Control Optimization And Design Of Fuel Cell Power Generation System

With the development of the times,more clean and efficient energy will certainly replace the traditional fossil energy.As a kind of clean energy,hydrogen energy is the most promising energy source.Therefore,research on hydrogen fuel cells has very important practical significance.This paper aims at the current status of fuel cell development,selects the fuel cell bus power generation system for research and design,and goes deep into the optimal control of the fuel cell output target.The main contents are as follows:According to the working principle and requirements of the fuel cell power generation system,the overall structure of the fuel cell bus power generation system is designed.Including the various system components that allow the fuel cell to work and the coordinated communication of each system,and finally completed the design of the cloud communication module that uploads fuel cell work information.The control structure of the fuel cell and the hardware design of the mainboard were completed.Considering the need to control the module and receiving too much information,in order to facilitate the information acquisition and algorithm control of the fuel cell power generation system,the control module was distributed in this paper.Architecture control.The use of an ARM chip as the control core of the motherboard is selected,and with peripheral circuits,peripheral modules such as sampling,communication,control output/input,and GPRS communication are redesigned.In order to achieve the dual-objective optimal control of the output power and efficiency of the fuel cell power generation system,an improved differential evolution dual-objective optimization algorithm with a constraint processing mechanism is introduced.The comparison of the output power and the efficiency before and after the optimization of the simulation and comparison algorithm was performed on MATLAB,which verified the control effect of the algorithm in the output of the fuel cell power generation system.Finally,through the construction of hardware platform and software platform,on the 50 KW fuel cell power generation system of Wuhan University of Technology,the supervisory control system of the host computer is used.The actual experimental platform verifies the practicability and effectiveness of the algorithm on the fuel cell system.
