Problems solved by technology

[0008] (1) It does not take into account that many electric meter data are collected by power grid companies, lack of third-party certification and for a large number of electric vehicles and other users, the reliability of collection is relatively low
[0009] (2) The method of integrating security domains is not adopted, only basic matching is performed for users, and lack of awareness of security boundaries may cause impacts and impacts on grid stability

Embodiment 1

[0068] Embodiment 1: as figure 1 and figure 2 Shown; A measurement data security protection method, it includes:

[0069] S1: Classify the meters of users, charging piles, and two-way metering users, use the metering data of high-level users as blockchain label nodes alone, and integrate the metering data of low-level users according to the network topology as blockchain label nodes The high-level users refer to: 220kV and above electric energy metering devices for trade settlement, 500kV electric energy metering devices for assessment, or electric energy metering devices for measuring the power generation of generators with a stand-alone capacity of 300MW or above. The low-level users refer to: 10kV-220kV and above electric energy metering devices for trade settlement, 10kV-500kV electric energy metering devices for assessment, measuring the power generation of generators with a single unit capacity below 300MW, and power generation enterprises (stations) Electric energy m...

Embodiment 2

[0114] Example 2, in view of the problems affecting large-scale measurement security and transaction verification in the prior art, we analyzed the relevant factors and proposed some targeted technical means to solve the problems of insufficient data, numerous influencing factors, and interrelated issues. adverse conditions, and gives the following improved security metering and transaction process:

[0115] Such as figure 1 and figure 2 Shown; A measurement data security protection method, it includes:

[0116] S1: Classify the meters of users, charging piles, and two-way metering users, use the metering data of high-level users as blockchain label nodes alone, and integrate the metering data of low-level users according to the network topology as blockchain label nodes ; Step S1 classifies the measurement data in order to reduce the computational complexity of blockchain technology. Only specific large-scale users and large-scale charging pile groups that have a great im...

Abstract

The invention discloses a metering data safety protection method, which includes: classifying users, charging piles, and two-way metering users' meters, using the user's metering data as a block chain label node alone; Pile contracts adopt hierarchical security checks; they are classified according to voltage level, power supply quality requirements and capacity; users are checked using the security domain method; blockchain smart contracts are used for user direct supply and electric vehicle transactions that have passed the security domain evaluation Conduct transactions; measure users, and use blockchain to mark and transport measurement data; use FAHP algorithm to analyze influencing factors, and then evaluate the overall security of the network. The introduction of smart contracts running on the blockchain reduces the trust cost of electricity market transactions and improves the efficiency of clearing and settlement. At the same time, the security domain method is used to verify the network constraints and compliance of contracts, so as to realize the security guarantee and intelligence of measurement and transactions. change.

Description

technical field [0001] The invention relates to the technical field of electric energy meter metering, in particular to a method for safety protection of metering data. Background technique [0002] Blockchain (Block Chain, BC) is a new application model of computer technologies such as distributed data storage, point-to-point transmission, consensus mechanism, and encryption algorithm. The so-called consensus mechanism is a mathematical algorithm to establish trust and obtain rights and interests between different nodes in the blockchain system. [0003] The Security Region (SR) method is a new method developed on the basis of the point-by-point method. It considers the problem from the perspective of the domain and describes the region that can operate safely and stably as a whole. [0004] Metering is one of the basic functions of the grid. Metering is to record the electricity (electric energy) used as the basis for charging, there are high-voltage metering and low-vol...
