Abstract

A novel droop control strategy for controlling parallel inverters is proposed in this paper. In this paper, the reactive power versus PCC voltage droop is introduced, and then output reactive power of the inverters is adjusted to be equal. When load is changed greatly in microgrid, the voltage frequency and amplitude deviate from normal values greatly. By adaptively adjusting the droop position of some large capacity inverters, it can share active and reactive power equally among inverters and limit the frequency and voltage amplitude deviations in a certain margin. The analysis and the design procedure are provided explicitly. Simulation and experiment results validate the proposed control strategy.
