This paper summarizes work that addressed issues associated with the integration of various loads on an all-electric navy ship by the Electric Ship Research and Development Consortium (ESRDC) in the last ten years. The loads include ship service loads such as hotel loads, continuous high-power loads such as propulsion, vital high-power loads such as radar, multi-megawatt pulsed loads such as sensors and defensive systems, and very-high power, gigawatt-level, pulsed loads such as electromagnetic rail guns which require energy storage. The integration of energy storage received particular attention due to its vital role and is discussed accordingly. The analyses were conducted through modeling and simulation and complemented by design studies at component and system levels. Typical simulation results representing operational scenarios of various loads and their interaction with the power system are presented.
