Study on the Optimizing Impact of Hydrogen Equipment in Integrated Energy Systems

In recent years, comprehensive energy systems have emerged as a focal point of research. However, the practical application of hydrogen energy as a primary source within these systems necessitates further investigation. This paper systematically reviews common physical models of electrical, thermal, cooling, storage, and hydrogen energy devices. By establishing a mixed-integer linear programming model, with a primary objective of overall economic optimization, considering energy balance constraints and equipment operational constraints, the paper computes the optimal configuration of comprehensive energy systems considering the utilization of hydrogen energy devices. Furthermore, the study analyzes the impact of fluctuations in hydrogen energy prices on the configuration results. It is observed that the interconnection of different types of comprehensive energy devices can enhance energy efficiency, and the integration of hydrogen energy devices can lead to a reduction in the total cost of the system through hydrogen sales.
