[0108] The following is a description of exemplary embodiments of the present application in conjunction with the accompanying drawings, including various details of the embodiments of the present application to facilitate understanding, which should be considered as merely exemplary. Therefore, it should be recognized by those of ordinary skill in the art that various changes and modifications can be made to the embodiments described herein without departing from the scope and spirit of the present application. Similarly, for the sake of clarity and conciseness, the description of well-known functions and structures is omitted in the following description.

[0109] Before introducing the various embodiments of the present invention, the blockchain network system for executing the blockchain-based power resource allocation method, device, electronic device and medium of the embodiment of the present invention is described. The nodes participating in the blockchain network system of the embodiment of the present invention include: ordinary computing and storage nodes, power user nodes and power seller nodes. Among them, ordinary computing and storage nodes are usually node devices in the blockchain network, which can store blockchain data and participate in the blockchain transaction request interaction process. The power user node can be the power user's power-consuming equipment, such as electric lighting equipment, electrical equipment and charging equipment. The power seller node can provide power equipment.

[0110] It should be noted that in the blockchain system provided in the embodiment of the present invention, the user node may also include the user smart meter node and the seller smart meter node, and the smart meter is a device that the State Grid has the right to install. The user smart meter may be a smart metering device installed on the user's power equipment. The seller's smart meter node may be a smart metering device installed on the seller's power generation equipment. The user smart meter node and the seller smart meter node may be blockchain nodes or may not be blockchain nodes, but may interact with the blockchain node through the interface provided by the blockchain node and participate in the blockchain network. Optionally, the user smart meter node may be a lightweight node deployed on the user's power equipment, and the seller smart meter node may be a lightweight node deployed on the seller's power generation equipment (for example, a lightweight node communication software development kit (SDK) may be installed on the user's smart meter and the seller's smart meter). The lightweight node is similar to a full node and is deployed with blockchain deployment data, such as smart contracts, consensus mechanisms, etc. Therefore, it can participate in the transaction request interaction process of the blockchain, but does not store all block data. When a lightweight node needs to query transaction data in the blockchain, it can obtain it from other nodes in real time and verify it in a set manner. Lightweight nodes have low hardware configuration requirements for the devices they are deployed on. Lightweight nodes can be integrated at the operating system level to control the hardware in the terminal device, and can interact with upper-level application software to provide blockchain support for the functions of the application software.

[0111] Figure 1It is a flowchart of a blockchain-based power resource allocation method performed by a node in a blockchain network according to an embodiment of the present application. This embodiment can be applicable to the situation of allocating power resources. Typically, this embodiment can be applicable to the situation where the blockchain allocates power resources and regulates prices based on the power demand of the power user and the power sales demand of the power seller. The blockchain-based power resource allocation method disclosed in this implementation can be executed by an electronic device that carries a node in a blockchain network, and specifically can be executed by a blockchain-based power resource allocation device, which can be implemented by software and / or hardware and configured in an electronic device. See Figure 1 The power resource allocation method based on blockchain and executed by a node in a blockchain network provided in this embodiment includes:

[0112] S110. Call the power dispatch smart contract to match the acquired power demand information of the power user with the power sales demand information of the power seller to obtain a matching result.

[0113] Among them, the power dispatch smart contract can store the power demand information of the power user and the power sales demand information of the power seller. The power demand information includes but is not limited to: expected power consumption and maximum power price; the power sales demand information includes but is not limited to: expected power sales and minimum power sales price. Since the power user expects to use electricity when the power price is lower than or equal to the maximum power price, and the current electricity price may be higher than the power user's maximum power price, or the current available power cannot meet the power user's current expected power consumption, the power user can first send the power demand information to the smart contract for storage so that electricity can be used when the conditions are met. For example, when a car owner wants to charge his new energy vehicle but is not in a hurry, he can set a maximum power price, and only connect to the power grid for charging when there is a power seller with a price lower than or equal to the maximum power price in the current market. Similarly, the electricity seller hopes to sell electricity to the grid when the electricity price is higher than or equal to the minimum electricity price, while the current electricity price may be lower than the seller's minimum electricity price, or the seller's current saleable electricity volume cannot meet the electricity consumption of the user. Therefore, the electricity seller can first send the electricity demand information to the smart contract for storage so that it can sell electricity to the grid when the conditions are met.

[0114] In an embodiment of the present application, the power dispatching smart contract receives the power demand information sent by the power user and the power selling demand information sent by the power seller, and stores them. The power dispatching smart contract matches the stored power demand smart contract and the power selling smart contract, which can be: each time the power demand information or the power selling demand information is received, the received power demand information is matched with the stored power selling demand information, or the received power selling demand information is matched with the stored power demand information, or when the number of received power demand information and power selling demand information meets the preset number, then the matching is performed. The matching principle can be that when the highest power price in the power demand information of the power user is less than or equal to the lowest power selling price in the power selling demand information of the power seller, and / or, when the expected power consumption in the power demand information of the power user is less than or equal to the expected power selling amount in the power selling demand information of the power seller, then the power demand information is considered to match the power selling demand information. The smart contract obtains and stores the matching results, which may include two matching results: successful matching and failed matching between the electricity demand information and the electricity sales demand information.

[0115] S120. In response to the electricity usage query transaction request of the electricity user, generate an electricity usage control instruction of the electricity user according to the matching result, so as to control the electricity usage behavior of the electricity user.

[0116] Among them, the electricity query transaction request can be a request sent by the electricity user to the node in the blockchain network when the electricity user needs electricity. The electricity query transaction request can be generated by the electricity user's smart meter and sent to the node in the blockchain network. Exemplarily, the electricity user's smart meter can query whether there is an available token in the electricity user's blockchain account. If not, the power is cut off. If it exists, the electricity query transaction request is sent regularly to access the power dispatch smart contract regularly to determine whether there is electricity sales demand information that matches the electricity demand information of the electricity user, and obtain instructions on whether electricity can be used. The node in the blockchain network generates the electricity control instruction of the electricity user based on the matching result of the smart contract to control the control behavior of the electricity user.

[0117] In an embodiment of the present application, a power usage control instruction of the power user is generated according to the matching result, including: if the matching result is a successful match, generating a power usage permission instruction of the power user; if the matching result is a failed match, generating a power usage prohibition instruction of the power user.

[0118] Exemplarily, when the matching result is successful, it means that there is electricity sales demand information that matches the electricity demand information of the electricity user, the lowest electricity sales price in the successfully matched electricity sales demand information is lower than or equal to the highest electricity price of the electricity user, and / or the expected electricity sales amount in the electricity sales demand information is greater than or equal to the expected electricity consumption of the electricity user, and the electricity seller can meet the needs of the electricity user, so an electricity use permission instruction is generated for the electricity user to allow the electricity user to use electricity. If the matching result is a failure, it means that the electricity seller cannot meet the needs of the electricity user, so in order to avoid the situation where the electricity user fails to use electricity, the node in the blockchain network generates a prohibition of electricity use instruction to prohibit the electricity user from using electricity.

[0119] S130. In response to the power selling query transaction request of the power seller, generate a power selling control instruction of the power seller according to the matching result, so as to control the power selling behavior of the power seller.

[0120] Among them, the power sale query transaction request can be a request sent to the node in the blockchain network when the power seller stores sellable electric energy. The power sale query transaction request can be generated by the smart meter of the power seller and sent to the node in the blockchain network. Exemplarily, the smart meter of the power seller can periodically send a power sale query transaction request to the node in the blockchain network to obtain instructions on whether the electric energy stored in the energy storage device of the power seller needs to be merged into the power grid. The node in the blockchain network generates the power sale control instruction of the power seller based on the matching result of the smart contract to control the power sale behavior of the power seller.

[0121] In an embodiment of the present application, a power selling control instruction of the power seller is generated according to the matching result, including: if the matching result is a successful match, generating a power selling permission instruction of the power seller; if the matching result is a failed match, generating a power selling prohibition instruction of the power seller.

[0122] Exemplarily, when the matching result is successful, it means that there is electricity demand information that matches the electricity sales demand information of the electricity seller, and the highest electricity price in the successfully matched electricity demand information is higher than or equal to the lowest electricity sales price of the electricity seller, and / or the expected electricity consumption of the electricity user is less than or equal to the expected electricity sales of the electricity seller. Therefore, the electricity seller's permission to sell electricity and sell electricity on the grid is generated to allow the electricity seller to sell electricity on the grid. If the matching result is a failure, it means that there is no electricity user demand that matches the electricity seller's demand. Therefore, in order to avoid the situation where the grid-connected electricity cannot be used in time and cause waste of resources, the nodes in the blockchain network generate a prohibition of electricity sales instructions to prohibit the electricity seller from selling electricity on the grid.

[0123] In an embodiment of the present application, if the matching result is a successful match, the method also includes: calling the power allocation smart contract to determine the actual electricity selling price; and charging according to the actual electricity selling price, the actual electricity consumption of the electricity user and the actual electricity sales of the electricity seller.

[0124] Exemplarily, if the match is successful, it means that the lowest electricity selling price in the electricity selling demand information is lower than or equal to the highest electricity price of the electricity user, and / or the expected electricity selling amount in the electricity selling demand information is greater than or equal to the expected electricity consumption of the electricity user. Therefore, the nodes in the blockchain network can call the power dispatching smart contract to determine the actual electricity selling price based on the price of either party, and calculate the electricity fee of the electricity user based on the actual electricity selling price and the electricity consumption of the electricity user, and calculate the electricity selling fee of the electricity seller based on the actual electricity selling price and the electricity selling amount of the electricity seller.

[0125] It should be noted that in the embodiment of the present application, the above-mentioned execution steps are only used to illustrate one implementation method, and the execution steps of S110, S120 and S130 are not specifically limited. It can also be that when a node in the blockchain network receives a power query transaction request from the power user, in response to the power query transaction request from the power user, the power dispatch smart contract is called to match the acquired power demand information of the power user with the power sales demand information of the power seller to obtain a matching result, and the power control instruction of the power user is generated according to the matching result to control the power consumption behavior of the power user. When a node in the blockchain network receives a power sales query transaction request from the power seller, in response to the power sales query transaction request from the power seller, the power dispatch smart contract is called to match the acquired power sales demand information of the power seller with the power demand information of the power user to obtain a matching result, and the power sales control instruction of the power seller is generated according to the matching result. In addition, there is no specific limitation on the execution steps of S120 and S130. The power user sends a power query transaction request and the nodes in the blockchain network respond to the power query transaction request, and the power seller sends a power sales query transaction request and the nodes in the blockchain network respond to the power sales query transaction request, which can be executed asynchronously. Since there is redundancy in the power grid, it can generally meet the current power demand of the power user. Therefore, when S120 and S130 are not executed synchronously, the normal power consumption of the power user can still be guaranteed. Therefore, the power consumption of the power user can be controlled first, and then the power seller can be controlled to sell power on the grid, or the power seller can be controlled to sell power on the grid first, and then the power user can be controlled to use power.

[0126] The technical solution of the embodiment of the present application matches electricity demand information and electricity sales demand information by calling a smart contract, and responds to the electricity user's query transaction request to control the electricity consumption behavior according to the matching result, and responds to the electricity sales query transaction request of the electricity seller to control the electricity sales behavior of the electricity seller according to the matching result, thereby overcoming the difficulty in reaching a consensus on the grid-connected power volume of each electricity seller and the problem of fixed electricity prices, and realizing the effect of reasonably allocating electricity resources according to the electricity demand of the electricity user and the electricity sales volume of the electricity seller, and dynamically adjusting the electricity price.

[0127] Figure 2 This is a flowchart of another method for allocating electric power resources based on blockchain and executed by a node in a blockchain network according to an embodiment of the present application. This embodiment is an optional solution proposed on the basis of the above embodiment. Figure 2 , the power resource allocation method based on blockchain provided in this embodiment includes:

[0128] S210. Call the power dispatch smart contract to match the acquired power demand information of the power user with the power sales demand information of the power seller to obtain a matching result.

[0129] S220 . In response to the electricity usage query transaction request of the electricity user, generate an electricity usage control instruction of the electricity user according to the matching result, so as to control the electricity usage behavior of the electricity user.

[0130] S230. In response to the power selling query transaction request of the power seller, generate a power selling control instruction of the power seller according to the matching result, so as to control the power selling behavior of the power seller.

[0131] S240. Obtain the actual power consumption of the power user through the smart meter of the power user, and store the actual power consumption on the chain as transaction data.

[0132] For example, Figure 3 As shown, the smart meter of the electricity user can obtain the electric energy consumed by the electrical equipment, determine the actual electricity consumption of the electricity user, and store the actual electricity consumption as transaction data on the chain, so that the nodes in the blockchain network can calculate the electricity bill based on the actual electricity consumption, and perform operations such as statistical analysis of the total actual electricity consumption.

[0133] S250. Obtain the actual electricity sales amount of the electricity seller through the smart meter of the electricity seller, and store the actual electricity sales amount on the chain as transaction data.

[0134] For example, Figure 3As shown, the smart meter of the electricity seller can obtain the electricity sold by the power transmission equipment, determine the actual electricity sales amount of the electricity seller, and store the actual electricity sales amount on the chain as transaction data, so that the nodes in the blockchain network can calculate the electricity bill based on the actual electricity sales amount, and perform operations such as statistical analysis of the total actual electricity sales amount.

[0135] In the embodiment of the present application, there is no specific limitation on the execution steps of S240 and S250. S240 may be executed first, S250 may be executed first, or both may be executed at the same time.

[0136] like Figure 3 As shown in the figure, the power company obtains the bill of the electricity user and the legal currency of the electricity user by accessing the smart contract on the blockchain network. It obtains the revenue of the electricity seller by accessing the smart contract on the blockchain network and pays the legal currency to the electricity seller.

[0137] S260: If it is detected that any power seller has no saleable electricity, the power allocation smart contract is called to clear the power sales demand information of the power seller to remove the power seller from the shelves.

[0138] Exemplarily, for a power seller that does not have a saleable amount of electricity, the power sales demand information of the power seller is cleared from the power dispatch smart contract to avoid still matching the power sales demand information with the electricity demand information, thereby reducing the matching efficiency. Therefore, in an embodiment of the present application, if a node in the blockchain network detects that any power seller does not have a saleable amount of electricity, the power dispatch smart contract is called to clear the power sales demand information. The detection method may be that after generating the power seller's permission to sell electricity instruction, the power seller obtains the permission to sell electricity instruction through timed access, detects whether the power seller is connected to the grid to sell electricity, and stores the actual amount of electricity sold on the chain. If it is detected that the power seller is not connected to the grid to sell electricity, and the actual amount of electricity sold is stored on the chain, it is determined that the power seller does not have a saleable amount of electricity.

[0139] S270: If it is detected that any electricity user has been successfully matched and has not used electricity within the time limit, the power dispatching smart contract is called to clear the electricity demand information of the electricity user to remove the electricity user from the shelves.

[0140] Exemplarily, for the electricity user who has successfully matched but has not used electricity within the time limit, the electricity demand information of the electricity user is cleared from the power dispatch smart contract to avoid still matching the electricity demand information with the electricity sales demand information, thereby reducing the matching efficiency. Therefore, in an embodiment of the present application, if a node in the blockchain network detects that any electricity user has successfully matched with the electricity seller, but has not used electricity for more than a preset time, it is determined that the electricity user currently has no electricity demand, and therefore, the power dispatch smart contract is called to clear the electricity demand information. The detection method can be that after generating an instruction to allow electricity use, the user obtains the instruction to allow electricity use through timed access, detects whether the electricity user is using electricity, and stores the actual electricity consumption on the chain. If it is detected that the electricity user has no equipment consuming electricity within the preset time, or the actual electricity consumption is not stored on the chain, it is determined that the electricity user has timed out and has not used electricity.

[0141] It should be noted that in the embodiment of the present application, there is no specific limitation on the execution steps of S260 and S270. S260 may be executed first, S270 may be executed first, or both may be executed at the same time.

[0142] In the embodiment of the present application, by obtaining the actual power consumption and the actual power sales, the electricity fee is accurately calculated based on the actual power consumption and the actual power sales and the actual power sales price, or used for total actual power consumption or total actual power sales statistics. When it is detected that the power user has not used electricity for an extended period of time, the power user's power demand information is cleared from the power dispatch smart contract, and when the power seller has no power to sell, the power seller's power sales demand information is cleared from the power dispatch smart contract, thereby avoiding the problem of matching supply and demand for useless power sales demand information and useless power demand information, reducing matching efficiency and response speed, and increasing the burden on the processor.

[0143] Figure 4 It is a flowchart of a blockchain-based power resource allocation method performed by the power user according to an embodiment of the present application. This embodiment can be applicable to the situation of allocating power resources. Typically, this embodiment can be applicable to the situation where the blockchain allocates power resources and regulates prices based on the power user's power demand and the power seller's power sales demand. The blockchain-based power resource allocation method disclosed in this implementation can be executed by an electronic device that carries the power user's node, specifically by a blockchain-based power resource allocation device, which can be implemented by software and / or hardware and configured in an electronic device. For details not fully described in the embodiments of the present application, such as glossaries, etc., please refer to the above embodiments. See. Figure 4 The power resource allocation method based on blockchain provided by the power user in this embodiment includes:

[0144] S310. Send local electricity demand information to the blockchain network to instruct the blockchain network to call the power dispatch smart contract to match the electricity demand information with the electricity sales demand information of the electricity seller.

[0145] Among them, the power dispatch smart contract can store the power demand information of the power user and the power sales demand information of the power seller. The power demand information includes but is not limited to: expected power consumption and maximum power price; the power sales demand information includes but is not limited to: expected power sales and minimum power sales price. Since the power user expects to use electricity when the power price is lower than or equal to the maximum power price, and the current power price may be higher than the maximum power price of the power user, or the current available power cannot meet the current expected power consumption of the power user, the power user can first send the power demand information to the smart contract for storage, so as to use electricity when the conditions are met. Similarly, the power seller expects to sell electricity on the grid when the power price is higher than or equal to the minimum power price, and the current power price may be lower than the minimum power price of the power seller, or the current available power of the power seller cannot meet the power consumption of the power user, so the power seller can first send the power sales demand information to the smart contract for storage, so as to sell electricity on the grid when the conditions are met.

[0146] Exemplarily, the power user sends power demand information to the blockchain network so that the nodes in the blockchain network match the power demand information sent by the power user with the power sales demand information sent by the power seller. When there is a power seller that meets the power user's power demand, the power user is allowed to use electricity. The power user can send power demand information to the blockchain network when there is a current power demand, or send power demand information to the blockchain network in advance when there is no power demand at present but there is a power demand at some point in the future.

[0147] In an embodiment of the present application, the power dispatching smart contract receives the power demand information sent by the power user and the power selling demand information sent by the power seller, and stores them. The power dispatching smart contract matches the stored power demand smart contract and the power selling smart contract, which can be: each time the power demand information or the power selling demand information is received, the received power demand information is matched with the stored power selling demand information, or the received power selling demand information is matched with the stored power demand information, or when the number of received power demand information and power selling demand information meets the preset number, then the matching is performed. The matching principle can be that when the highest power price in the power demand information of the power user is less than or equal to the lowest power selling price in the power selling demand information of the power seller, and / or, when the expected power consumption in the power demand information of the power user is less than or equal to the expected power selling amount in the power selling demand information of the power seller, then the power demand information is considered to match the power selling demand information. The smart contract obtains and stores the matching results, which may include two matching results: successful matching and failed matching between the electricity demand information and the electricity sales demand information.

[0148] S320. Send an electricity usage query transaction request to the blockchain network to instruct the blockchain network to generate an electricity usage control instruction for the electricity user based on the matching results.

[0149] The power query transaction request may be a request sent by the power user to a node in the blockchain network when the power user needs to use electricity. The power query transaction request may be generated by the power user's smart meter and sent to the node in the blockchain network. The power user's smart meter may periodically send power query transaction requests to periodically access the power dispatch smart contract to determine whether there is power sales demand information that matches the power user's demand information and obtain instructions on whether electricity can be used. The node in the blockchain network generates the power user's power control instructions based on the matching results of the smart contract to control the power user's control behavior.

[0150] In an embodiment of the present application, the method further includes: if the power consumption control instruction is an allowed power consumption control instruction, obtaining the actual power consumption through a local smart meter, and sending the actual power consumption to the blockchain network.

[0151] For example, the smart meter of the electricity user can obtain the actual electric energy consumed by the electrical equipment, determine the actual electricity consumption of the electricity user, and store the actual electricity consumption as transaction data on the chain, so that the nodes in the blockchain network can calculate the electricity bill based on the actual electricity consumption, and perform operations such as statistical analysis of the total actual electricity consumption.

[0152] In an embodiment of the present application, before sending an electricity usage query transaction request to the blockchain network, it also includes: querying the electricity user through the local smart meter whether there are available elements; if so, triggering the execution of the electricity usage query transaction request sending operation; otherwise, disconnecting the grid connection.

[0153] The available element may be a token in the blockchain account of the electricity user. The electricity user uses the local smart meter to query whether there is an available token in the blockchain account of the electricity user. If not, the power is cut off. If so, a power query transaction request is sent to the node in the blockchain network to request power.

[0154] The embodiment of the present application sends local electricity demand information to the blockchain network to instruct the blockchain network to call the power allocation smart contract, match the electricity demand information and the electricity sales demand information, and send an electricity query transaction request to the blockchain network so that the blockchain network controls electricity consumption according to the matching results, thereby overcoming the problem that the electricity price is fixed and it is difficult to meet the needs of the electricity users and sellers, and achieving the effect of allocating electricity resources according to the electricity demand of the electricity users and the electricity sales amount of the electricity sellers, and dynamically adjusting the electricity price.

[0155] Figure 5 This is a flowchart of a blockchain-based power resource allocation method performed by a power seller according to an embodiment of the present application. This embodiment can be applicable to the situation of allocating power resources. Typically, this embodiment can be applicable to the situation where the blockchain allocates power resources and regulates prices based on the power demand of the power user and the power sales demand of the power seller. The blockchain-based power resource allocation method disclosed in this implementation can be executed by an electronic device that carries a power seller node, specifically by a blockchain-based power resource allocation device, which can be implemented by software and / or hardware and configured in an electronic device. See Figure 5 The blockchain-based power resource allocation method provided by the power seller in this embodiment includes:

[0156] S410. Send local electricity sales demand information to the blockchain network to instruct the blockchain network to call the power dispatch smart contract to match the local electricity sales demand information with the electricity user's electricity demand information.

[0157] Among them, the power dispatch smart contract can store the power demand information of the power user and the power sales demand information of the power seller. The power demand information includes but is not limited to: expected power consumption and maximum power price; the power sales demand information includes but is not limited to: expected power sales and minimum power sales price. Since the power user expects to use electricity when the power price is lower than or equal to the maximum power price, and the current power price may be higher than the maximum power price of the power user, or the current available power cannot meet the current expected power consumption of the power user, the power user can first send the power demand information to the smart contract for storage, so as to use electricity when the conditions are met. Similarly, the power seller expects to sell electricity on the grid when the power price is higher than or equal to the minimum power price, and the current power price may be lower than the minimum power price of the power seller, or the current available power of the power seller cannot meet the power consumption of the power user, so the power seller can first send the power sales demand information to the smart contract for storage, so as to sell electricity on the grid when the conditions are met.

[0158] Exemplarily, the power seller sends power demand information to the blockchain network so that the nodes in the blockchain network match the power demand information with the power demand information sent by the power user. When the power demand information of the power user matches the power seller's power demand information, the power seller is allowed to sell electricity in the grid. The power seller can send the power demand information to the blockchain network when there is currently saleable power stored, or when there is no saleable power currently but it can be stored in the future.

[0159] In an embodiment of the present application, the power dispatching smart contract receives the power demand information sent by the power user and the power selling demand information sent by the power seller, and stores them. The power dispatching smart contract matches the stored power demand smart contract and the power selling smart contract, which can be: each time the power demand information or the power selling demand information is received, the received power demand information is matched with the stored power selling demand information, or the received power selling demand information is matched with the stored power demand information, or when the number of received power demand information and power selling demand information meets the preset number, then the matching is performed. The matching principle can be that when the highest power price in the power demand information of the power user is less than or equal to the lowest power selling price in the power selling demand information of the power seller, and / or, when the expected power consumption in the power demand information of the power user is less than or equal to the expected power selling amount in the power selling demand information of the power seller, then the power demand information is considered to match the power selling demand information. The smart contract obtains and stores the matching results, which may include two matching results: successful matching and failed matching between the electricity demand information and the electricity sales demand information.

[0160] S420. Send a power sales query transaction request to the blockchain network to instruct the blockchain network to generate a power sales control instruction for the power seller based on the matching results.

[0161] The power query transaction request may be a request sent by the power user to a node in the blockchain network when the power user needs to use electricity. The power query transaction request may be generated by the power user's smart meter and sent to the node in the blockchain network. The power user's smart meter may periodically send power query transaction requests to periodically access the power dispatch smart contract to determine whether there is power sales demand information that matches the power user's demand information and obtain instructions on whether electricity can be used. The node in the blockchain network generates the power user's power control instructions based on the matching results of the smart contract to control the power user's control behavior.

[0162] In an embodiment of the present application, the method further includes: if the power consumption control instruction is a control instruction allowing power sales, then through the local smart meter, a grid-connected operation is performed on the power stored in the local energy storage device, and the actual power sales amount is sent to the blockchain network.

[0163] For example, the smart meter of the electricity seller can obtain the actual electricity sold by the power transmission equipment, determine the actual electricity sales amount of the electricity seller, and store the actual electricity sales amount as transaction data on the chain, so that the nodes in the blockchain network can calculate the electricity bill based on the actual electricity sales amount, and perform statistical analysis of the total actual electricity sales amount and other operations.

[0164] The embodiment of the present application sends local electricity sales demand information to the blockchain network to instruct the blockchain network to call the power allocation smart contract, match the electricity demand information and the electricity sales demand information, and send a land query transaction request to the blockchain network so that the blockchain network controls the power connection according to the matching result, thereby overcoming the problem of difficulty in reaching a consensus on the grid-connected power of each electricity seller, and achieving the effect of allocating power resources according to the power demand of the power user and the power sales amount of the power seller, and dynamically adjusting the power price.
