The electrical power system of an all-electric ship has been modeled in Simulink for the case of a ship
supporting several high power directed energy loads, among which are a Free Electron Laser (FEL), an
Active Denial System (ADS), and a Laser Weapon System (LaWS). Starting from a load centered
approach, and a physical description of the components of the various loads, individual models of each
load plus a combined model for a system supporting simultaneously one instance of all loads have been
developed. Sample case studies are presented corresponding to expected operational scenarios for a US
Navy ship and to potential emergency conditions. The models have been designed to be interactive,
allowing the operator to change key settings dynamically while the simulation is running, thus mimicking
an actual operation of the power system on a ship in real time. A preliminary graphical user interface has
also been developed to demonstrate the ability of these models to be converted into top-level training
tools for Navy personnel supported by a realistic representation of the ship power system
