为实现"双碳"目标,推进氢能多领域应用,设计一种风光互补制氢合成绿色甲醇系统,提出面向电化工(P2X)系统的Copula-Shuffle风光出力不确定性与相关性调度场景生成方法.基于所提系统内各设备运行特性,以净收益最大为适应度函数建立两阶段随机优化模型并进行仿真分析.结果表明,所提系统经过设计调度优化后,利用电解槽启停待调度及氢储能灵活调控,主动平抑风光不稳定输出,满足绿色甲醇合成设备的柔性变负荷调节与连续生产约束,实现各设备间的深度协同运行.所提系统可充分消纳新能源电力,具有初步盈利能力,研究成果可为绿色甲醇产业提供一定的指导.
TWO STAGE STOCHASTIC OPTIMIZATION OF GREEN METHANOL SYNTHESIS SYSTEM BASED ON COPULA SHUFFLE METHOD FOR SOLAR HYDROGEN PRODUCTION
To achieve the dual carbon goal and promote the multi-domain application of hydrogen energy,this paper designs a scenery complementary hydrogen production and synthesis green methanol system,and proposes a Copula-Shuffle scenery output uncertainty and correlation scheduling scenario generation method for electrochemical(power-to-X,P2X)systems.Based on the operating characteristics of each equipment in the new system,a two-stage stochastic optimization model is established and simulated with the maximum net benefit as the fitness function.The results show that after the design and scheduling optimization,the new system makes use of the electrolyzer start-stop standby scheduling and the flexible regulation of hydrogen storage to actively suppress the unstable output of scenery and meet the flexible variable load regulation and continuous production constraints of the green methanol synthesis equipment,and realize the deep synergistic operation of each equipment.The new system can fully consume new energy power and has initial profitability.The research results can provide some guidance for the green methanol industry.
