Electrical weapons and combat systems integrated into ships create challengesfor their power systems. The main challenge is operation under high-power ramprate loads, such as rail-guns and radar systems. When operated, these loaddevices may exceed the ships generators in terms of power ramp rate, which maydrive the system to instability. Thus, electric ships require integration ofenergy storage devices in coordination with the power generators to maintainthe power balance between distributed resources and load devices. In order tosupport the generators by using energy storage systems, an energy managementscheme must be deployed to ensure load demand is met. This paper proposes andimplements an energy management scheme based on model predictive control tooptimize the coordination between the energy storage and the power generatorsunder high-power ramp rate conditions. The simulation and experimental resultsvalidate the proposed technique in a reduced scale, notional electric shippower system.
