Abstract

To solve the problem of response delay in eletrolyzer and fuel cell of wind power coupled with hydrogen system

we proposed a dc-coupled structure system with wind generator

fuel cell

electrolyzer and supercapacitor According to the characteristics of fuel cell

electrolyzer and supercapacitor

we put forward a control strategy of energy management. Based on the proposed control strategy

the fuel cell and electrolyzer can gradually compensate/consume the difference between the power generated by wind turbines and the power required by load. Meanwhile

the supercapacitor can quickly smooth unbalance power caused by the response delay of fuel cell and electrolyzer

and ensure that the power output of hybrid system is consistent with load demand. Matlab/Simulink simulation results verify the effectiveness of the control strategy of hybrid grid-connected system of wind and hydrogen. The proposed control strategy improves the absorption capacity of wind power and reduces the grid connected power fluctuation.
