Cyber System Physicalizing Modeling and Analysis Method in Cyber-physical Power Systems
摘要
Abstract
In this paper,the information flow modeling,calculation and analysis methodology by physicalizing the cyber in a cyber-physical power system(CPPS)are proposed.The information flow is characterized with a continuous time function by defining network operation parameters as inflow cumulative function,information flow rate,and time delay.After traversal searching out the information flow paths,the formation of information flow rate matrix is established.Then,the matrix elements are assigned by using the improved network calculus method.And the delay upper bound can be explicitly solved considering source models as cumulative functions.Finally,the proposed methodology is applied to calculate the time delay in the intelligent substation automation system.By comparing with the OPNET simulation results,the effectiveness of the proposed model is verified.It can also provide quantitative indication to effectively improve the information flow distribution in substation networking design.关键词
