Abstract
In low-voltage shore power supplies, the inverter are often controlled using a dual-loop control method. The dual-loop control method is power outer-loop and voltage inner-loop control. The power outer loop contains the power calculation module and the droop control module. The droop control is a simulation of the external characteristics of the synchronous generator, where the voltage and frequency values are obtained from the P-f and Q-U droop curves, respectively. Droop control does not require communication and coordination between devices and is simple and reliable. In this paper, we improve the droop control to improve the smoothness of the shore power supply and ship's grid connection.
