  This work proposes an optimal power management strategy for shipboard
microgrids equipped with diesel generators and a battery energy storage system.
The optimization provides both the unit commitment and the optimal power
dispatch of all the resources, in order to ensure reliable power supply at
minimum cost and with minimum environmental impact. The optimization is
performed solving a mixed integer linear programming problem, where the
constraints are defined according to the operational limits of the resources
when a contingency occurs. The algorithm is tested on a notional all-electric
ship where the ship's electrical load is generated through a Markov chain,
modeled on real measurement data. The results show that the proposed power
management strategy successfully maximizes fuel saving while ensuring blackout
prevention capability.
