摘要： 针对电力信息物理融合系统(GCPS)时滞稳定性建模及分析中,物理模型及信息模型相互孤立的问题,以单机无穷大系统为例,提出了一种面向GCPS系统时滞稳定性分析的整体建模方法。对GCPS系统产生时滞的原因进行分析和讨论,分别建立了单机无穷大系统的信息模型和物理模型,并通过CIM模型及动态链接库作为沟通信息模型和物理模型的桥梁,实现了GCPS系统的整体建模。仿真结果表明,提出的GCPS系统整体建模方法,构建了其信息流与能量流相统一的计算及分析架构,实现了GCPS系统信息层和物理层时滞稳定性的联合仿真。

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
