description dqqdA converter unit is disclosed which produces an output voltage based on reference signals (u*, u*) that are generated from active and reactive components (P, Q) of the converter's output power. A first reference signal for a reactive component of the output voltage (u*) is set to zero, thus regulating the reactive component of the output voltage to zero. Therefore, only the active component is contributing to the actual output voltage. The reference signal for the active component of the output voltage (u*) is produced based on the active power component (P) with an active power vs. active voltage droop. To synchronize the frequencies of multiple converter units, a reactive power vs. frequency droop can be introduced for each converter unit, regulating the frequency based on changes in the reactive power component (Q) of each converter unit.
