Abstract: A dual-layer optimization configuration model for hydrogen-containing comprehensive integrated parks under a steppedwise carbon trading scheme has been is proposed to better enhance optimize the low-carbon and economic operation within the comprehensive park. Firstly, heat storage and hydrogen storage systems are set up as individual energy storage investors, which are integrated with the stepwise carbon trading model to achieve and energy conversion is carried out by combining the stepped carbon trading model with the park. Secondly, the daily operation energy consumption of the comprehensive integrated energy park is taken as the upper objective function, and while the lower level is selected taken as the independent hydrogen and thermal energy storage planning cost as the objective function. In this way, to build a double-layer capacity optimization configuration model is established. The KKT constraints are used utilized to integrate the double-layer model and the large M method is employed for linearizedation, and then. Subsequently, the solver Gurobi is used to solve the problem. The calculation results show demonstrate that the energy storage as a separate sole investor to optimize the operation of the park can effectively reduce the carbon emissions released by during the system operation. In addition, it can economically reduce the construction costs of the park system while increasing energy storage revenues, thereby achieving the goals of both low-carbon and economic efficiency.
