Microgrid pq control parameter design
In this paper, an optimal active and reactive power control is developed for a three-phase grid-connected inverter in a microgrid by using an adaptive population-based extremal optimization algorithm (APEO). To enhance the controllabil-ity and flexibility of the IBRs, this paper proposed an adaptive PQ control method with a guaranteed response. . Strategy I has better transients in frequency, output current, and power. Strategy I reaches steady state faster with overshoots and has a tracking error in the reactive power. To enha trategy for microgrid operation. The main theme of th d increasing interests recently.Read More Download PDF
