Abstract
In this work we propose an adaptive cyber-enabled control scheme for transient stability of smart grids. Based on feedback linearization control theory, the proposed distributed scheme utilizes a distributed energy storage system (ESS) to modify the dynamics of the power system during transients. However, the controller's design parameter is adapted to the cyber state of the smart grid. Specifically, the distributed control scheme adapts to the level of noise, communication latency, interference, and data injection attacks. Further, depending on the severity of the physical disturbance, the controller adjusts its design parameter in order to speed up the stabilization process. The performance of the proposed control scheme is validated on the IEEE 68-bus test power system where the controller is shown to efficiently stabilize the power system during physical and cyber disturbances.
