What are storage services & architectures in Islands?

Storage services and architectures in islands are identified. Two storage designs emerge as of particular interest. Storage operating principles, remuneration schemes, and investments feasibility are discussed. Electricity storage is crucial for power systems to achieve higher levels of renewable energy penetration.

Do Island power systems have centrally managed storage facilities?

Centrally managed storage facilities in island power systems dominate the relevant literature. Table 4 includes the papers dealing with the centrally managed storage concept. Table S2 of the Supplementary data and Fig. 7 present additional details for the most representative ones.

What are the best storage technologies for Islands?

Ιn , batteries and pumped-hydro storage have been identified as the leading storage technologies for islands, with the former effectively applicable to small and medium size system and the latter to large systems with natural reservoirs.

How important are energy storage stations in Nii?

Undoubtedly, energy storage stations (ESS) are vital for the electricity sector of NII to move to penetrations of renewables over 50 %. As can be inferred from Table 1, pumped hydro storage (PHS) and battery energy storage (BES) technologies dominate the landscape of actual grid-scale applications for island systems.

What are the different storage typologies for Island applications?

The review eventually emphasizes the two predominant storage typologies for island applications; the centralized storage concept, where storage operates independently of renewable installations, and a hybrid concept, in which storage and renewables cooperate to inject controllable RES energy into the island grid.

Is storage an instrument to achieve high-res penetration levels in Islands?

The value of storage as an instrument to achieve high-RES penetration levels in islands is also discussed, reviewing several available articles investigating RES penetrations from approximately 10 % to 100 %. Additionally, the services provided by storage in NIIs systems, and the respective storage designs available are recognized.
