Abstract
In the traditional droop control, the VSG algorithm and the voltage compensation link are added to make the inverter have the large inertia characteristic of the synchronous generator (SG). The output voltage of each parallel inverter is the same, and the active and reactive power are distributed according to the rated capacity ratio. Through the design of the voltage current control loop, the equivalent output impedance of the inverter is inductive, so as to meet the droop control requirements. It is proved that the parallel inverter has good dynamic and static characteristics. Matlab/Simulink simulation and experiment verify the feasibility of the proposed control strategy.
