Research on the Optimal Planning Method of Wind-Solar Hydrogen Production Park System Considering the Optimal Proportion of Wind and Solar Energy

Implementing wind-solar hydrogen production in areas rich in wind and solar resources can substantially boost the economic viability of park systems and encourage the use of renewable energy. Based on this concept, this study develops a system for a wind-solar hydrogen production park, incorporating energy storage and hydrogen storage mechanisms. Aiming to minimize the system's lifecycle annualized cost, an optimization model is devised, constrained by power balance and equipment output, and solved through mixed-integer linear programming. The optimization results, derived from varying wind and solar output characteristics and hydrogen load demands, present detailed planning for the wind-solar hydrogen production park under three typical scenarios. These findings reveal that factors such as hydrogen load demands and operational hours of wind and solar units influence the configuration of electricity-hydrogen storage and the capacity proportion of wind and solar entities. Furthermore, analyzing based on investment return periods offers valuable insights for operators in assessing investment risks.
