基于关联特性矩阵的电网信息物理系统耦合建模方法
Modeling Method for Coupling Relations in Cyber Physical Power Systems Based on Correlation Characteristic Matrix
摘要
Abstract
Since the information layer and the physical layer in the cyber physical power system(CPPS)are closely coupled,the failure of cyber or physical system will seriously affect the normal operation of power system.This paper proposes a correlation characteristic matrix based modeling method for the coupling system to comb and quantify the complex interaction mechanism of information flow and energy flow in the control applications of power system.In this method,the basic analysis unit of CPPS is abstracted from the actual power system applications.Then,the external characteristics of the information nodes, secondary device nodes and communication nodes are described by the expandable multivariate sets.Moreover,the logical association relation and characteristics of physical layer,secondary device layer,communication layer,and information layer are quantitatively described by the correlation characteristic matrix method.Therefore,a complete CPPS model is formed. Finally,an actual power system based on the proposed CPPS model is analyzed,and the usage of the model is illustrated.The results have verified the rationality and effectiveness of the proposed model.关键词
