| 摘 要： | 智能电网的边缘终端设备会产生大量的时序数据,该数据对电网的智能化运营具有重要意义。为保护数据的隐私性、降低对传输带宽和时延的要求,数据往往需要本地化存储。由于电气设备的规律性,使得产生的时序数据具有很大的冗余性,这为边缘设备数据存储面临的挑战提供了解决方案。本文提出了一种基于动态时间规整的数据去重方法,该方法通过计算数据之间的相似性,从而消除数据冗余、达到数据去重的目的。最后,基于智能电网的真实采样数据对所提出的数据去重技术在边缘计算安全防护系统中的效果进行了分析验证。

| Abstract: | The edge terminals of smart grid always generate a large amount of time series data,which is of great significance to the intelligent operation of smart grid.In order to protect the privacy of data and reduce the requirement of transmission bandwidth and delay,the data often needs to be stored locally.Due to the regularity of electrical equipment,the generated time series data has great redundancy,which provides a solution to the challenge of data storage at edge equipment.In this paper,an edge electricity data deduplication method is proposed based on dynamic time warping,which calculates the similarity between data to eliminate data redundancy and achieve the purpose of data deduplication.Finally,based on the real-world time series data of smart grid,the effectiveness of the proposed data deduplication method in edge computing security protection system is analyzed and verified. |
