Embodiment Construction

[0031] The present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments.

[0032] like figure 1 As shown, it is an application scenario of a smart grid consistent privacy protection method based on state decomposition provided by the embodiment of the present invention, in which a user cluster can represent a corridor, a building user, etc., using the method of this embodiment The power company only needs to inquire about a certain user to know the overall power consumption situation, and monitor the power grid information in real time, so as to better regulate the power network.

[0033] like figure 2 As shown, the embodiment of the present invention provides a smart grid consistent privacy protection method based on state decomposition. First, it is the preprocessing process of the electricity meter data at the user end. Before information interaction, the user needs to pre-operate his own electricity co...

Abstract

The invention provides an intelligent power grid consistency privacy protection method and system based on state decomposition, and belongs to the field of information transmission and privacy protection. The method mainly comprises the processes of user-side electric meter data preprocessing and data distribution. Firstly, measured intelligent electric meter data are decomposed, one part is used for conducting data transmission with adjacent users, the other part is used for conducting internal calculation, and internal and external weights needed when information is transmitted are generated; in the data distribution process, an improved push-sum algorithm is adopted, a user carries out aggregation operation on data sent by adjacent users, information data of the user is weighted and sent to neighbors, and a final consistent value is achieved. According to the method, on the basis of ensuring that each user obtains an average consistency result, the personal privacy of each user can be protected.

Description

technical field [0001] The invention relates to the fields of information transmission and privacy protection, in particular to a method and system for consistent privacy protection of smart grids based on state decomposition. Background technique [0002] In modern society, people's demand for energy continues to increase. At the same time, with the rapid development of science and technology in our country and the continuous improvement of infrastructure, smart grids built using the latest electronic communication technologies have also emerged as the times require. Through the smart meter in the smart grid, the power supply company can better obtain real-time monitoring information of the user's electricity consumption, so as to better regulate the power network. In order to be able to monitor the information of the power grid in real time, the power company needs to collect a large amount of user information. These user information are often sensitive and will expose the...
