Since the ocean may be regarded as an infinite natural reservoir, building seawater-pumped storage stations on islands has some natural advantages. These pumped-storage stations play an auxiliary role in island power supply and can be considered as a new type of energy storage system [ 11, 12 ].
The emergence of seawater-pumped storage stations provides a new method to offset the shortage of island power supply. In this study, an optimal scheduling of island microgrid is proposed, which uses seawater-pumped storage station as the energy storage equipment to cooperate with wind, photovoltaic and diesel generator.
However, by introducing seawater-pumped storage station, the curtailments of rigid loads and renewable energy were reduced, and the expense growth of island microgrid would become slower. Hence, the scheduling model proposed in this study could reduce the total operation and maintenance costs of island microgrid system obviously. 5. Conclusions
In addition, some Japanese scholars have carried out theoretical research in the field of power system with seawater-pumped storage stations and renewable energy. For example, a construction and operation scheme of seawater-pumped storage station is proposed in reference [ 14 ].
In this deep dive, we''ll explore how cutting-edge energy storage is rewriting the rules of island power management, complete with real-world success stories you can''t afford to miss. An
