考虑信用评分机制的电力碳排放交易区块链模型

区块链是一种新兴的共享数据库技术，由于其去中心化、透明性、公平性的特点开始被研究应用到各个领域当中。在传统碳排放交易机制的基础上引入信用评分机制，定义了交易优先权值，进而提出了碳排放交易区块链网络（blockchain-enabled emission trading network， BETN）模型。此模型中结合碳排放交易机制建立了智能合约模型（smart contract，SC），从而实现了碳排放权和货币的自动计量。最后对3家有着不同碳排放权需求的电力企业进行模拟仿真，结果表明：BENT模型可以更好地反映市场参与者的碳排放交易需求，区块链技术能够保障信息的安全存储和交互；引入信用评分机制有利于市场公平公正运行，进一步约束市场参与者，推动实现碳减排的目标。

Research on Model of Blockchain-enabled Power Carbon Emission Trade Considering Credit Scoring Mechanism

Blockchain is an emerging shared database technology. Due to its decentralization， transparency and fairness， it has been researched and applied in various fields. On the basis of the traditional carbon emission trading mechanism， a credit scoring mechanism is introduced to define the transaction priority value （PV）， and then the carbon emission trading blockchain network model （BENT） is proposed. It is worth mentioning that a smart contract model （SC） combined with the carbon emission trading mechanism is established in this model， thus achieving automatic measurement of carbon emission rights and currency. Finally， simulations of three power companies with different carbon emission right requirements show that the BENT model can better reflect the carbon emission trading needs of market participants， and ensure the safe storage and interaction of information through blockchain technology and the scoring mechanism is conducive to fair and equitable operation of the market， further constraining market participants and promoting the goal of achieving carbon emission reduction.
