Design And Implementation Of Simulation Testbed For Power Grid

As an important national infrastructure,the power grid not only provides energy for industry and manufacturing,but also is closely related to people's lives and national security.The good operation of the power grid can guarantee the country's rapid development,and the safety technology of the power grid is in the important research field of scientific research.With the continuous application of information and communication technology in the power grid,while the grid system is becoming intelligent,it is also facing more and more network threats.How to effectively improve the security and defense capabilities of the power grid becomes crucial.The simulation test bed for the power grid is an emerging network security experiment platform.It is of great significance to continuously improve the network security of the power grid by simulating the power grid software and constructing an experimental system in which network attacks and analysis can be carried out.This paper designs and develops a simulation test bed for the power grid.The logic architecture of the test bed is divided into three parts: power grid simulation,control center and network communication.The three parts are developed through software and integrated to form a power grid that can finally be used for network attack experiments.The test platform,where the network attacks implemented mainly include: denial of service attacks,malicious command attacks that bypass the security protection layer,and coordinated attacks that combine the two,and briefly describe how to defend against these three types of attacks and how to use machine learning and other technologies Conduct data development.The main research content of this article includes the following aspects:(1)Develop a power grid model through software simulation to build a common 14-bus dynamic power grid.The power grid and the control center communicate and connect through the network.Discusses different technical methods of power grid simulation,such as the combination of hardware,software,and hardware,and discusses and analyzes its advantages and disadvantages.(2)The construction of the network in the grid test bed.The real power grid contains several network nodes to transmit instructions,and the corresponding network nodes need to be simulated on the test platform.This paper uses software simulation to communicate between the control center and the simulated power grid,and between the attacker and the power grid.Communication,where an attacker sends instructions to affect the normal operation of the power grid,such as a denial of service attack.(3)The three main components of the fusion control center,simulated power grid and network communication constitute the power grid simulation test bed,which is used to analyze the impact of network attacks,put forward defensive measures and conduct relevant data development.(4)Conduct network attack experiments,mainly to implement three common network attack experiments.By analyzing the impact of the network and power grid operation after the attack,put forward corresponding defense measures and how to use simulated data for development and utilization.Through the above design and development work,the simulation test bed system for the power grid has been realized,which has the advantages of low cost,flexible architecture and difficult network security technology research to solve the real physical world.Experiments show that this system is suitable for power network security research It helps to improve the safety of the actual power grid network and has practical value.
