Optimal configuration of seasonal and short-term storage system for an island electricity-hydrogen integrated energy system

Hydrogen energy and energy storage have been identified as one of the Chinese six future industries. The utilization of hydrogen energy will accelerate the carbon neutral goal. Under the background of integrated energy system (IES), the energy storage system will be more widely used. This paper studies configuration of optimal configuration of seasonal and short-term storage system for an island electricity-hydrogen IES. Firstly, an islanded IES model with seasonal and short-term storage system is established. Then, aiming at economy, the optimal configuration model of seasonal and short-term storage system is established. Finally, the proposition for improvement and study of next stage is given.
