Description

Technical Field

[0001] The present invention relates to the field of information sharing technology, and in particular to the secure sharing of flexible load information in a power system, and more specifically to a multi-level flexible load cluster information sharing method and system based on blockchain technology. Background Art

[0002] With the development of smart grids, the proportion of flexible loads in power systems has gradually increased. For example, electric vehicles, smart home devices, distributed energy, etc. are all flexible loads in power systems. The flexible loads are adjustable and dispatchable, which can effectively balance the supply and demand of the power grid and improve the flexibility and stability of the power grid system.

[0003] However, the traditional flexible load information sharing method has many problems and is difficult to meet the needs of efficient collaborative management of large-scale flexible load clusters. It has the following problems:

[0004] 1) Traditional information sharing methods usually rely on centralized databases or servers, and the data of each flexible load device is stored in different systems, forming "data islands". This decentralized data storage method makes it difficult to integrate and share data, limiting the value of data utilization.

[0005] 2) In the traditional way, the data collection, transmission and storage process lacks transparency, and the parties involved cannot verify the authenticity and integrity of the data. This not only affects the credibility of the data, but also increases the difficulty of data management and auditing.

[0006] 3) Traditional centralized systems have limitations in scalability. As the number of flexible load devices increases, the performance and reliability of centralized systems will gradually decline, making it difficult to meet the management needs of large-scale clusters. In addition, the access and management of new devices also require high costs and technical support.

[0007] 4) Flexible load equipment involves users’ personal privacy data, such as electricity usage habits, location information, etc. Traditional information sharing methods lack effective privacy protection mechanisms, and users’ data may be obtained and used by unauthorized third parties, infringing on users’ privacy rights.

[0008] It can be seen that the existing information sharing methods have many problems in data silos, transparency, scalability, and privacy security protection, which are very challenging for the management of large-scale flexible load clusters in smart grids. Therefore, how to improve the efficient coordination efficiency of flexible load clusters, achieve efficient and secure information sharing, and solve the problems brought by the above traditional technologies are technical problems that need to be solved urgently.

[0038] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0039] Figure 1 is a flowchart of a multi-level flexible load cluster information sharing method based on blockchain according to an embodiment of the present invention. Figure 1 As shown, the implementation steps are as follows:

[0040] Step S1: Building a blockchain network includes network construction, node configuration, creation block, node registration and synchronization.

[0041] Among them, network construction includes building a consortium blockchain network to ensure that various power grid control platforms, load aggregators, and flexible load nodes can be connected through the network.

[0042] Among them, node configuration includes configuring blockchain software within each sub-cluster to ensure that the nodes can operate the blockchain network normally. The power grid control platform node is responsible for supervision, the load aggregator node is responsible for accounting and verification, and the flexible load node is responsible for uploading data to the chain.

[0043] Among them, the genesis block includes the genesis block for creating a subcluster, which contains the basic information of the subcluster (such as the subcluster ID, member list, etc.).

[0044] Among them, node registration and synchronization include each node registering with the genesis block and generating the node's public key and private key. Each node starts from the genesis block and synchronizes the blockchain ledger to ensure that the data of all nodes is consistent.

[0045] Step S2: Load demand information release includes demand generation, demand release, and demand broadcast.

[0046] Among them, demand generation: load aggregators generate load demand according to power grid demand, including demand ID, publisher ID, release time, demand type, demand parameters, deadline, etc. Usually, the minimum unit time period of flexible load regulation is 1 hour, and the method preferably sets a block to be generated once every 1 hour. After a transaction is executed, the load agent node completes the accounting and timestamps the block to prove that all transactions are valid to ensure the traceability of all transactions afterwards. The block body mainly contains the load information of this period and the load that the flexible load users are expected to respond to in the next period and the load demand of the load aggregator.

[0047] Among them, demand release: the aggregator releases the load demand through the smart contract and stores the demand information on the blockchain.

[0048] Among them, demand broadcast: the smart contract broadcasts the load demand to all load users to ensure that users can receive the demand information.

[0049] Step S3: Flexible load users respond to demand, including demand reception and load data upload.

[0050] Among them, demand reception includes that the load user receives load demand information through a smart contract.

[0051] Among them, uploading load data to the chain includes users adjusting load generation data according to the availability and demand parameters of their own equipment, including response ID, user ID, response time, response parameters, and timestamp.

[0052] Step S4: Data confirmation and verification include generation confirmation, load confirmation, and recording results.

[0053] Among them, generating confirmation includes the aggregator confirming the user's response to the transaction through a smart contract and generating confirmation information, including confirmation ID, confirmation time, confirmer ID, confirmation status, execution time, execution results, etc.

[0054] Among them, load confirmation includes confirming the load based on the load data uploaded by the flexible load user's meter.

[0055] Among them, recording results includes recording user load data results on the blockchain to ensure the transparency and non-tamperability of the data.

[0056] Step S5: Data query and analysis, including the power grid dispatch center or other authorized agencies can query the operation data through the cluster's blockchain network, and the load aggregator can only query the operation data of this node and its subordinate aggregators or flexible load users.

[0057] like Figure 2 The figure shows the blockchain sub-cluster structure of an embodiment of the present invention. Based on the multi-level flexible load cluster, the blockchain network is constructed including network construction, node configuration, creation block, node registration and synchronization.

[0058] Among them, network construction includes building a consortium blockchain network to ensure that various power grid control platforms, load aggregators, and flexible load nodes can be connected through the network.

[0059] Among them, node configuration includes configuring blockchain software within each sub-cluster to ensure that the nodes can operate the blockchain network normally. The power grid control platform node is responsible for supervision, the load aggregator node is responsible for accounting and verification, and the flexible load node is responsible for uploading data to the chain.

[0060] Among them, the genesis block includes the genesis block for creating a subcluster, which contains the basic information of the subcluster (such as the subcluster ID, member list, etc.).

[0061] Among them, node registration and synchronization include each node registering with the genesis block and generating the node's public key and private key. Each node starts from the genesis block and synchronizes the blockchain ledger to ensure that the data of all nodes is consistent.

[0062] The overall architecture of blockchain is as follows: Figure 3 As shown:

[0063] Among them, the security and privacy protection layer ensures that all data and operations in the blockchain platform are sufficiently secure through encryption, identity authentication, authorization control and other technologies to prevent data leakage, malicious attacks and identity theft.

[0064] Among them, the data layer stores all transaction data, block data, hash values ​​and other information, and ensures the data is tamper-proof and traceable. All load demand information, user response information, timestamps, etc. are stored through the blockchain to ensure data integrity and security. Contains block data storage: load demand and user response data are stored, and each block contains information such as demand ID, response time, and response volume; Off-chain storage: some large-scale data (such as load regulation logs, user device status, etc.) can be stored outside the chain and associated with blockchain data through hash values ​​to ensure data integrity. For example, the personal privacy data of load users (such as electricity usage habits) can be stored outside the chain through encryption, and the hash value is recorded on the blockchain; Hash value storage: Each transaction, load demand and response data generates a hash value and is permanently stored to ensure the immutability of transaction data.

[0065] Among them, the network layer is responsible for the communication and data synchronization between nodes in the blockchain network, ensuring that nodes can synchronize blockchain data efficiently and securely. It includes node communication: different participants (load aggregators, power grid dispatching platforms, load users) communicate through the blockchain network to transmit load demand information and user response information; block propagation and synchronization: the blockchain platform needs to ensure that the load demand and response data are updated synchronously between nodes to ensure data consistency of all nodes; network protocol: defines how nodes communicate with each other and how to transmit data to ensure that data can be effectively broadcast and propagated.

[0066] Among them, the consensus layer ensures the decentralization of the blockchain system, and ensures that each node reaches a consensus on transactions and data without central control through the consensus mechanism. Including consensus mechanism: PBFT (Practical Byzantine Fault Tolerance) is used to verify the validity of load demand and response data to ensure the consistency of transactions. Different nodes (such as load aggregators, power grid dispatching platforms) decide whether to accept new load demand and response data through the consensus mechanism; Block generation and verification: Through the consensus mechanism, new blocks are generated and added to the blockchain. Each block contains load demand and user response data for a period of time.

[0067] Among them, the contract layer ensures the security, decentralization and enthusiasm of participants in the blockchain network through economic incentives. The incentive layer encourages nodes (such as verification nodes, load users) to provide resources for the system through a reward mechanism. Including load demand release and broadcast: load aggregators release load demands through smart contracts and broadcast demand information to all load users. Smart contracts set demand parameters, time periods, response strategies, etc. through rules; response verification: when load users respond to load demands, smart contracts will verify based on the actual response (such as response volume, response time) to determine whether the response meets the demand requirements; reward mechanism: after verifying that the load user's response is valid, the smart contract automatically executes the reward mechanism and issues rewards or electricity discounts to load users.

[0068] Among them, the application layer is directly facing users such as load aggregators, load users, and power grid dispatching platforms, providing various operations and interactive interfaces to handle specific business needs.

[0069] like Figure 4 As shown in the figure, the specific structure of the flexible load user block based on the present invention is provided in the block header information, which includes the version number, timestamp, parent block ID, block ID / Merkle and other information, and also includes the current period, aggregator demand, actual load value of flexible load, response value, load response benefit information; next period, aggregator demand information, flexible load response value; load response expected benefit information. The constructed block information stores the information of each node of the synchronization system to ensure the transparency and non-tamperability of the data.

[0070] 2) Load demand information release includes demand generation, demand release, and demand broadcast. Usually, the minimum unit time period of flexible load control is 1 hour, and the method is preferably set to generate 1 block every 1 hour. After a transaction is completed, the load agent node with the largest virtual average profit value completes the accounting and stamps the block to prove that all transactions are valid to ensure the traceability of all transactions afterwards. The block body mainly contains the load information of this period and the load demand of the flexible load users and load aggregators that are expected to respond to the load in the next period. The block data structure is as follows: Figure 3 shown.

[0071] Among them, demand generation includes load aggregators generating load demand based on power grid demand, including demand ID, publisher ID, release time, demand type, demand parameters, reward mechanism, deadline, etc.

[0072] Among them, demand release includes the aggregator publishing load demand through smart contracts and storing the demand information on the blockchain.

[0073] Among them, demand broadcasting includes the smart contract broadcasting load demand to all load users to ensure that users can receive demand information.

[0074] 3) Flexible load users respond to demand, including demand reception and load data uploading.

[0075] Among them, demand reception includes that the load user receives load demand information through a smart contract.

[0076] Among them, uploading load data to the chain includes users adjusting load generation data according to the availability and demand parameters of their own equipment, including response ID, user ID, response time, response parameters, and timestamp.

[0077] 4) Data confirmation and verification include generation confirmation, load confirmation, and recording results.

[0078] Among them, generating confirmation includes the aggregator confirming the user's response to the transaction through a smart contract and generating confirmation information, including confirmation ID, confirmation time, confirmer ID, confirmation status, execution time, execution results, etc.

[0079] Among them, load confirmation includes confirming the load based on the load data uploaded by the flexible load user's meter.

[0080] Among them, recording results includes recording user load data results on the blockchain to ensure the transparency and non-tamperability of the data.

[0081] 4) Data query and analysis, including the power grid dispatch center or other authorized agencies can query the operation data through the cluster's blockchain network, and the load aggregator can only query the operation data of this node and its subordinate aggregators or flexible load users.

[0082] The load demand release and response timing diagram is as follows: Figure 5 As shown in the figure: With the intervention of the blockchain trading platform, the process of publishing load demand and user response to demand has become more automated and transparent. The load aggregator publishes the load demand through the smart contract, and the blockchain trading platform records all transaction information and broadcasts it to all load users. After the load user responds, the platform will record the response information and verify the accuracy of the data through the blockchain to ensure the transparency and security of the entire power dispatch process. Finally, an analysis report is generated for the load aggregator and the user.

[0083] The present invention also provides a blockchain-based multi-level flexible load cluster information sharing system to implement the aforementioned blockchain-based multi-level flexible load cluster information sharing method.

[0084] The present invention also provides an electronic device, including a memory and a processor, wherein a computer program is stored in the memory, and the processor is used to execute the program in the memory to implement the aforementioned blockchain-based multi-level flexible load cluster information sharing method.

[0085] The present invention also provides a computer-readable storage medium, which stores a computer program for implementing the aforementioned blockchain-based multi-level flexible load cluster information sharing method.

[0086] In summary, the present invention provides a multi-level flexible load cluster information sharing method and system based on blockchain. By setting a blockchain structure, the immutability and security of data are ensured, data is prevented from being maliciously tampered with, and the data security of flexible load users in the power grid system is improved. Applied to the management of flexible load users in the power grid, all participants in the block network can view and verify the data, which improves the transparency and credibility of the information. In addition, blockchain technology is used to provide a variety of privacy protection mechanisms, so that users can participate in data sharing without exposing their identities, effectively protect users' privacy data, improve data security, and prevent these sensitive data from being obtained and used by unauthorized third parties. By setting the management method of the sub-cluster, the system performance and reliability are guaranteed to meet the data management needs of large-scale clusters.
