Centralized power generation of the integrated electric propulsion enables various optimization techniques to automatically activate diesel generators to respond the load changes in an optimal manner. In this study, the power generation scheduling problem is formulated with constraints for a large cruise ship. The problem is solved with assistance of SFC modelling by three recent metaheuristic optimization methods, namely grey wolf optimizer, ant lion optimizer and whale optimization algorithm. Simulation results demonstrate the proposed methods ensure minimum fuel consumption compared with baseline data for certain load profiles.
