Quantitative Trade-Off in Distributed Secondary Control for Autonomous AC Microgrids
In this paper, we propose to quantify the trade-off between voltage regulation and reactive power sharing in autonomous AC microgrids with distributed secondary control. It is known that voltage regulation and reactive power sharing in droop-controlled autonomous AC microgrids are...
