Abstract Considering that the impact of fast frequent start and stop of the shipboard electric bow thruster on the fuel efficiency and system stability in the shipboard microgrid, this paper proposes to add the battery storage in the DC bus of the bow thruster diver and supply for the driver of the bow thruster. The scheme can effectively reduce the capacity of diesel generators, improve fuel consumption efficiency, and reduce the disturbance of the voltage and frequency of the shipboard power system. At the same time, because the bow thruster can operate as a generator when braking, the battery storage can replace the consumption resistance and absorb the energy generated by the fast braking machine. An adaptive PI controller for the voltage loop is designed for three phase interleaved DC-DC converter to increase the load capacity of the converter. And this paper analyzes the selection range of controller parameters. Simulation results show that the controller can effectively suppress the voltage swell and sag of DC bus during the frequent start-up process of the bow thruster.
