Abstract

Aiming at the problem of "abandoned wind" power coupled hydrogen production in wind power generation, this paper proposes a wind-hydrogen coupling system based on a chain distribution strategy. Firstly, a wind-hydrogen coupling topology circuit structure that can characterize the main characteristics of the abandoned wind power and the proton exchange membrane electrolyzer is established. And then, a wind-hydrogen coupling system is built around a modified interleaved buck converter with extended duty cycle. And the same time, a chain power distribution strategy is proposed for the wind-hydrogen coupling system of the multi-stack proton exchange membrane electrolyzer. Finally, it is verified by simulation that the system improves the utilization rate and reliability of abandonment wind, and effectively solves the problem of coupling control and power distribution of water electrolysis for hydrogen production from abandonment wind power.

Key words
