Theoretical and Experimental Verification of Wind Powered Hydrogen Storage Energy System

Abstract

After analyzing the operating characteristics of the wind energy conversion system (WECS) and the data of wind resources, it was found that in some cases the power grid could not completely consume the power generated by power generation system during the strong wind periods, hence the measures were approached to evaluate the wind power surplus generation, resulting in a waste of wind energy. To solve this problem, a hydrogen production system was added to the wind energy conversion system, and the electricity which the grid cannot absorb was used to electrolyze water and produce hydrogen avoiding the wasting of wind energy. Through the analysis of wind energy conversion system, the hydrogen production system along with the other required components, was developed into the corresponding simulation model built in Matlab/Simulink environment, fully based on the operating principles of the real hardware. Taking power generation and power consumption as the core numbers, the various parts of the system were connected with each other to form a systematic model for simulating a hydrogen production rate of integrated wind powered hydrogen storage energy system. With this simulation model, using different wind data and alternating grid loads, the hydrogen production rate and wind energy utilization rate of the system were obtained. The results show that the interaction of hydrogen production system may increase the utilization rate of wind energy and avoid its wasting. Meanwhile, the hydrogen produced by the hydrogen production system has also many uses as a clean energy source.
