Power grid credit evaluation and calculation model simulation based on distributed blockchain technology

为解决电网信用评估体系中数据不真实、数据缺乏共享等问题,文中提出了一种基于分布式区块链技术的电网信用评估与计算模型。首先,构建基于分布式区块链的电网信用评估与计算系统模型,其中利用Shepard插值设计了电力客户信用等级评价体系;然后,利用智能合约实现信用数据与结果的共享;最终,搭建仿真模型对所提系统进行实验论证。结果表明,其能够实现客观、准确的电力用户信用等级评估。并且当数据大小为250 kB时,延迟时间与安全性分别为10 ms和87%,优于其他对比模型。

In order to solve the problems of untrue data and lack of data sharing in power grid credit evaluation system,a power grid credit evaluation and calculation model based on distributed blockchain technology is proposed.Firstly,the model of grid credit evaluation and calculation system based on distributed blockchain is constructed,in which the Shepard interpolation is used to design the power customer credit rating evaluation system.Then,smart contract is used to share credit data and results.Finally,a simulation model is built to demonstrate the proposed system.The results show that the proposed system can achieve objective and accurate evaluation of power user credit rating,and when the data size is 250 kB,the delay time and security are 10 ms and 87%respectively,which is better than other comparison models.
