Embodiment Construction

[0040] specific implementation plan

[0041] In order to make the object, technical solution and advantages of the present invention clearer, the implementation manner of the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0042] 101: Smart Grid Security Architecture Design

[0043] The method is a smart grid safety hidden danger detection technology based on electrical node intermediateness and support vector machine, and can be used for security protection of complex smart grid cyber-physical systems. figure 1 It is an architecture diagram of security protection, which consists of two parts. The first stage is to assess potential safety hazards, and the second stage is to detect security vulnerabilities. Through the safety risk assessment of each control loop of the smart grid, in the control loop with high security risk, the designed security module can immediately verify whether the working state of the loop is ...

Abstract

The invention relates to an intelligent power grid safety protection method. Depending on characteristics of an intelligent power grid itself, an electric node intermediateness assessment module is designed to screen out local loops relatively high in safety risk in the intelligent power grid; combined with the expandability of the intelligent power grid, only a support vector machine module needs to be embedded into a local control loop of the intelligent power grid so as to realize the training on an intelligent power grid normal work behavior model; working parameters of the intelligent power grid can be easily extracted, arguments can be provided to normal behaviors / attract behaviors of the intelligent power grid, and the source of safety holes can be tracked; the safety module is embedded into the existing control loop, the safety of the power grid can be monitored in real time, and the usability and the integrity of the power grid are ensured; in addition, the introduction of the safety module is relatively good in security, the safety is not liable to be spied or removed, the increased additional area and power consumption are respectively small, and the normal functions and the operation speed of the intelligent power grid are not influenced. The method provided by the invention is compatible with existing power grid safety protection methods and can be combined with other protection methods.

Description

technical field [0001] The invention relates to the field of information physical security of smart grids, that is, a security protection method for smart grids. Specifically, it is a method for implementing safety hidden danger assessment and safety loophole detection of smart grid by applying electrical node betweenness and support vector machine. Background technique [0002] The number of smart grid users is large, the two-way communication and interaction are strong, and the network boundary extends to the power generation side and the user side to cover all links of the smart grid. more prominent. There are risks such as illegal theft and tampering of production information during network transmission, damage to the integrity, confidentiality, and availability of business systems, and illegal use, remote control, and illegal operations of smart devices, smart terminals, and user terminals. Information and communication technology is one of the fastest-innovating, mos...
