        摘 要:針對目前電力交易模式下新能源的安全消納問題,以區塊鏈為核心,提出一種面向 P2P 交易的分級電價方法,充分利用區塊鏈透明、不可篡改、去中心化的特征支撐 P2P 交易數據安全和 P2P 交易電能質量安全。依靠 Merkle 樹的特殊結構簡化交易數據驗證過程,保證交易數據的不可篡改;綜合考慮用戶側和供電側的可靠性要求,構建電能質量分級評價體系,獲得各供電節點電能質量評價值,再依據電能質量評價值修正各供電節點上網電價交易的電能質量安全;通過算例驗證了該方法可以在有效保證電能質量的前提下提升新能源的消納。

        Abstract: The current electricity trading model has the problem of the safe consumption of new energy. This paper proposed a hierarchical electricity price method for P2P transactions based on the core of blockchain. It used the transparent, immutable, and decentralized features of the blockchain to ensure P2P transaction data security and P2P transaction power quality security.It relied on the unique structure of the Merkle tree to simplify the transaction data verification process and protect the transaction data.This paper considered the reliability requirements of the user side and the power supply side and constructed a system for power quality classification and evaluation. The quality of the electric energy safety could be adjusted following the power quality evaluation value of each power supply node.After example analysis, it is verified that this method could improve the consumption of new energy under the premise of effectively ensuring the power quality.
