[0026] Embodiment 1

[0027] like Figure 1 As shown, in this embodiment, a high and low voltage distribution system data management method based on blockchain is provided, including:

[0028] Collecting power distribution system operation data, calibrating the power distribution system operation data, and obtaining calibrated power distribution data;

[0029] As a preferred implementation, the process of collecting distribution system operation data includes:

[0030] Authenticate all devices in the high and low voltage power distribution system, generate a unique identity certificate for each device, and obtain the power distribution system operation data in real time through the device. The devices include smart meters, sensors, and controllers. The identity certificate is encrypted and decrypted through the public and private key system of the blockchain.

[0031] As a preferred implementation manner, the process of calibrating the power distribution system operation data to obtain calibrated power distribution data includes:

[0032] The power distribution system operation data is classified based on the equipment's belonging area to obtain different categories of power distribution system operation data, and the target standard data corresponding to the different categories are extracted from the historical data information library; based on the target standard data, it is determined whether there are abnormalities in the corresponding category of power distribution system operation data, and the abnormal data is eliminated to obtain calibrated distribution data.

[0033] As a preferred implementation manner, the process of calibrating the power distribution system operation data to obtain calibrated power distribution data further includes:

[0034] Abnormal data is marked, the identity certificate of the corresponding device is extracted, and the corresponding device is continuously monitored. A secondary proofreading is performed based on the monitoring data. If the proofreading fails, the device is marked and the device parameters are adjusted according to the proportion of abnormal data.

[0035] Creating a blockchain network based on a cloud server, splitting and encrypting the calibration distribution data, and storing it in the blockchain network;

[0036] As a preferred implementation, the blockchain network adopts a hybrid chain architecture; the calibration distribution data is split to obtain public data and private data; and the private data and the public data are stored in a private chain and a public chain respectively.

[0037] As a preferred implementation, the area to which the privacy data belongs is determined based on the device ID in the distribution system operation data, the privacy data is grouped according to the area, and an asymmetric encryption algorithm is used to encrypt the privacy data in different areas respectively. The encrypted privacy data is sharded and stored in different locations respectively, and a hash value of each shard data is generated and recorded on the public chain.

[0038] Specifically, public chains are used to record open and transparent data, such as power system operation logs, public electricity consumption statistics, etc. These data are visible to everyone and help improve system transparency. Private chains are used to store sensitive data, such as user power consumption data, equipment maintenance records, etc. Only authorized users (such as power company internal personnel or specific regulatory agencies) can access them.

[0039] Use smart contracts to manage access rights to data on private chains. For example, a smart contract can stipulate that only authorized devices can upload data to a private chain, or that only specific users can view sensitive data. Data interaction between public and private chains is achieved through smart contracts. Smart contracts can define rules, such as recording a summary of data on a public chain, while the actual data is stored on a private chain.

[0040] Divide sensitive data into multiple parts and store them in different places. This way, even if a piece of data is leaked, the attacker cannot obtain the complete sensitive data. Use a sharding algorithm to split the data and then save these fragments in different storage locations. Redundant storage strategies can be used to ensure the integrity and availability of data. Encrypt the data using symmetric or asymmetric encryption algorithms. Only authorized users with decryption keys can decrypt the data. Record the hash value of the data on the public chain. The hash value can be used to verify the integrity and consistency of the data without exposing the specific content of the data. When access to the complete data is required, the authorized user reassembles the data with the decryption key and the data fragments.

[0041] Build a user access mechanism, determine user access rights based on the user access mechanism and control user operations after receiving user access requests.

[0042] As a preferred implementation, the user access mechanism includes: determining the role settings in the blockchain network and assigning first-level task permissions to each role; wherein the roles include but are not limited to administrators, operation and maintenance personnel, and data analysts;

[0043] When a user registers, he / she submits a pair of asymmetric public keys and digital signatures and fills in the application information as required. The administrator reviews the application information and, if it meets the requirements, determines the user role and grants secondary operation permissions. The encrypted application information, public key and digital signature are published on the blockchain network based on consensus. If the administrator does not grant secondary operation permissions, the default value of the user's secondary operation permissions is determined based on the region where the user's IP address is located.

[0044] Specifically, the secondary operation authority is the operation authority for the private chain where the data of different area groups are located.

[0045] Specifically, when reviewing the registration application of a user terminal, it includes checking the application information and credit score of the reviewed user. The application information includes the applicant's ID information, name information, and behavioral trajectory information. The credit score includes the reported record. Applications with false or incorrect information or credit scores that have been reported for more than two consecutive times will not be approved.

[0046] As a preferred implementation, the process of determining the user access rights and controlling the user operation based on the user access mechanism after receiving the user access request includes:

[0047] The data management node receives the account login request sent by the user terminal, and performs login account verification after executing the first smart contract in the blockchain subnet. If the verification passes, an operation request is sent to the blockchain main network. If the verification fails, a login rejection instruction is sent to the user; and the operation request is verified to meet the user's secondary operation authority.

[0048] As a preferred implementation, a smart contract is generated through a smart contract module; the smart contract runs through the entire smart grid, and the legal regulations of the electricity market are written into the smart contract as a criterion for determining whether each operation and data access process in the smart grid is in breach of contract; if a breach of contract operation occurs, access is automatically denied and a breach of contract report is generated, which includes the corresponding user unique identifier.

[0049] The above are only preferred specific implementations of the present application, but the protection scope of the present application is not limited thereto. Any changes or substitutions that can be easily thought of by a person skilled in the art within the technical scope disclosed in the present application should be included in the protection scope of the present application. Therefore, the protection scope of the present application should be based on the protection scope of the claims.
