Abstract: (165 Views) |
Security and maintenance of power systems against high-impact, low-probability events have always been top priorities for power system operators.Nevertheless, in the case of devastating incidents, the functionality of power systems remains significantly disrupted. Cyber and physical attacks are one kind of these incidents.In recent years, there has been an increase in both physical and cyber attacks targeting the power infrastructure.The reliability of the power system may be jeopardized by physical and cyber attacks if effective defenses and countermeasures are not implemented during operation.The resilience of power grids to cyber-physical destructive attacks is a significant concern due to the criticality of power systems.Hence, enhancing the resilience of power grid topology is imperative for preventing potential threats and attacks.The subject matter can be dissected into two separate aspects for the purpose of assessment:
Step 1: Initiating multiple coordinated cyber-physical attackson a given network.
Step 2: Devising strategies for defense against the attacks identified in Step 1.
The utilization of NTO criteria has been proposed as a potential strategy for defending against coordinated attacks of lower magnitude in both the cyber and physical domains, including actions like switching and bus sectionalization. The GAMS software has been employed to conduct case studies on the IEEE 57-BUS system, with the aim of showcasing the impact of coordinated cyber-physical attacks and the validity of the proposed approach.
