Optimization of topology and energy management in fuel cell cruise ship hybrid power systems
Current research on energy management strategies (EMSs) often neglects the impact of system topology and local control. This study tackles this issue by optimizing the topology of the hybrid power system on the ’FCS Alsterwasser’ cruise ship and enhancing EMS performance using various local controllers. First, the paper outlines the objectives of the research and provides an analysis of the current domestic and international research status. Second, the methods used in this study are introduced, including the topology optimization method and EMS. Subsequently, a model of the hybrid power system is constructed and verified through simulations. Finally, the effectiveness of different strategies is evaluated according to simulation results. Compared with an EMS based solely on a proportional-integral controller, the combination of a state machine and droop controller achieves better results, reducing battery power fluctuations by 86.5% and fuel cell power fluctuations by 16.2%.
