In order to improve the energy utilization efficiency of the comprehensive energy park and the proportion of renewable energy grid connection, this paper first proposes to use the hybrid copula theory to construct a wind power and photovoltaics joint output model, reducing the uncertainty of wind power output and photovoltaic output. Secondly, this paper proposes the participation of hydrogen energy storage equipment in the power system scheduling of integrated energy parks. Hydrogen energy storage, as a clean, efficient, and sustainable carbon-free energy storage technology, can be used to mitigate the impact of wind power and photovoltaics output on the power grid. Finally, this paper proposes to construct an optimized scheduling model that considers economic optimization and proves the economic feasibility of the model through case analysis. The calculation results show that the comprehensive energy operating cost has been reduced by 14.15%, the proportion of thermal power output has been reduced by 32.54%, and the proportion of wind solar combined output has increased by 30.9%.
