    Wind and solar curtailment is a major problem in the rapid development of new energy, which can be effectively solved by adopting a comprehensive energy architecture and developing multiple conversion technologies. This paper focuses on the integrated energy system (IES) with water electrolysis to hydrogen production technology as the core. Based on the analysis of the operating characteristics and mathematical modeling of the water electrolysis device, a two-layer optimization model of the hydrogencoupled IES was proposed. The optimal capacity of hydrogen energy storage is obtained by using the datadriven double-layer mixed integer nonlinear optimization (DOMINO) algorithm as the solution method,taking the optimal operation problem of IES with hydrogen coupling as the lower-level optimization problem, and the capacity optimization of hydrogen energy storage as the upper-level optimization problem. Finally, through simulation analysis, the convergence of the algorithm and the optimal hydrogen capacity are analyzed.

    Keywords: IES, Hydrogen production efficiency, Double-layer optimization problem, domino algorithm, Capacity configuration
