Light-fire-hydrogen polycrystalline silicon park optimal configuration method based on multivariate Copula function

According to the light-fire-hydrogen polycrystalline silicon park optimal configuration method based on the multi-element Copula function, photovoltaic hydrogen production is introduced according to the energy supply characteristics and the low-carbon requirement of a polycrystalline silicon park, and a traditional polycrystalline silicon park energy system is optimized. A multi-element Copula function is used for representing light-electricity-hydrogen source-load correlation, and a light-fire-hydrogen polycrystalline silicon park double-layer optimization configuration model is constructed in combination with all coupling links and production processes of the system. The upper layer is a planning model with the optimal operation cost of the park equipment as a target, the lower layer is a low-carbon scheduling model with the lowest comprehensive operation cost of the system as a target, and the optimal capacity of the equipment is determined through iteration. By taking a certain polycrystalline silicon par
