Although distributed control in microgrids is well known for reliability and scalability, the absence of a global monitoring entity makes it highly vulnerable to cyber attacks. Considering that the detection of cyber attacks becomes fairly easy for distributed observers, a well-planned set of balanced attacks, commonly termed as stealth attack, can always bypass these observers with the control objectives being successfully met. In this letter, a mitigation technique is thus introduced to… Expand
