1. A blockchain-based green power certification method, comprising:
pre-processing obtained basic data to obtain structured data and unstructured data, wherein the structured data comprises associated data that maps an entity identifier of a device related to renewable energy into business data of a power business system, and the unstructured data comprises announcement-associated data and electronic contract-associated data in a power business;
performing a proof-of-existence operation for the structured data and the unstructured data on a certification chain to obtain proof-of-existence data, and controlling the certification chain to periodically send the proof-of-existence data to a token chain through multi-chain interaction, wherein the certification chain is a blockchain used to achieve green power attribute certification and certificate issuance, and the token chain is a blockchain used to achieve green power consumption evaluation and consumption label issuance, the multi-chain interaction is to register an identifier for each blockchain, such that each blockchain has a unique blockchain identifier, and data interaction is performed between blockchains based on their own blockchain identifiers;
controlling the certification chain to call a green power certification model and the proof-of-existence data to obtain constraints of the green power certification model, determining, based on the constraints and the proof-of-existence data, whether an attribute of electric energy generated by a power station is a green power attribute, and if the attribute of the electric energy generated by the power station is the green power attribute, generating a green power attribute certificate by using the certification chain, wherein the constraints comprise a first constraint, a second constraint, and a third constraint, the first constraint is a constraint generated based on a planned power generation curve of the power station and a predicted power consumption curve of a power user, the second constraint is a condition for determining whether an on-grid electricity quantity is greater than a settled electricity quantity, and the third constraint is a condition for determining whether the settled electricity quantity is a difference between electricity quantities of a smart electricity meter within power consumption time;
controlling the token chain to call a consumption evaluation model and the proof-of-existence data to determine whether the power user on a power consumption side performs green power consumption, and if the power user on the power consumption side performs the green power consumption, generating a green power consumption label by using the token chain, wherein the consumption evaluation model is an evaluation model generated based on a user environment evaluation parameter and a green power consumption evaluation parameter on the power consumption side, the user environment evaluation parameter is a green rating of a power consumption enterprise or individual, and the green power consumption evaluation parameter is a proportion of green power consumption of the enterprise;
generating a unique digital identifier for the green power attribute certificate and the green power consumption label separately based on a non-fungible token (NFT); and
in a green power attribute certification process of the certification chain and in a green power consumption certification process of the token chain, supervising and verifying, by using a chain of custody, execution information of each node in the certification processes of the certification chain and the token chain; and storing the unique digital identifier in the token chain if the execution information passes the supervision and verification, or storing abnormal associated data in the chain of custody if the execution information does not pass the supervision and verification, wherein the chain of custody performs data interaction with the certification chain and the token chain through the multi-chain interaction in a supervision and verification process, and the execution information comprises operation status information of each node, execution status information of a consensus algorithm, and execution status information of a smart contract;
wherein the business data of the power business system comprises power generation curves, on-grid electricity quantities, settled electricity quantities, ledgers and locations;
wherein the method further comprises:
storing supervision data obtained in the supervision and verification process in the chain of custody, wherein
the storing abnormal associated data in the chain of custody if the execution information does not pass the supervision and verification comprises:
if the execution information does not pass the supervision and verification, controlling the chain of custody to obtain data in the certification process through the multi-chain interaction, processing abnormal data to obtain the abnormal associated data, and storing the abnormal associated data in the chain of custody, wherein the abnormal associated data comprises abnormality pre-warning and prediction data.
