基于区块链的电动汽车去中心化交易研究

A decentralized transaction method based on block chain in V2G

随着分布式电源技术和新能源技术快速发展,参与电力交易的电动汽车和新能源发电用户数量不断增多。由于电动汽车和新能源具有随机性和不确定性,现有交易模式无法支撑交易需求。区块链具有去中心化、不可篡改等特点,可以有效解决车网互联系统(vehicle-to-grid,V2G)电力交易遇到的挑战。首先,基于区块链技术,提出基于组合拍卖和滚动撮合交易的交易规则,设计了滚动撮合交易模型。随后,基于组合拍卖和滚动撮合交易机制规则,设计了V2G的电力交易智能合约。最后,为验证所提方案的可行性,将智能合约发布到趣链区块链平台上,进行模拟实验。实验结果表明,本文所提方法能够有效提高交易成功率。

With the rapid development of distributed power and new energy technology,the number of electric vehicles and new energy generation users participating in power trading is increasing.Due to the randomness and uncertainty of electric vehicles and new energy,the existing trading model cannot support the trading demand.Blockchain has the characteristics of decentralization and non-tampering,which can effectively solve the challenges encountered in vehicle-to-grid(V2G)electricity trading.Based on blockchain technology,a transaction rule based on combinatorial auction and rolling aggregation transactions is first proposed and a rolling aggregation transaction model is subsequently designed.Then,based on the rules of the combinatorial auction and rolling aggregation trading mechanism,a smart contract for V2G electricity trading is designed.Finally,in order to verify the feasibility of the scheme,the smart contract is published on the hyperchain blockchain platform allowing simulation experiments.The results show that the scheme proposed in this paper can improve the success rate of the transactions.
