[0034] The technical solution of the present disclosure is further described in detail below through the accompanying drawings and embodiments.

[0035] Schematic diagrams of some embodiments of the energy router disclosed in the present invention are as follows Figure 1 The energy router includes:

[0036] Multiple ports 101 are channels for energy routers to transmit energy to the outside, and can allow energy and PLC data to be input into or output from the energy router, or both. In some embodiments, the transmission of PLC data in the energy network uses the same link as the energy to be transmitted and interacted.

[0037] The energy transmission switch 102 can control the opening and closing state of the port. In some embodiments, the energy switch is controlled according to the inflow or outflow of energy, and the port on the transmission path of the current energy router is turned on, so as to control the flow of energy. In some embodiments, when energy transmission is determined, a PLC energy transmission instruction from other energy routers, control terminals or routing components is received. When the PLC energy transmission instruction is received, the energy transmission switch is turned on; when the PLC energy transmission completion instruction is received from other energy routers, control terminals or routing components, the energy transmission switch is turned off.

[0038] The routing component 103 can determine the energy transmission path according to the PLC data and the stored routing information. In some embodiments, the routing component 103 can determine the destination address according to the PLC data; determine the energy transmission path based on the shortest path algorithm according to the stored routing information, and then determine the next hop address. In some embodiments, the routing component turns on the energy transmission switch of the port according to the port associated with the energy transmission path, so that the power input to the energy router is output from the turned-on port.

[0039] Such an energy router can receive energy and PLC data, plan a transmission path for energy according to the PLC data, and open the ports on the transmission path for energy transmission, so that energy can be flexibly transmitted in the energy network, facilitate the transaction of electricity, and improve the flexibility of energy interaction.

[0040] In some embodiments, the routing component 103 may include an energy path storage unit and an energy path optimization unit. The energy path storage unit can store the shortest energy transmission path within the system network. When a new energy transmission path is created, it is directly stored in the energy path storage unit. When a new energy transmission path is added and the path is shorter, the energy path storage unit is updated. The energy path optimization unit selects the shortest energy transmission path from the energy path storage unit. Such an energy router not only improves the efficiency of path planning, but also continuously optimizes the transmission path and reduces the loss of energy during the transmission process.

[0041] In some embodiments, when the routing component 103 cannot generate a transmission path according to the stored routing information, it sends broadcast information to other routers through the port, and the energy router that receives the broadcast message feeds back the routing information associated with the destination address stored in itself, and determines the energy transmission path according to the updated routing information. The routing component 103 updates the stored routing information according to the received path feedback, and then determines the energy transmission path based on the shortest path algorithm according to the updated routing information, and then determines the next hop address and output port, and turns on the energy transmission switch of the port.

[0042] Such an energy router can obtain routing information from other network nodes by broadcasting information when its own network topology is incomplete, and then supplement its own stored network topology, thereby increasing the probability of successful energy transmission path planning and improving energy transmission efficiency.

[0043] In some embodiments, Figure 1As shown, the energy router may also include an energy metering component 104. The energy metering component 104 is capable of counting energy information of each energy port. In some embodiments, the energy metering component 104 measures the amount of electricity flowing into or out of each port. In some embodiments, during energy transmission, during the time period from when the energy transmission switch is turned on to when it is turned off, the duration t is recorded, and the mean power p of the transmission time period is multiplied by the time t, and the amount of electricity in the time period can be calculated, and the energy transmitted can be measured. In some embodiments, the PLC data may include information such as the target address, source address, transmission amount, and real-time voltage, current, and power of the energy. Based on the statistical results of each port by the energy metering component 104, statistics of end-to-end energy transmission can be achieved in combination with the information in the PLC data.

[0044] In some embodiments, Figure 1 As shown, the energy router may also include an energy conversion component 105 located between energy ports and performing at least one of AC conversion or voltage conversion. Since the voltage and AC / DC conditions at both ends of the energy router may be different, energy conversion is required, such as 400V to 48V. In some embodiments, the energy conversion component 105 can realize the AC / DC / high and low voltage conversion functions. In some embodiments, the energy conversion component 105 can be an inverter.

[0045] Such an energy router can take into account the different network environments on both sides of the energy transmission network, expanding the application scope of the energy router.

[0046] In some embodiments, Figure 1 As shown, the energy router may also include a cross-voltage conversion component 106. Since PLC data faces voltage coupling problems when crossing voltages, that is, energy data cannot be directly transmitted across voltages, after voltage conversion, the carrier characteristics will disappear and energy data cannot be reflected. In some embodiments, energy data can be bridged on both sides of different voltages by adding inductance in a voltage coupling or current coupling manner. Such an energy router can avoid PLC data loss caused by cross-voltage and ensure the reliability of energy network data transmission.

[0047] In other embodiments, the cross-voltage conversion component 106 can receive a message of PLC data from a port and send it to a routing component; the energy transmission path generated by the routing component is encapsulated into a message of PLC data according to the output voltage. The input end of the cross-voltage conversion component 106 is located between the input port of the energy router and the input end of the energy conversion component 105, and the output end of the cross-voltage conversion component 106 is located between the output port of the energy router and the output end of the energy conversion component 105, so that the PLC data is stripped during the voltage conversion process to avoid data loss. In some embodiments, the PLC data can also be processed according to demand, such as generating a new source EIP address and a target EIP address, and attaching them to the transmission protocol message, and then transmitting them to the other side voltage with a new protocol message, thereby realizing the update of PLC data and improving the flexibility of data transmission.

[0048] In some embodiments, Figure 1 As shown, the energy router may further include: a data processing component 107, which can form an energy information communication transmission and energy Internet protocol framework based on the architecture division of the application layer, the transport layer, the network layer, and the link layer.

[0049] In some embodiments, Figure 2 As shown, the data processing component 107 may include:

[0050] The application layer subcomponent is capable of generating application data; parsing the application data from the transport layer subcomponent; wherein the application data includes at least one of energy data, control data, status data or fault data.

[0051] The transport layer subcomponent can encapsulate the transport layer data packet according to the application data and the predetermined transport layer protocol; and parse the transport layer data packet from the network layer subcomponent. In some embodiments, the transport layer subcomponent can be compatible with CAN, Modbus, BACNet, LonWorks, etc.

[0052] The network layer subcomponent can generate a network layer data packet based on the transport layer data packet, MAC address and EIP address; and parse the network layer data packet from the link layer subcomponent.

[0053] The link layer subcomponent can generate PLC data packets based on network layer data packets; and parse PLC data packets from the energy network.

[0054] In the actual transmission of energy data, each layer of data is encapsulated from top to bottom to form a data packet. The final data packet will be as follows: Figure 3 The application data, source MAC address, destination MAC address, source EIP address, destination EIP address, protocol type, checksum and other information are shown.

[0055] Such energy routers draw on the IP network hierarchical architecture and use the following methods to generate, analyze and transmit data: Figure 2 The layered processing method shown in ensures the feasibility and reliability of data transmission.

[0056] In some embodiments, the PLC data message may be as follows: Figure 3 As shown, including:

[0057] PLC header information, in some embodiments, the PLC communication technology identifier occupies 1 byte and identifies the PLC communication technology used by the energy information;

[0058] EIP header information includes source EIP address and destination EIP address. In some embodiments, EIP header information occupies 8 bytes, of which source EIP address and destination EIP address each occupy 4 bytes. EIP address is used to identify a unique address in the system network.

[0059] EICT header information, including source MAC address, destination MAC address, sequence number, protocol type and checksum information. In some embodiments, the EICT header information occupies 16 bytes, the source MAC address and destination MAC address each occupy 4 bytes, the sequence number, confirmation number, protocol type, and protocol version each occupy 1 byte, and the length and checksum each occupy 2 bytes. The MAC address is used to identify a unique device in the system network;

[0060] The application data field may include one or more of energy data, control data, status data or fault data as required.

[0061] This data message format can be coordinated with the hierarchical architecture of the energy router to ensure the feasibility and reliability of data transmission and improve the flexibility of data transmission content.

[0062] In some embodiments, energy routers can be connected to each other and to multiple end nodes to form a Figure 4 The energy network shown. The energy network may include multiple end nodes 411~41m, where m is a positive integer. The end node may be a power plant node or a user node, etc., which can perform at least one of generating electricity or consuming electricity. The energy network includes multiple energy routers 401~40n of any type mentioned above, where n is a positive integer. Each energy router is connected to at least two nodes in the end node and other energy routers to form an energy network topology.

[0063] Energy and PLC data can be transmitted in such an energy network. The energy router can plan the transmission path for energy according to the PLC data and connect the ports on the transmission path for energy transmission, so that energy can be flexibly transmitted in the energy network, facilitating the transaction of electricity and improving the flexibility of energy interaction.

[0064] In some embodiments, based on the energy network, flow charts of some embodiments of the energy interaction method are as follows: Figure 5 shown.

[0065] In step 501, the energy output terminal generates PLC data through the connected energy router. In some embodiments, the PLC data includes a destination address. The PLC data may also include a source address, a next hop address, a number of energy interactions, etc.

[0066] In step 502, the energy router that receives the PLC data determines the energy transmission path and the next hop address according to the destination address, connects the port for inputting the PLC data and the port connected to the next hop energy router address, and sends the PLC data to the next hop node.

[0067] In step 503, after receiving the PLC data, the next hop node determines whether it is the node of the destination address. If it is the node of the destination address, the planning of the entire path is completed and step 504 is executed; if it is not the node of the destination address, step 502 is continued.

[0068] In step 504, power transmission is performed according to the conductive path of the energy router.

[0069] In some embodiments, the PLC data can be transmitted synchronously with the electric energy to be exchanged, and a circuit is turned on as a next-hop node is determined. After reaching the destination node, the electric energy reaches the destination node.

[0070] In other embodiments, PLC data may be transmitted first, and power transmission may be performed after the path from the source end to the destination end is completed.

[0071] Through this method, energy and PLC data can be transmitted in the energy network. The energy router plans the transmission path for the energy according to the PLC data, and opens the ports on the transmission path for energy transmission, so that energy can be flexibly transmitted in the energy network, facilitating the transaction of electric energy and improving the flexibility of energy interaction.

[0072] The flowcharts of some embodiments of the operation method of the energy router disclosed in the present invention are as follows: Figure 6 shown.

[0073] In step 601, PLC data and energy are received, wherein the PLC data includes a destination address. In some embodiments, the PLC data may also include a source address and energy transmission amount.

[0074] In step 602, the energy transmission path is determined according to the PLC data and the stored routing information. In some embodiments, the destination address can be determined according to the PLC data, and the energy transmission path can be determined based on the shortest path algorithm according to the stored routing information, thereby determining the next hop address.

[0075] In step 603, according to the determined port associated with the energy transmission path, the energy transmission switch of the port is turned on, so that the electric energy input to the energy router is output from the turned-on port.

[0076] In step 604, the electric energy input into the energy router is output from the turned-on port.

[0077] Through this method, the energy router can receive energy and PLC data, plan the transmission path for energy according to the PLC data, and open the ports on the transmission path for energy transmission, so that energy can be flexibly transmitted in the energy network as needed, facilitating the transaction of electricity and improving the flexibility of energy interaction.

[0078] In some embodiments, the energy router can measure at least one of the real-time energy output of the source address of the energy or the real-time energy input of the destination address based on the duration of each port being turned on and the average power during the transmission process. In some embodiments, the energy router can measure the amount of electricity flowing into or out of each port. For example, during energy transmission, during the time period from when the energy transmission switch is turned on to when it is turned off, the duration t is recorded, and the average power p of the transmission time period is multiplied by the time t, so that the amount of electricity in the time period can be calculated, and the energy transmitted can be measured.

[0079] Through this method, accurate measurement of energy input and output in distributed energy networks can be achieved, ensuring fair transactions between users.

[0080] In some embodiments, the energy router can perform at least one of AC conversion or voltage conversion according to the energy attributes of the energy input port and the energy attributes of the energy output port, wherein the energy attributes include DC, AC and voltage values. By using such a method, the problem of different network environments on both sides of the energy transmission network can be taken into account, and the application scope of the energy router is expanded.

[0081] In some embodiments, the energy router can extract the application data in the PLC data message from the port before AC conversion and voltage conversion, so as to determine the energy transmission path according to the stored routing information; re-encapsulate the application data into a PLC data message and output it through the energy output port. Through this method, the PLC data can be stripped during the voltage conversion process to avoid the loss of PLC data caused by cross-voltage, ensure the reliability of energy network data transmission; realize the update of PLC data, and improve the flexibility of data transmission.

[0082] In some embodiments, when the energy router cannot generate a transmission path based on the stored routing information, it sends broadcast information to other routers through the port, and updates the stored routing information based on the received path feedback, wherein the energy router that receives the broadcast message feeds back its own stored routing information associated with the destination address; and determines the energy transmission path based on the updated routing information.

[0083] Through this method, the energy router can obtain routing information from other network nodes by broadcasting information when its own network topology is incomplete, and then supplement its own stored network topology, increase the probability of successful energy transmission path planning, and improve energy transmission efficiency.

The processor 702 is used to execute the instructions stored in the memory, which can enable energy to be flexibly transmitted in the energy network according to demand, facilitate the transaction of electric energy, and improve the flexibility of energy interaction.
