    摘 要:针对目前电力交易模式下新能源的安全消纳问题,以区块链为核心,提出一种面向 P2P 交易的分级电价方法,充分利用区块链透明、不可篡改、去中心化的特征支撑 P2P 交易数据安全和 P2P 交易电能质量安全。依靠 Merkle 树的特殊结构简化交易数据验证过程,保证交易数据的不可篡改;综合考虑用户侧和供电侧的可靠性要求,构建电能质量分级评价体系,获得各供电节点电能质量评价值,再依据电能质量评价值修正各供电节点上网电价交易的电能质量安全;通过算例验证了该方法可以在有效保证电能质量的前提下提升新能源的消纳。

    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.
    Key words: electricity trading; blockchain; electricity price; fuzzy proximity
