I presented our paper “Improving performance of droop-controlled microgrids through distributed PI-control” at the first day of this year’s ACC in Boston. My talk, for which the slides are available here, received the Best presentation in session award.
In this paper, we discuss different types of controllers for for frequency regulation in inverter-based microgrids. We show that a distributed PI controller, which has been previously proposed by my co-authors Martin and John, has the potential to improve the grid’s performance, compared to standard droop control. As in my previous work, we consider performance in terms of resistive power losses incurred in regulating frequency under persistent disturbances.
