| Abstract: |
| The high integration of physical and cyber system is the development tendency of smart distribution network in the future, so the key technologies of reliability assessment for distribution network CPS(Cyber Physical System) are summarized and prospected. Starting with the excavation of physical and cyber system’s risk origins in distribution network, the influence factors are analyzed further, based on which, classification methods and specific mathematical expressions of reliability assessment index for physical and cyber system of distribution network and establish technologies of reliability assessment index for CPS are summarized and then the research progress of reliability assessment algorithms and methods is discussed. Four aspects are prospected for distribution network CPS: heterogeneous data processing, modeling and simulation, reliability assessment index and method, generalized attack and defense mechanisms. |
| Key words: cyber physical system smart distribution network generalized attack reliability assessment defense mechanism |
