چکیده مقاله

This paper presents a novel control strategy for parallel inverters of distributed generation units in an AC distribution system. The proposed control technique based on instantaneous average current sharing control scheme (IACS) ‚ uses adaptive fuzzy controllers to adjust the gains. This adaptive fuzzy gain scheduling is introduced to the IACS controller to improve the current and power sharing for a condition where the line impedance is different among the inverters. Simulation results are presented to show the effectiveness of the adaptive fuzzy gain-scheduling in improving the load sharing among parallelconnected inverters, where the line impedance is different among them.
