    摘要:

    传统微电网电力交易模式存在中心化、数据不透明等问题, 区块链的去中心化、不可篡改、可追溯和无需信任等特点被广泛用于电力交易. 当前的研究主要在共识机制、交易机制和隐私保护方面, 且大多都需要交易者每周期不断进行报价. 本文提出了一种基于权威证明(Proof of Authority, PoA)共识的联盟链无报价电力交易机制, 电力消费者无需报价只需预存电费, 即可在电费耗尽前基于智能合约自动进行电力交易, 资金的结算采用能源代币. 最后与其它4种现有区块链电力交易方案进行对比分析, 并模拟仿真了5个产消者和5个消费者的电力交易, 分析了买卖双方的收益. 结果表明本方案让买卖双方同时受益, 经济成本更低, 共识效率高.

    Abstract:

    The traditional microgrid electricity transaction mode has such problems as centralization and data transparency, and because of the features like decentralized, tamperability, traceability and untrusted characteristics of the Blockchain is widely used in electricity transaction. Current research focuses on consensus mechanism, trading mechanisms and privacy protection, and most of them require traders to make constant bidding every cycle. This paper presents a consortium Blockchain without bidding electricity trading mechanism based on the consensus of proof of authority (PoA), electricity consumers do not need to bid the pre-deposit of electricity, can automatically trade electricity based on smart contracts before the electricity bill runs out, the settlement of funds using energy tokens. Finally, the comparison and analysis of the other 4 existing Blockchain electricity trading schemes, and the simulation of 5 producers and 5 consumers of electricity transactions, analysis of the buyer’s and and seller’s earnings. The results show that the scheme benefits both buyers and sellers at the same time, with lower economic costs and high consensus efficiency.
