The invention relates to the technical field of energy management, in particular to an energy management technology aiming at a marine direct current hybrid power system, and particularly relates to an energy management method aiming at the marine direct current hybrid power system composed of multiple groups of fuel cells, multiple groups of lithium batteries and a super capacitor. By monitoring information such as bus voltage and residual electric quantity of each power supply, each power supply DC/DC converter in the marine direct-current hybrid power system is controlled, so that the hybrid power system is switched among 11 working modes, flow of energy in the hybrid power supply is timely allocated, the stability of the direct-current bus is ensured, and the service life of the hybrid power supply is prolonged. The hybrid power supply system rapidly tracks load changes, and stable and reliable operation of the whole DC hybrid power system is realized.

    本发明涉及能量管理技术领域,尤其是针对船用直流混合电力系统的能量管理技术,具体的说是一种针对由多组燃料电池、多组锂电池及超级电容构成的船用直流混合电力系统的能量管理方法。本发明通过监测母线电压、各电源剩余电量等信息,对船用直流混合电力系统中各电源DC/DC变换器进行控制,使得混合电力系统在11种工作模式之间切换,适时调配能量在混合电源中的流动,在保证直流母线稳定的同时,使混合电源系统快速跟踪负载变化,实现整个直流混合电力系统的稳定可靠运行。
