A MILP model for the design optimization of energy systems on a cruise ship

In this paper, an optimization algorithm based on a Mixed-Integer Linear Programming (MILP) solver is proposed to find the optimal design of the energy generation system on a cruise ship. Both environmentally sustainable solutions (e.g., fuel cells and batteries) and traditional systems are considered. The performance of the energy systems is simulated on real load profiles of a cruise ship sailing in the Baltic Sea and taking into account all the operative and physical constraints. Two different objective functions are selected to test the algorithm, i.e. CO2 emissions and costs. In both cases the MILP determined the best technological mix.
