基于区块链的电网温室气体排放数据溯源技术

Data Traceability Technology for Grid Greenhouse Gas Emissions Based on Blockchain

针对传统电网温室气体排放数据溯源技术中存在溯源时间长、对电网系统的吞吐量影响大以及溯源可靠性差等问题,提出一种基于区块链的电网温室气体排放数据溯源技术,利用OM法对电力系统的电量边际排放因子进行获取,通过平均值获取实际的温室气体排放量,利用计算出的拟合分数,完成对电网温室气体排放数据的溯源。最后通过该模型,计算排放因子与电网系统时间序列的拟合分数,基于获取的分数完成对数据的溯源,实验结果表明,采用本文方法进行电网温室气体排放数据溯源的溯源时间短,吞吐量影响小且可靠性强。

In view of the problems existing in the traditional power grid greenhouse gas emission data traceability technology,such as long traceability time,great impact on the throughput of the power grid system and poor traceability reliability.A grid greenhouse gas emission data traceability technology based on blockchain is proposed.The OM method is used to obtain the marginal emission factor of power system,and the actual greenhouse gas emission is obtained through the average value.The calculated fitting score is used to trace the greenhouse gas emission data of power grid.Finally,through the model,the fitting score between the emission factor and the time series of the power grid system is calculated,and the data can be traced based on the obtained score.The experimental results show that this method has the advantages of short traceability time,small throughput impact and strong reliability.
