Cyber-Physical Vulnerability Analysis


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.
