One of the pressing challenges in the distributed EMS field is cybersecurity. Energy system is one of the most critical infrastructures. Its security is of paramount significance to the well-being of the society. Most state-of-the-art distributed EMS algorithms lack security features that can withstand cyber threats, e.g. data integrity attacks. From our interaction with the microgrid operators, we learned that the cybersecurity of the system and the resilience against cyber-attacks are must-have features for the distributed DER controller. The two critical cybersecurity aspects of the distributed microgrid EMS are 1) data integrity; and 2) data confidentiality. Our lab has been investigating these cybersecurity issues since 2012.
