Researches on Data Processing and Data Preventing Technologies in the Environment of Big Data in Power System

In this paper, we mainly focus on the problems of the data processing and data security in the environment of the electricity big data systems. Firstly, we focused on the security of big data storage, as well as the big data applications, including the classification, aggregation and data mining demands. We proposed several practicable schemes to the big data applications. After that, we studied on the problem of the privacy prevention in big data processing. In this paper, we analyzed the demands of the big data privacy prevention in smart grid, and also proposed several methods. Based on the previous researches, we put forward the outline of the research hotspots for the data protection.
