Intelligent power grid security data aggregation method and system based on block chain technology

Abstract

The invention discloses an intelligent power grid security data aggregation method and system based on a block chain technology. A credible authority is responsible for managing and distributing secret information of all other entities; a control center is responsible for integrating, processing and analyzing periodic time sequence data of the cell network nodes and providing comprehensive and reliable intelligent services; agateway is responsible for aggregating the data submitted by the user; a sensing nodes are responsible for collecting data in real time and forwarding the data to the control center. The method includes a system initialization stage; a data collection stage; a security data aggregation stage; an accounting node selection stage; a new block generation stage; a block verification stage; and a decision support stage. On the basis of deeply researching and analyzing the existing application achievements of the block chain technology in the field of smart power grid application, the smart power grid security data aggregation method and system based on the block chain technology are realized, and meanwhile, the user privacy is protected and the confidentiality and integrity of communication data are ensured.

Description

technical field [0001] The invention relates to a smart grid security data aggregation method and system based on block chain technology. Background technique [0002] Since the blockchain has the characteristics of decentralized storage, it can be used to solve the centralized data management bottleneck and inaccurate information feedback of traditional smart grid communication systems. Currently, many studies have applied blockchain to smart grids to address the above challenges. Pop et al. propose a decentralized management model for smart grid demand response programs that balances the smart grid supply and demand balance to some extent. Gao et al. proposed a smart grid monitoring model, which realized power consumption monitoring and management without a third-party trusted center, and realized efficient operation of the grid system through smart contracts. Wu et al. proposed a secure data storage and sharing system based on the Smart Grid Alliance blockchain, which s...

AI Technical Summary

Problems solved by technology

However, this scheme only studies one-dimensional data aggregation, and the user's power data is transmitted in groups in plain text, which poses a great security risk

None of the existing smart grid data aggregation systems based on blockchain technology can simultaneously protect user privacy and ensure the confidentiality and integrity of communication data

Therefore, there is a lack of efficient, safe, and highly available smart grid data aggregation methods and systems based on blockchain technology
