With the large-scale intermittent renewable energy, clean-energy vehicles and energy storage system, the relationship between the huge operation information of distribution network and the control of physical equipment is more and more close, and the distribution network has gradually become a cyber-physical power system (CPPS) with deep interaction of information and Physics. Considering that the distribution network contains a lot of information generation and processing end, the interactive analysis of its information physical system is complex and diverse. The traditional simulation analysis framework of distribution network can not realize the simultaneous operation and operation control under the deep integration of information physical, so it is urgent to build a new simulation platform of distribution network information physical system, In order to achieve more real-time and accurate interaction and calculation between power system and information system. This paper analyses the present situation and progress of the existing distribution network simulation platform, develops the underlying clean-energy generation model based on OPAL-RT, designs the monitoring controller independently, develops the communication network simulation unit of distribution network based on OPNET, develops the high-level operation control unit of distribution network and develops the interface module connecting each unit, A new hybrid simulation platform of distribution network information physical system is built, which integrates power physical system and communication information system.
