Abstract: 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.
