Research on data aggregation and user query privacy protection in smart grid
智能电网中数据聚合与用户查询隐私保护研究

摘要

近年来，随着电力行业的飞速发展，智能电网企业的核心业务和支柱技术得到了越来越多的关注。由于各种原因，电力行业与互联网融合后产生了大量数据。在大数据时代，如何对海量数据进行有效挖掘、高效处理与管理成为各国关注的重点。随着信息技术与能源互联网的发展应用使大量信息集中在一起形成海量数据，这些数据需要经过挖掘、清洗、分析得到有效应用。然而，由于传统数据管理方式对隐私保护不够重视和专业知识不足等问题导致在互联网时代中，隐私问题突出，其危害十分严重。由于用户或系统对自身信息的依赖程度非常高，即使在互联网时代人们也不愿意让自己的隐私遭受到损害。本文以配电自动化系统为例研究了智能电网中用户查询隐私保护问题研究及其实施方案。

Abstract

In recent years, with the rapid development of the power industry, the core business and Pillar Technology of Smart Grid Enterprises has received more and more attention. For a variety of reasons, the power industry and the Internet after the integration of a large number of data. In the era of big data, how to effectively mine, efficiently process and manage the massive data has become the focus of attention. With the development and application of information technology and Energy Internet, a large amount of information is gathered together to form a mass of data, which needs to be mined, cleaned and analyzed to be effectively applied. However, due to the lack of attention to privacy protection and the lack of professional knowledge in traditional data management, the problem of privacy becomes more and more serious in the internet age. Because users or systems rely so heavily on their own information, even in the internet age people are reluctant to compromise their privacy. This paper takes distribution automation system as an example to study the research and implementation of user query privacy protection in smart grid.
