Distributed Event-Triggered Control for Reactive, Unbalanced, and Harmonic Power Sharing in Islanded AC Microgrids

For several reasons, particularly due to the mismatch in feeder impedance, accurate power sharing islanded microgrids is a challenging task. To get around this problem, distributed event-triggered control strategy proposed article. The suggested technique adaptively regulates virtual impedances at both fundamental positive/negative sequence and harmonic frequencies and, therefore, accurately share reactive, unbalanced, harmonics powers among generation units. method requires no information of impedance involves exchanging units only times, which reduces communication burden without affecting system performance. stability interevent interval are analyzed Finally, experimental results presented validate effectiveness scheme.
