Abstract

Abstract: According to the separation problems of physical and cyber modeling in time delay stability analysis for grid cyber-physical system (GCPS), an integrated modeling method is presented and proved by single machine infinite bus system (SMIBS). The time delay and stability of GCPS are analyzed and discussed, and the physical and cyber models of SMIBS are established respectively. The dynamic linking library by EA and VS based on information model (CIM) are generated, and the united simulation platform is achieved by MATLAB. The results of the simulation show that the unified structure of information flow and physical flow for calculation and analysis in GCPS is implemented by the integrated modeling method, and the co-simulation for the time delay and stability analysis including information layer and physical layer is realized.

Key words: grid cyber physical system, single machine infinite bus system, time delay stability, integrated modeling
