Abstract :
This paper use both dynamic phasors model and small-signal model to deal with the precise model of droop-controlled parallel inverters. Then the transient response and stability analysis of P-E and Q-ω droop loop are derived. Both the simulation and experimental results show that the droop gains play an important role in the stability of the system, and the stable range of droop gains is analyzed. In addition, an optimal design method of the droop gains is given.
