Stress testing power systems' systemic resilience against cyber-attacks

Simulation-based stress tests are a well-known tool in the banking sector for assessing the resilience of the financial system and its entities, and it has recently been discussed to transfer the concept to the cyber-security domain of other critical infrastructures. This work proposes a novel stress testing framework to quantify the systemic resilience of power systems against cyber-attacks, considering both entity- and system-level risks. An exemplary realization of the framework that focuses on cyber-attacks using internet-connected distributed energy resources is provided. This realization includes two ready-to-use simulation approaches for quantifying cyber-attacks' potential impact on inter-area-oscillations and voltage-band violations, as well as assessing the effectiveness of…
