Considering the comprehensive energy system scheduling of hydrogen energy

To tackle the scheduling challenges in industrial park integrated energy systems, this study incorporates diverse energy storage forms within an electric-thermal-hydrogen coupling framework and optimizes them across multiple time scales, from day-ahead to intraday. Initially, system and equipment modeling are performed for the integrated energy system of industrial parks, incorporating the coupling of electricity, heat, and hydrogen. Subsequently, a day-ahead to intraday multi-time scale optimization model is developed. Lastly, by incorporating additional energy storage forms, four distinct hydrogen production scenarios are created for simulation and validation. Experimental results demonstrate that equipping with multiple energy storage forms enhances both the economic efficiency and environmental sustainability of the system.
