摘要
为推进清洁能源多领域应用,从而实现“双碳”目标,提出了一种风光互补电醇联产系统。以新型电醇联产系统的年收益最大为目标函数,建立风光容量配比优化模型。选取内蒙古某地风-光-氢能生产基地的真实历史数据,对该系统进行仿真,并展开能量分析、经济性分析。新型风光互补电醇联产系统经过合理的风光容量优化配置和协同优化后,可以利用氢能的储能优势,保证甲醇合成设备在40%最低负荷率以上持续稳定生产。仿真结果表明,当光伏容量为25.4 MW、风电容量为74.6 MW时,新型电醇联产系统的弃电率降为2.9%,大幅提升了对新能源电力的消纳能力。此时,系统的全年净收益为1773万元,相比只有风电运行时的净收益提升了6.6%。该研究为风光氢醇多能互补提供了一条可行的技术路线,同时收获了良好的经济效益与环境效益。
In order to advance the application of clean energy in multiple fields and achieve the"dual carbon"target,a wind-solar complementary electricity-alcohol cogeneration system has been proposed.A capacity optimal allocation model for the wind-solar system is established subject to pursue the maximum annual revenue of the electricity-alcohol cogeneration system.Taking the historical data from a wind-solar-hydrogen production base in Inner Mongolia as an example,energy analysis and economic analysis are carried out on the proposed cogeneration system by simulation.The new cogeneration system proposed above can utilize the storage capacity of hydrogen energy after taking optimized configuration and collaborative schedule of wind and solar capacity,ensuring continuous and stable running of methanol synthesis equipment at its minimum load rate of 40%or above.The results show that when the photovoltaic capacity is 25.4 MW,and the wind power capacity is 74.6 MW,the system integrating electricity generation system with alcohol generation system can boost the renewable energy accommodation capacity with a 2.9%decrease in renewable energy curtailment rate.Meanwhile,the annual net income of the new system is 17.73 million yuan,6.6%higher than that of the system without alcohol generation system.The research provides a feasible technical roadmap for the multi-energy complementation system,with decent economic and environmental benefits.
