With the development of intelligent distribution network construction and transformation, the traditional distribution network has gradually evolved into a closely related integration system composed of electric power physical network, information communication network and information control network, which has typical characteristics of Cyber-Physical System (CPS). This paper studies the the overall architecture and Information-Physical coupling characteristics of CPS in distribution network, constructs a CPS simulation framework consisting of RT-LAB, OPNET and control platform, and proposes a method of joint modeling and risk simulation analysis of distribution network considering network attack based on CPS. Finally, an example is given to verify the rationality of the platform and the effectiveness of the simulation method.
