摘要：
On the basis of analysis on paralleled micro-grid multi-inverters power distribution mechanism, the variation of active power and reactive power circulation between inverters with different power levels was proposed and a specific analysis on the impact mechanism of equivalent line impedance to power distribution and limitations of traditional droop control are given. An improved Q-Ėn droop control method with Ėn restoration mechanism was proposed to improve reactive power sharing. Its operation principle and control method were explained and analyzed. Simulation and experimental results show the improved drooping controller makes the paralleled multi-inverters sharing the load power by the ratio of rated capacity accurately. © 2016, Editorial Department of Electric Machines and Control.
