Impact of the voltage dips in shipboard microgrid power systems

Voltage and frequency transient variations are the most common power quality issues in a ship microgrid system. In this paper, the impacts of the voltage dips induced by the sudden-load of ballast pump are analyzed in detail for the ship power systems. Several relevant ship power quality standards and potential solutions are introduced and discussed properly. The experimental tests from a real ship are presented to show the impact of moderate voltage dips on the selected working generator and bow thruster.
