In recent years

with the rapid development of new energy development and utilization

fuel cell canrealizethe effective utilization of hydrogen energy. In view of such disadvantages of fuel battery in the operation in the grid as slow dynamic response

big variation of output voltage with load variation

soft externalfeatureanddifficultsoftstartup

in this paper

a kind of coordination and control strategy for fuel battery integrated power supply is proposed. Firstly

the fuel cell system composition is introduced. Then the existing control strategies are analyzed and a coordinated control strategy is proposed to solve the problem of soft power characteristics of fuel cells. Finally

a simulation model of the integrated power supply system of the fuel cell is built on Matlab/Simulink. It is shown by the result that the strategy can effectively solve the problem of soft power characteristics of the fuel cell

so as to prevent voltage sag and offline shutdown

realize the rational and optimal distribution of system power

and improve stability and reliability of the systempowersupply.
