step 1, generating an intelligent contract through an intelligent contract module; the intelligent contract runs through the whole intelligent power grid, and electric power market legal regulations are written into the intelligent contract and serve as a judgment standard for judging whether each operation and data access process in the intelligent power grid violate or not; when any illegal action occurs in related operation related to the recorded data of the master authority block chain, the related operation is automatically refused to access the power data and a default report is generated, and the intelligent contract module records the default report in an intelligent contract database and broadcasts the default report to an intelligent power grid;
step 2, registering and authenticating all power equipment and power users in the smart grid by using a registration and authentication module before data acquisition is realized; the power consumer or the power equipment provides necessary information for the smart grid data management system, and the registration and authentication module allows the power consumer or the power equipment to become a part of the smart grid data management system and issue a unique ID for the power consumer or the power equipment;
step 3, a data acquisition module acquires power data of all power consumers and power equipment in the smart grid;
step 4, the data indexing module indexes the collected power data according to the service types of the smart grid, and divides the power data, all power equipment and power user IDs into data packets with different service types;
step 5, the data processing and consensus module generates different temporary blocks for the data packets with the divided service types by using a plurality of processing and consensus nodes corresponding to different service types, and performs consensus on the consistency of the generated temporary block information;
step 6, the power data is stored in a distributed manner in a block form by the master block chain network, and block information of different service types is generated in parallel;
and 7, the power data application types of the power data application module comprise power consumption charging of power users, power dispatching, power data mining, power equipment fault analysis and intelligent contracts.
3. The smart grid data management method based on the master block chaining technology as claimed in claim 2, wherein the power market legal regulations written in the smart contract in step 1 include: the system comprises an electric power market anti-unfair competition law system, an electric power market anti-monopoly law system, an electric power quality law system, an electric power price law system, an electric power industry structure regulation law system and an electric power sustainable development law system.
4. The smart grid data management method based on the master block chaining technology as claimed in claim 2, wherein in step 4, the data indexing module adds two parameters of a service type and an ID number inside the service type to the classified power data; the service types specifically include: the method comprises the following steps of power consumption charging of power consumers, power scheduling, power data mining, power equipment fault analysis and intelligent contracts.
5. The smart grid data management method based on the master block chaining technology as claimed in claim 2, wherein the step 5 is implemented by: the processing and consensus node desensitizes the power data related to the user identity information and the commercial confidential information to generate a temporary block; when the temporary block is verified and accepted by most processing and consensus nodes in the corresponding service type, indicating that the temporary block is verified successfully; sending a response of successful verification back to the originating node, attaching the intelligent contract script and the timestamp to the temporary block by the processing and identifying node, and recording the temporary block into the master block chain for storage; if the temporary block is not accepted, power data is recollected.
6. The smart grid data management method based on master blockchain technique as claimed in claim 2, wherein the master blockchain network of step 6 comprises a block format, block size information, block header, action counter, block data record, block locking time; the block format has unique identification; the block header comprises a version number, a previous block hash value, a timestamp, a Merkle root value, a random number and a target hash value; the action counter records the total number of violations in the power data reading application process in the block; the block data record comprises the service type corresponding to the block chain and the corresponding power data; the block lock time is the creation time of the block in the master block chain.
7. The smart grid data management method based on the master block chaining technology as claimed in claim 2, wherein the electricity charge of the electricity consumer in step 7 is used for recording the electricity charge of the electricity consumer in a charging period; the electric energy dispatching is used for requesting electric power from the energy center and dispatching the electric energy to customers; the electric power data mining is used for mining the electric power data and applying the electric power data to follow-up research of the intelligent power grid; the power equipment fault analysis is used for recording a power equipment fault report; the intelligent contract is used for recording violation reports of intelligent contracts violated in the intelligent power grid.
