燃料电池集成供电系统的能量管理策略

Energy Management Strategy of Fuel Cell Integrated Power Supply System

针对燃料电池挂网运行时动态响应慢、输出电压随功率增大而快速下降、冷启动困难等缺点,提出一种基于燃料电池功率软特性的能量管理策略,有效解决了燃料电池功率特性软的问题,实现了系统功率的合理优化分配。建立了燃料电池集成供电系统的试验平台,试验结果验证了能量管理策略的有效性。

Aiming at the disadvantages of slow dynamic response,fast drop of voltage with the increase of output power,and difficulty in cold start-up,an energy management strategy based on the soft power characteristics of fuel cells is proposed in this paper,which effectively solves the problem of soft power characteristics of fuel cells and realizes the reasonable optimal power distribution of the system.The experimental platform of fuel cell integrated power supply system is established,and the experimental results verify the effectiveness of energy management strategy.
