Abstract

Abstract:

To support the achievement of the "carbon peak and carbon neutrality" goals， the optimization of green hydrogen production systems has become an important path to achieving a low-carbon economy. This paper designs a green hydrogen system equipped with compressed air energy storage and proposes an optimization model for capacity configuration between wind-solar fluctuations and energy storage and hydrogen production systems. This paper uses real wind-solar data for 8 760 h to simulate wind-solar fluctuations under different seasons and climate conditions， overcoming the limitations of traditional models that rely on simplified assumptions and idealized data. The results show that after optimization， the system's abandoned electricity is only 2%， and the levelized cost of hydrogen is 19.30 yuan/kg. A typical week's hourly verification is selected to demonstrate the effectiveness and feasibility of the system scheme in actual operation.The research provides theoretical support for the capacity allocation and operation scheduling of this green hydrogen system and offers guidance for related projects.

Key words: wind power generation, photovoltaic power generation, hydrogen energy, compressed air energy storage, capacity configuration, run the schedule
