Capacity configuration-operation scheduling optimization and economic analysis of the off grid wind and solar hydrogen alcohol integrated system
To solve the difficult problems of renewable energy consumption,hydrogen energy storage and transportation,an off grid integrated system for wind,solar,hydrogen and ethanol is proposed.The system operates offline,utilizing wind and photovoltaic power generation to provide electrical energy.By using batteries and hydrogen storage tanks as energy storage and hydrogen storage equipment,electricity and hydrogen energy is stably supplied in a peak shaving and valley filling manner,ensuring the stable and continuous production of methanol in the electrolytic cell and methanol generation equipment.A mathematical model for solar energy hydrogen storage alcohol is constructed with the goal of maximizing the total system revenue,and the optimal equipment capacity and operation scheduling of the system is determined through mixed integer linear programming algorithm combined with real solar energy data analysis.The operating strategy and the system energy of the system on a typical day is analyzed,and finally the economic performance of the produced green methanol is investigated.The results indicate that,the system can switch operating states reasonably based on changes in external conditions,thus to achieve energy balance in the system.On the premise of meeting various constraints,the utilization rate of renewable energy is improved and the leveling cost of methanol production in the system is reduced.This study proposes a feasible technical route for the consumption of new energy and the utilization of hydrogen energy,and provides certain guidance for the construction of related demonstration projects.
