Design And Experiments Of Distribution Network CPS Simulation Platform

With the deepening of the coupling degree between information flow and energy flow,distribution network is gradually becoming a Cyber Physical Power System(CPPS)in which information and physical depth interact.Some typical information system problems,such as delay,packet loss,congestion,malicious attacks,will lead to more complex fault analysis of power system.The accuracy and real-time of simulation analysis can not be guaranteed by traditional distribution network simulation methods.In the first chapter of this paper,the background and significance of distribution network information physics system simulation technology are analyzed in detail.The current research status of distribution network information physics system simulation technology is summarized,and the ideas and schemes of different simulation technologies are expounded.In the second chapter,the design method of the simulation platform for distribution network information physical system proposed in this paper is discussed in detail.The operation principle and construction mode of the important components such as the bottom control unit,monitoring controller,network simulation unit and system operation control unit are expounded respectively.The key problems including the model establishment of the two simulation parts,signal acquisition and data interaction channel are also discussed.Detailed discussion was made.In the third chapter,the effectiveness and real-time of the simulation results are discussed in detail through the inherent delay and real-time test.In the fourth chapter,a comprehensive simulation example is given to illustrate the effectiveness and rationality of the simulation technology through the typical problems of power hardware-in-the-loop simulation,network communication hardvare-in-the-loop simulation,master station hardware-in-the-loop simulation and distributed power supply collaborative control of distribution network information physical system.The fifth chapter is a summary of the full text,and puts forward more directions for further study.
