Enhancing Microgrid Resiliency Against Cyber Vulnerabilities
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.
