摘要
燃料电池的缺点是功率输出疲软,对动态功率加载不能及时做出迅速反应,因此可以采用组合动力源的方式改善。我们采用蓄电池作为辅助能源来储存制动回收的能量,而且嵌入具有高功率密度特性的超级电容。为分配好上述三电源混合动力系统中的功率流,本文以庞特里亚金极小值原理作为基础,制定分别以蓄电池和超级电容的荷电状态为状态变量;蓄电池和超级电容输出功率为控制变量;氢气消耗量为目标函数的能量管理策略。本文通过比较基于PMP和功率跟随两种能量管理策略,得出前者的更优性。
The disadvantage of fuel cell is that the power output is weak and can not respond quickly to dynamic power loading,so it can be improved by combined power source.We use batteries as auxiliary energy to store the energy recovered by braking and embed supercapacitors with high power density characteristics.In order to distribute the power flow in the above three-power hybrid power system,based on Pontriagin's minimum principle,this paper takes the charge state of battery and supercapacitor as state variables,the output power of battery and supercapacitor as control variables,and the energy management strategy with hydrogen consumption as objective function.In this paper,by comparing the two energy management strategies based on PMP and power following,the former is better.
