Embodiment Construction

[0062] In order to make the purpose, technical solution and advantages of the present invention clearer, the technical solution of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. For the overall flow chart, see the attached figure 1 : A distribution network CPS interdependence system network attack risk assessment method based on the attacker's perspective, characterized in that it includes the following steps:

[0063] Before launching an attack, the attacker must collect information on the target network in order to determine the target and method of the attack and increase the probability of success of the attack, and find out the weak points of the target network that can be exploited to launch the attack. By establishing the structural model of the target cps network, we will prepare for the subsequent analysis of the weak link of the cps-dependent network and th...

Abstract

The invention provides a network attack risk assessment method of a distribution network CPS dependent system based on an attacker perspective. From an attacker perspective, the risk level caused bypower grid cps system attack is analyzed based on different attack and invasion aims and the risk situation of potential attack paths is analyzed, so that the method provides a new perspective for thestudy of cps security analysis and protection methods, and provides an accurate basis for grid operators to formulate defensive measures.

Description

technical field [0001] The invention belongs to the technical field of electric power system automation, and in particular relates to a network attack risk assessment method of a distribution network CPS interdependent system based on the perspective of an attacker. Background technique [0002] With the continuous development of smart grid construction, the continuous promotion of intelligent equipment and the rapid improvement of the automation level of the power system, the data exchange between the dispatch center, power plants and users is becoming more and more frequent, and the interaction mechanism between the power network and the information network is increasingly Complexity poses new challenges to the security, reliability, and real-time performance of power control systems and data networks. Cyber ​​physical system (CPS) is a next-generation power system engineering that realizes the deep integration of computing, communication and control technologies. With th...
