Abstract

Abstract—This panel presentation will provide perspectives of resiliency as it relates to smart grids. As smart grid technologies are deployed, the interconnected nature of these systems is becoming more prevalent and more complex, and while resilience is expected to be enhanced, the presence of common mode failures will thwart the ability of the smart grid to achieve full levels of resilience. Studying system behavior in the face of failures (e.g., cyber attacks) allows a characterization of the systems’ response to failure scenarios, loss of communications, and other changes in system environment (such as the need for emergent updates and rapid reconfiguration). The impact of such failures on the availability of the system can be assessed and mitigation strategies considered. This panel will consider measures to identify and eliminate common mode failure mechanisms that might be present in the deployment of smart grid systems.
