A network attack simulation method and system for power grid cyber-physical system

Abstract

The present invention relates to a network attack simulation method and system for power grid cyber-physical systems. The method includes: a power system simulator performs simulation according to a preset power system event list, and sends the simulation results to the network attack network through the information system simulator. Emulator; establish a simulated attack event in the network attack simulator, and send the simulated attack event to the power system simulator through the information system simulator; the power system simulator updates the power system event list according to the simulated attack event, and according to the power system event The list is simulated; the technical solution provided by the present invention adds a network attack simulation platform under the environment of the cyber-physical system of the power grid, and sets corresponding Attack scale and intensity, observe and verify the impact of network attacks on cyber-physical systems of power grids and the role of protection measures in the event of system instability.

Description

technical field [0001] The invention relates to the field of power system network attack, in particular to a network attack simulation method and system oriented to the cyber-physical system of a power grid. Background technique [0002] The network attack against the power system has the characteristics of strong concealment, long incubation period, and low attack cost. Although it cannot directly damage the primary power equipment, it can achieve an effect similar to a physical attack by weakening or even completely destroying the normal functions of the secondary system. , have a serious impact on system stability, economic operation, and social stability. When the power is running normally, the failure of the secondary equipment will cause measurement loss or error, affecting the dispatcher's accurate perception of the power primary system; when the primary system fails, if the relay protection device, SCADA energy management When the communication network of the second...

AI Technical Summary

Problems solved by technology

Since the power layer and the communication layer show different operating characteristics, the power components and the information components are deeply interconnected, mutually restricting and influencing each other, presenting the complexity of multiple time domains and spaces, so there is a lack of a unified actual modeling method

Due to the modeling differences between the two, currently no single simulation software can characterize both power and communication models
