A novel energy management strategy based on minimum internal loss for a Fuel Cell UAV

To reduce the equivalent hydrogen consumption of the system and increase the lifetime of the fuel cell, this paper proposes a two-level energy management strategy (EMS) based on the equivalent Circuit Model of Fuel Cell UAV power system. First, the reduction of the system's equivalent hydrogen consumption is regarded as the basic goal. Then, the internal loss and average operating efficiency are added to the objective function. Finally, the output power of the fuel cell system is controlled by solving the objective function to realize power distribution. A hardware-in-the-loop experimental platform was built to compare the superiority between the proposed EMS and traditional equivalent hydrogen consumption (ECMS). The results indicate that the proposed algorithm reduces the equivalent hydrogen consumption of the system by 4.24% and increases the average operating efficiency of the system by 4.7% separately. It can effectively reduce the internal loss and the equivalent hydrogen consumption of the system and maintain the battery SOC.hese instructions give you basic guidelines for preparing camera-ready papers for conference proceedings.
