针对船用燃料电池混合能源系统能效问题,结合在相同条件下混合能源输出功率和能量消耗,提出了基于功率解耦的外部能效最大化策略(改进EEMS),使其能够更加高效地运行。在Matlab/Simulink仿真环境下,搭建改进EEMS模型,验证改进EEMS能效提升效果。仿真结果表明,在氢燃料利用率上,改进EEMS比EEMS提升了5.78%;改进EEMS比经典PI控制策略提升了15.61%;改进EEMS比等效优化策略提升了11.09%。因此,改进EEMS策略确实可以提高船舶混合能源系统氢燃料的能效。本文研究成果对于燃料电池在船舶混合动力系统高效运行具有理论意义和应用价值。
In view of the energy efficiency problem of Marine fuel cell hybrid energy system, combined with the hybrid energy output power and energy consumption under the same conditions, the external energy efficiency maximization strategy based on power decoupling (improved EEMS) is proposed to enable it to operate more efficiently. In Matlab/Simulink simulation environment, the improved EEMS model is built to verify the effect of improved EEMS energy efficiency. Combined with the comparison results of power output power and energy consumption under the same conditions, the analysis shows that the improved EEMS improves the hydrogen fuel utilization by 5.78% compared with EEMS, and compared with the classical PI control strategy and equivalent optimization strategy, the improved EEMS improves by 15.61% and 11.09%, respectively. It effectively improves the hydrogen fuel economy of the system, and makes the fuel cell ship hybrid power system operate efficiently.
