From the perspective of information physical fusion, considering the relationship among power network, communication network and information network, the power information system model considering the coupling relationship between power network and information network is established. Firstly, a three-layer model framework of power information physical system considering communication transmission factors is proposed. The whole modeling process is divided into three parts: power network, information network and communication channel, which are effectively associated with power network and information network; Then, a mathematical model of power information physical system integration considering multi-layer coupling is proposed; Finally, the power information physical model based on ieee9 bus is used to verify the effectiveness of the proposed modeling method based on power flow calculation and topology analysis.
