Optimization Scheduling of Integrated Park Energy Systems with Hydrogen Energy Storage Based on Hybrid Copula.

This article focuses on improving energy utilization efficiency and renewable energy integration in comprehensive energy parks by developing an optimized power system scheduling model that incorporates hydrogen energy storage and a hybrid copula-based joint output model for wind power and photovoltaics. The hybrid copula theory is used to accurately capture the complex correlation between wind and solar power outputs, reducing their uncertainty in grid connection. Hydrogen energy storage equipment participates in the power system scheduling to buffer renewable energy fluctuations, enabling bidirectional conversion between electricity and hydrogen, which enhances system flexibility and renewable energy consumption. Case studies demonstrate that the proposed model reduces operating costs by 14.15%, decreases thermal power output by 32.54%, and increases combined wind-solar output by 30.9%, highlighting its effectiveness in economic optimization and sustainable energy management within integrated energy parks.
