Optimal Energy Management Strategy for Diesel-Methanol Dual-Fuel Powered All-Electric Ship
Nowadays, more green alternative fuels are introduced into shipboard microgrids to reduce emissions and improve energy efficiency. In this paper, an energy optimization framework is proposed for a hybrid-powered all-electric ship (AES) using a dual-fuel generator and energy storage system (ESS). First, the topology of the AES with dual-fuel generators is analyzed. Second, a power scheduling model is developed to minimize operational costs, considering the specific fuel oil consumption (SFOC) of the dual-fuel engine. Finally, several cases are carried out, highlighting both the economic and environmental benefits of this strategy, as well as the importance of integrating a dual-fuel generator in the AES framework.
