基于区块链和混合连续双向拍卖的分布式电力交易机制

针对分布式电力交易中缺乏有效可靠的交易机制来规范用户信用行为的问题，提出基于区块链和混合连续双向拍卖的电力交易匹配机制。混合连续双向拍卖把信用值引入到用户报价调整中，通过信用值和报价的加权平均值进行连续双向拍卖交易匹配。这种匹配机制能有效减少恶意节点对电力资源分配的影响，从而提高总体收益和用户交易积极性。同时，为了使总体利益最大化，提出基于均衡值的报价策略。然后，借助区块链实现用户间电能数字证明和费用之间的交换。最后，通过分布式电力交易模拟实验证明该交易机制的有效性。

Power trading mechanism based on block chain and hybrid continuous double auction

As there have been no effective and reliable transaction mechanisms to standardize user credibility during distributed electricity transaction, an electricity transaction matching mechanism based on blockchain and mixed continuous double auction were proposed in the paper. Credit value was introduced by the mixed continuous double auction into adjustment to prices offered by users. The continuous double auction transaction matching was done through credit value and the weighted mean of offered prices. This type of matching mechanism works effectively in minimizing the effects of malicious node on electricity resource allocation and improving total revenues as well as the transaction enthusiasm of users. To maximize the total revenues, the pricing strategies based on equilibrium value were proposed, and the transactions between user electricity digital certificate and fees were realized trough blockchain. Finally, the transaction mechanisms were verified to be workable through distributed electricity transaction simulation experiments.
