Cyber-Physical Vulnerability Analysis

چکیده
Electrical power systems consists of various components including physical components such as generator, transmission lines, buses, loads, transformers etc. and discrete components such as protection relays and other supervisory and control devices. Cyber failures in discrete components such as protection devices contribute towards cascading failures resulting in blackouts in electrical power transmission systems. These cyber failures can result from a number of ways such as data errors, communication errors, cyber attacks causing software malfunction etc. The technical report aims to model the behavior of these components in nominal and faulty conditions and apply it towards cascade simulation thereby performing contingency analysis and identifying highly vulnerable components in the system for specific combinations of faults. The results are demonstrated using a standard IEEE-14 Bus System.

Modeling and Vulnerability Analysis of Cyber-Physical Power Systems Considering Network Topology and Power Flow Properties
Conventional power systems are developing into cyber-physical power systems (CPPS) with wide applications of communication, computer and control technologies. However, multiple practical cases show that the failure of cyber layers is a major factor leading to blackouts. Therefore, it is necessary to discuss the cascading failure process considering cyber layer failures and analyze the vulnerabi...
متن کاملA Threat-Vulnerability Based Risk Analysis Model for Cyber Physical System Security
The ability to network machinery and devices that are otherwise isolated is highly attractive to industry. This has led to growth in the use of cyber-physical systems (CPSs) with existing infrastructure. However, coupling physical and cyber processes leaves CPSs vulnerable to security attacks. A threat-vulnerability based risk model is developed through a detailed analysis of CPS security attac...

Cyber-physical systems tightly integrate physical processes and information and communication technologies. As today’s critical infrastructures, e.g., the power grid or water distribution networks, are complex cyber-physical systems, ensuring their safety and security becomes of paramount importance.Traditional safety analysis methods, such as HAZOP, are ill-suited to assess these systems. Furt...
متن کاملTitle : Resilience Profiling in the Model - Based Design of Cyber - Physical Systems
We consider the potential to use co-modelling and co-simulation in the design of dependably resilient Cyber-Physical Systems (CPSs). The topic of resilience is widely discussed in the public discourse on CPSs, but is rarely well defined. We propose the description of system resilience in terms of a composite profile which may be used as a basis for assessment and trade-off analysis in CPSs. Our...
