英文摘要： As information and communication technologies are widely applied in Smart Grid nowadays, power flow, business flow and information flow are tightly converged and form cyber-physical system, which makes a interdependent relationship between virtual cyber space and physical power grid space, and confronts overlaying risk from both cyber space and phyisical space that threaten secure operation of power gird.Firstly, a cyber-physical system model will be established in this project,researches on transmission merchanism from cyber space to physical space are also conducted. Cyberspace security risks that damages three lines of defense and its negative effects towards physical power gird are analysed. Secondly, a stability control model of power grid considering cyberspace risks will be proposed. Lastly, survivability of cyber-physical system under extreme conditions such as cyber war are analysed. By this project research, the bidirectional and interactive cyber-physical system model that combines virtual cyberspace and physical power gird is established.Both the transmission merchanism and propagation path, which is caused by important cyber risks, are discriminated. And a stability control model is propoesd for electric cyber-physical system. In this project, the risk assessment of electric power stability, which is fit for cyber attacks, is finished under cyber war.
