Enhancing Microgrid Resiliency Against Cyber Vulnerabilities
Venkataramanan, V., Srivastava, A., Hahn, A., Zonouz, S.
Recent cyber attacks on the power grid have been of increasing complexity and sophistication. In order to understand the impact of cyber-attacks on the power system resiliency, it is important to consider an holistic cyber-physical system specially with increasing industrial automation. In this work, device level resilience properties of the various controllers and their impact on the microgrid resiliency is studied. In addition, a cyber-physical resiliency metric considering vulnerabilities, system model, and device level properties is proposed. A use case is presented inspired by the recent Ukraine cyber-attack. The proposed use case demonstrates how a cyber-physical resilience metric can be used to enhance situational awareness of the operator, and enable better control actions to improve resiliency.
