A smart grid data aggregation and monitoring method based on alliance chain

Abstract

A smart grid data aggregation and monitoring method based on a consortium chain, including: a smart meter obtains user power multi-dimensional data, signs the multi-dimensional data and publishes it in the consortium chain; Obtain fixed-height block information, calculate indexes separately, and decrypt signcryption from ciphertext to obtain corresponding user power data; through the analysis of aggregated multi-dimensional data, the control center judges users who are suspected of stealing electricity, and publishes the processed data In the alliance chain, it is stored in a non-tamperable and permanent blockchain; grid operators formulate smart contracts for power consumption regulation according to the power consumption of each user; equipment suppliers monitor equipment operation in real time to ensure the normal operation of the grid. The invention can meet various security requirements such as confidentiality and data integrity of power aggregation and monitoring, and has obvious advantages in terms of computing overhead and communication overhead in multi-user, multi-dimensional data, and multi-receiver modes.

Description

technical field [0001] The invention belongs to the blockchain technology in the field of information security, and relates to a mixed signcryption method. Background technique [0002] Due to the gradual maturity of AMI, power companies have begun to use remote methods to monitor and collect meter data in real time. Through real-time regulation of power consumption, the efficiency of distributed power generation and energy storage can be improved and certain economic benefits can be brought. At present, all kinds of smart terminals and smart meters have been widely used in smart grids. Users can conduct two-way interaction with power companies through smart meters, and users can keep abreast of their own electricity consumption and electricity prices. Electricity information to make corresponding power generation and distribution adjustments and real-time pricing. [0003] However, there are still some security risks in the smart grid at present. Internal security risks in...

Problems solved by technology

[0004] Aiming at the above problems, many literatures have given corresponding solutions. Although these solutions have effectively aggregated power data, the collected data and receivers are very single, and the calculation and communication overheads are too large, and it is difficult to achieve a single Accurate feedback of smart meters, there is an urgent need for new means and methods to solve this problem
