Off-grid Wind-Solar Coupled Hydrogen Production System Xuesong Chang, Yingzi Xian, Lei Wang

Abstract

We analyze the structure of the wind-solar coupled hydrogen production system and optimized system architecture through performance comparison. To obtain the optimal architecture, we first compare the DC bus and AC bus systems to acquire an initial optimized system architecture, and secondly, we analyze the centralized and distributed structure of the system and compared them in five aspects: cost, reliability, system efficiency, stability, and control complexity. Finally, we verified the feasibility of the architecture by analyzing and calculating the performance of the system.
