Claim:
1. A method of controlling a microgrid comprising at least one distributed generator, DG, and arranged for being connected to a power grid, by means of a converter via which the DG is connected in said microgrid, the method comprising: obtaining an indication of a voltage drop in the microgrid; and running the converter in an interstate mode, in response to the obtained indication, in which interstate mode the converter is configured for controlling both at least one current output and a voltage output; wherein the interstate mode comprises dynamically assigning different weights to the controlling of the current output and the controlling of the voltage output in relation to each other, and wherein the obtaining an indication comprises obtaining an indication that the power import to the microgrid from the power grid is below a predetermined threshold, and wherein the converter remains in the interstate mode for a prolonged time or indefinitely.
