 a message to the platform, compliance of the energy delivery compared to the previously initiated transaction.
- the process can continue by the organization by the platform of a billing of the producing entity to the consumer entity.
- the computing device DIS of the consuming entity can be programmed to transmit to the platform PF the quantity of energy actually received from the producing entity, for purposes of less than expected billing.
- FIGS. 3 to 5 an example of a temporal flow form corresponding to the electrical energy supplied to a consuming entity and including in particular (as a stamp) identification data of this energy (with respect to FIG. producing entity, the consuming entity, the type of production, etc.).
- the data that can be encoded in the stream are:
- a current packet number NUM from among these consecutive packets (for example the fifth packet over thirteen packets in all).
- the current is continuous (DC mode) and the voltage is at low voltage, for example 48 volts or more, as detailed below.
- the voltage can be modulated (simply by means of a switch function) by applying the binary values "0" or "1" corresponding to respective levels of zero voltage, or maximum at 48 V for example.
- the computing device DIS associated with the producing entity EP operates this modulation to code this data binary in the voltage v, to deliver a corresponding power, thus modulated and therefore in the network via the router ROU of the producing entity.
- the computing device DIS comprises a communication interface COM with the router ROU, as well as a processor for applying the coding and a memory MEM storing instructions of a computer program within the meaning of the invention.
- the processor cooperating with the memory MEM, executes these instructions in order to apply the aforementioned coding.
- the device DIS applies a synchronization time Ts (specific to the network) between the successive packets PI, P2.
- a network control entity may define an instantiation of the packets transmitted by each producing entity (as a "scheduler" in the telecommunications field).
- This may be, for example, the PF platform which defines, after each transaction, the start times of each energy packet requested via the network.
- the platform can define the duration of the synchronization Ts between two packets P1, P2 sent by the entity EP.
- each DIS device refers to the same network clock to transmit its packets.
- it can be simply programmed packet transmission times for each producing entity (for example at times assigned to each entity and fixed in a day).
- a computing device DIS of a consuming entity on receipt of the succession of these packets PI, P2.
- a computing device DIS comprises a communication interface COM with the network (via the ROU router of its entity).
- This communication interface COM cooperates with a processor PROC which can read the instructions of a computer program within the meaning of the invention, stored in a MEM memory of the device.
- this device DIS can implement the step S4 of reading the data in header of the packets, ignore these packets and simply transmit them to a next router if they are not intended for the EC entity to which it is associated (step S5), or otherwise store the data in the header of the packets (step S6) in a memory which may be the same as the aforementioned memory MEM (or a different memory), then control the router for that it switches the energy received in the packets to the OND of the consuming entity EC (step S7).
- the form that can be had by the packet header modulation for the binary coding of the data is described.
- Successive binary values can be observed at "0" or "1" (maximum voltage).
- the duration TO during which the voltage value is at "0" for a bit is preferably of the order of one to a few milliseconds.
- these TO times are therefore as short as possible in order to reduce as much as possible the times during which no energy is transmitted.
- the times T1 during which the voltage is maximum may be greater than the order of milliseconds (and thus T1> T0) to transmit as much energy as possible in a packet.
- Rou routers energy flow (of the type described in WO2014147437), located in tertiary premises and / or homes and / or a vehicle charging station and / or within a HTA / LV substation (for "high / low voltage"), each having at least one or more networks DC power distribution system (of a voltage level adapted according to the topologies and uses).
- These energy flow routers can then assume the same routing role as a router in data transmission networks by assuring and tracing the transmission of energy packets from point A to point B.
- Such an architecture makes it possible to implement the transmission of electrical energy in packets, such as successive frames of data.
- ROU energy routers can directly integrate the aforementioned computing devices DIS, so that they have an artificial intelligence ROU that can be characterized by a multi-agent system (SMA).
- SMA agent is then an at least partially autonomous entity comprising:
- the PF platform itself, has an artificial intelligence that allows, on request, to research and predict, the quantities of energy to buy or sell on a grid at the best price depending on the types of energy and energy. moments of the day.
- the PF platform therefore presents itself as a transaction agent that links the electrical equipment wishing to consume with the energy source, and counts the energy exchanges for a billing agent for energy units hereinafter referred to as "WattCoins".
- WattCoins A forecasting and realizing agent can be provided in connection with the platform to enrich forecasts and knowledge with SMA agents.
- a smart router with an agent for analyzing and developing DC energy packets, in homes, charging stations and an HTA / LV substation makes it possible to transform the AC electrical energy and / or DC in DC energy packets, to transmit to a consumer or to receive these packets from a producer in order to transform them into AC and / or DC electrical energy.
- An advantage of this implementation is that it allows the development of new services such as energy on demand, green energy, provenance, etc. Indeed, the transmission of energy can be carried out continuously (AC and / or DC), in which an amplitude modulation is applied to code in binary data to be transmitted.
- DC DC can be generated a square signal as shown in Figures 3 to 5 (or any other form of course), but at a high sampling rate (period of the order of one millisecond) which s' Apparent to energy chopping, for any voltage level (low voltage at 48 V or voltages like 400 or 1500 V).
- a digital encryption key can be provided to develop a digital certificate encoded in the header of the packets taking into account, as an example for France, an electric delivery point identifier of the housing, the tertiary, the charging station of the distribution network. It is the digital signature of the place of production or consumption.
- PRM Measurement Network Point
- a device DIS ensuring the analysis and development of DC energy packets is able to develop a feed frame, depending on the negotiations operated for a duration such as a day by the platform of exchange of energy in the neighborhood (thus connected to an intelligent agent acting as a "trader").
- the device DIS can cooperate with a voltage generator DC of magnitude v (which for example may be 48, 400, 1500 V) at the input, to output a conventional data frame type "Ethernet or other", but particularly here in the form of a feed frame for a neighborhood consumer, also having a DIS reading device.
- Each energy packet is separated by time synchronization information Ts.
- Each receiving device DIS following the detection of this synchronization reads the header of the new packet that passes, to determine whether or not recipient. If it is a recipient, it can drive the storage of energy, and if it is not, it waits for the next synchronization.
- the transmitted frame has two distinct parts, the header (identification bytes) and the body (the energy packet itself). The entire constituted frame is converted into energy.
- the logical "1" of a duration T1 correspond to the voltage level transmitted (for example, can be 48, 400, 1500 V) and the logical "0" of a duration T0, correspond to the voltage zero: T0 being less than or equal to T1.
- durations T0, T1 on one side and the synchronization period Ts on the other There is no specific relationship between the durations T0, T1 on one side and the synchronization period Ts on the other.
- the durations may be equivalent or different, or even not at all if the synchronization information was for example a frequency or a puls with a characteristic shape in voltage, frequency and duration.
- the agent for analyzing and generating DC energy packets of the DIS device makes it possible to determine whether the packets received come from the producer with whom the consumer has made an offer to purchase via the platform, if the energy packets are good for him, how many packets he has to receive, whether the energy received is of renewable origin or not, local or not (so-called "green” or “red”).
- the set of energy frames are then stored in an inverter, a battery, an ultra capacitor, an electric vehicle, or other to be converted into energy (and this including the identification bytes to compensate for possible losses networks). Then, it is possible to destock this energy for the electrical uses concerned at the consumer.
- the PF collaborative platform for client / producer contacting collects at the level of a neighborhood or a low-voltage branch (or artery) of the network the needs and provisions of energy, current tariffs and possibly the virtual exchange currency "Wattcoins".
- a demand energy of a consuming entity can be addressed to the collaborative platform for a quantity Q, for and in a given time T, with the type of energy chosen.
- the platform selects a list of producers (in the neighborhood or upstream of the HTA / LV substation) that for this length of time are likely to provide this amount of energy, as well as the various rates offered.
- Energy can come from one or more producers depending on the quantity demanded, the differences in pricing, the type of energy, and the number of "Wattcoins" available to the consumer.
- the consumer device can make its request to the selected producer (s) of its request for a quantity Q of renewable energy or not, depending on the tariffs and the requested time.
- the device of the producer (s) generates energy packets that will be received by the consumer device.
- the number of energy packets received may be provided as notification to pay the number predicted "Wattcoins", via a billing agent connected to the platform for example (or in the form of a computer module stored in each DIS device).
- the sale makes it possible to obtain Wattcoins which in turn make it possible to buy energy, or time of electric use, or recharge an electric vehicle in the neighborhood.
- Such an embodiment allows the traced exchanges, even to peer energy, between producers and consumers on the same LV artery, in a private area to the mesh of a neighborhood, a low voltage substation (BT) or a leaving BT, or within a building, a habitat between two equipments, and guarantees the origin of the production of the electric current (green or non-green energy, local in the eco-neighborhood, or national, etc.).
- BT low voltage substation
- the energy flow routers can then assume the same routing role as a router in the data networks by assuring and tracing the transmission of energy packets from point A to point B, such as communications. in a telecommunications network.
