| 摘 要： | 为提高燃料电池混合动力系统功率输出的动态特性,并提高其经济性,在基于DC/DC变换器微分平坦控制的基础上提出了基于高效率功率跟随的混合能量管理策略,建立了包括燃料电池、锂电池、DC/DC变换器和负载等部件的数学模型,并进行了仿真实验。研究结果表明:基于微分平坦控制的DC/DC变换器控制方法能够改善系统的动态响应,修正后的电池的荷电状态(SOC)维持且接近期望SOC值;燃料电池的高效率功率跟随控制策略可以实现系统功率的合理分配,使得混合动力系统可以更安全、高效地运行。

| Abstract: | In order to improve the dynamic characteristics of power output of fuel cell hybrid power system and improve its economy, based on the differential flattening control of DC/DC converter, the hybrid energy management strategy based on high efficiency power following is proposed.The mathematical models of fuel cell, lithium battery, DC/DC converter and load are established and simulation test is done.The results show that:the DC/DC converter control method based on differential flattening control can improve the dynamic response of the system, the state of charge of the modified battery is maintained and close to the expected SOC value;the high efficiency power following control strategy of fuel cell can realize the reasonable distribution of system power, and the hybrid power system can operate more safely and efficiently. |
