Kapourchali, "Model For Evaluating the Reliability of Cyber Component in Power Distribution Systems," 2019 North American Power Symposium (NAPS), 2019, pp. 1-6, doi: 10.1109/NAPS46351.2019.9000301.978-1-7281-0407-2https://rda.sliit.lk/handle/123456789/2328The introduction of smart sensors and intelligent electronic devices allow cyber infrastructure to penetrate different levels of power system. Thus, the effective operation of a cyber-physical power system will be affected by cyber network reliability. The focus of this paper is to analyze the reliability of a cyber-physical power system using the concept of three-layered system approach- Power, Communication and Decision. In this work a new method to compute the cyber reliability of the system is proposed by modelling the interdependency between the communication and decision layer. A case study is done using the radial distribution network in the Roy Billinton Test System to show the possible scenarios that should be considered in the reliability evaluation.enModelEvaluatingReliabilityCyber ComponentPower Distribution SystemsArticle10.1109/NAPS46351.2019.9000301
