Simulation of wind-hydrogen complementary power generation system Based on MATLAB/Simulink

As carbon emissions become the focus of the issue, China put forward the “double carbon” goal, wind energy, hydrogen energy and other renewable energy has been vigorously applied. Because of the uncertainty and randomness of wind energy, wind power generation has volatility and intermittency, and its direct integration into the power grid will impact the stability of the power grid. Hydrogen energy can be used as a flexible resource, long-period energy storage and delivery carrier of power system, which can relieve the pressure of high absorption and stable delivery of new power system. Combining wind energy and hydrogen energy to form a wind hydrogen complementary system can be well connected to the grid. In this paper, wind turbine model, basic electrolytic cell model, proton exchange membrane model and compressor hydrogen storage tank model are established respectively in Matlab/Simulink, and finally constitute wind hydrogen complementary power generation system. And through the analysis of the simulation curve, the feasibility of the proposed system is verified.
