Research on the Mechanism of Distribution Network CPS Security Impact

The improvement of communication and information technology has greatly enhanced the observability and controllability of distribution network. It is necessary to further study the operation characteristics of distribution network from the perspective of CPS. This paper mainly studies the security impact mechanism of distribution network based on CPS. Firstly, the method of CPS network attack in distribution network is proposed. Secondly, the coupling mechanism and transmission mechanism of risk between information space and power space are studied. Finally, how power system faults react on information space and form information security threat is analyzed, and the mechanism of reverse transmission is simulated. Furthermore, the validity of the model is verified.
