The design and control of electric warship power systems is a complex, challenging problem and numerous power system architectures, technologies, algorithms, and control schemes have been proposed. Instead of a quantitative assessment of these ideas based on ideal, steady-state conditions, a set of representative operational vignettes that span the entire electric warship mission package is introduced in order to obtain true results. This paper describes a set of realistic test cases that provide load demand dynamics based on a variety of unique scenarios, mission load characteristics, and human-in-the-loop decision-making. Stochastic and deterministic power profiles are established for individual ship systems and mission loads, which are then combined together for a particular scenario. These test cases can be applied to early-stage design trade studies as well as design tool development. For example, various control methods can be benchmarked against the same test cases. In addition to the established test cases, the method used here enables operators to communicate to design engineers how they intend to use the ship (not the other way around).
