A control method to enhance dynamic performance of parallel inverters in islanded microgrid

A new method for the power sharing in parallel inverters is proposed in this paper. The power calculation unit of the conventional droop is improved to obtain fast transient response. The reduction of the circulating current between inverters during system dynamics is one of the advantages of this method. Also, the proposed control method has a good dynamic performance and power sharing. The simulation results are presented to prove the validity and the improvements achieved by the proposed controller.
