Integrated Energy Systems (IESs) focus on coordinating energy consumption management, storage, and resources, often including renewable sources like tidal units, photovoltaic systems, wind systems, and bio-waste systems. The unpredictable nature of renewable energy generation requires the utilization of storage devices in IES to optimize energy management and compensate for power fluctuations. Among these storage devices, hydrogen storage stands out for its hydrogen-to-power (H2P) and power-to-hydrogen (P2H) technologies, making it a valuable asset for storing electrical energy and supplying hydrogen. IESs with optimal operation contribute to improved technical and economic objectives for distribution system operators by enhancing energy transfer and storage capabilities. Various optimization models and methods have been proposed in the literature to address IES planning and operation, with a particular emphasis on integrating hydrogen storage technologies. Studies have shown that hydrogen storage plays a significant role in reducing environmental costs, optimizing renewable energy capacity, and improving the overall efficiency of integrated energy systems. These findings underscore the positive impact of hydrogen storage in IES and its potential for enhancing sustainability in energy management.
