基于信誉共识的配电自动化系统区块链激励方法

Blockchain Incentive Method for Distribution Automation System Based on Reputation Consensus

配电自动化系统中配置区块链系统对于配电数据的可信存证和共享具有重要意义,然而对应区块链激励机制设计仍不完善。文章在联盟链的基础上,设计一种适用于配电自动化系统数据存储的激励机制。首先,设计节点信誉值评估及动态调整算法,算法中节点凭借在区块链中参与交易的质量、积极性等历史参数获得信誉值。然后,利用信誉值对节点进行奖惩,从而提高节点提交交易数据的质量,达到激励的目的。最后,对模拟电网数据进行实验,结果显示与无激励层的传统联盟链共识算法相比,所提激励算法可以提高节点参与计算的活跃度和达成共识的效率。

The blockchain in distribution automation system is of great significance for the credible storage and sharing of distribution data, however, the corresponding incentive mechanism design is still incomplete. This research is based on the alliance chain and designs an incentive mechanism suitable for data storage in distribution automation system. This paper designs a node reputation value evaluation and dynamic adjustment algorithm. In the algorithm, the node obtains the reputation value by virtue of historical parameters such as the quality and enthusiasm of participating in the transaction in the blockchain. The alliance chain then uses the reputation value to reward and punish the nodes,thereby improving the quality of the transaction data submitted by the nodes and achieving the purpose of incentives.Finally, experiments are conducted on simulated grid data. The results show that compared with the traditional alliance chain consensus algorithm without an incentive layer, the incentive algorithm proposed in this paper can improve the activity of nodes participating in the calculation and the efficiency of reaching consensus.
