Early Design of AC/DC Interface Converters and Control System for a MW-Scale MVDC Shipboard Power System

Future MVDC shipboard power systems will be characterized by a progressive employment of power converters. In this paper, starting from a real case-study, the focus is on two AC/DC power conversion stages forming the MVDC bus of a shipboard power system. A preliminary design of the AC/DC power conversion stages and their control system is provided in order to verify feasible operations. A coordination strategy based on the droop control technique is adopted achieving load power sharing. Simulation results verify proper operation also in case of pulsating loads.
