Synchrony in Networked Microgrids Under Attacks

This paper proposes attack-resilient distributed control for synchronization of islanded, networked, inverter-based microgrids. Existing cooperative control techniques are susceptible to attacks and cannot guarantee synchronization. The effect of attacks on sensor/actuator, communication links, and hijacking controllers is studied. A resilient synchronization protocol is presented to address sensors/actuators attacks. Attacks on communication links and adverse effects of hijacking controllers are also mitigated by designing a trust-based control protocol. The efficacy of the proposed solutions is evaluated for a modified IEEE 34-bus feeder system under different types of attack.
