Abstract

This paper presents a decoupled and adaptive droop strategy to coordinate parallel operation of inverters. This strategy neatly combines a novel decouple method and an adaptive power sharing strategy. The decouple method guarantees the system stability by defining a pair of virtual power and utilizing a low pass filter to achieve dynamic decoupling. And the adaptive power sharing method is included to achieve accurate power sharing by updating voltage magnitude reference values according to output voltage magnitudes and modified reactive power. The Experimental results are presented to prove the validity and the improvements achieved by the proposed controller.
