Abstract

Parallel operation control is one of the key techniques for high performance inverters with the features of excellent regulation, modular, high reliability, and redundancy. Through theoretical analysis of multi-inverters parallel operation model, the paper derived the conventional droop control method, the stability limit of this method and its small-signal model. the effect of different parameters on system power sharing is analyzed. The simulation of conventional droop control method with PSCAD software is also implemented. After discussing the limits of conventional droop control method, a novel adaptive droop control method, is proposed, which can improve active power dynamic and reactive power sharing. A small signal model is established and the advantages of the method over conventional droop control are also validated by simulation.
