Optimization of Hybrid Propulsion Systems
1 MI-SE@MALTA, MARSEC-XL Foundation, Senglea, Malta
ABSTRACT: Powertrain hybridization permits the benefits of more than one power source to be integrated and exploited for a beneficial effect on an objective, such as reduction of fuel consumption or emissions. Due to their operating profiles however, marine hybrid vessels do not exhibit much opportunity for free energy re-cuperation. Fuel savings can be realized by bettering component operating points, yet this requires correct siz-ing matched to the expected usage. In this paper, a multi-objective genetic algorithm is used to optimally size propulsion components in order to minimize fuel consumption as well as installation weight for a hybrid mo-toryacht operating on a day cruise scenario.
