Droop coefficient dynamic estimation method and microgrid use the samet

Abstract

The present invention relates to a droop coefficient dynamic estimation method. The method includes steps of executing by a processor: receiving an active power variation and computing a current droop coefficient based thereon; when the current droop coefficient is not equal to the initial value and the active power variation is positive, setting said droop coefficient by subtracting an adjustment amount from the current droop coefficient; and when the current droop coefficient is not equal to the initial value and the active power variation is negative, setting said droop coefficient by adding the adjustment amount to the current droop coefficient.
