Can pumped hydro storage facilitate renewable penetration in Islands?

In , the hybridization of wind generation with the introduction of pumped hydro storage systems is investigated. The findings indicate that these integrated storage and RES facilities have the potential to facilitate increased renewable penetration levels in islands without compromising system stability.

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 is pumped hydro storage & battery energy storage (BES)?

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. Pumped hydro was the default technology of choice up to some years ago due to its technical maturity and the hydro resources available in certain islands [41, 77].

Are pumped-hydro stations a viable storage option for HPS applications?

Up to 2019, the leading storage technology investigated in the literature for HPS applications was the pumped-hydro stations [32, , , , , ], which were perceived to be the most suitable and probably the sole economically feasible storage alternative.

What is the HPS design for island systems?

The HPS design for island systems was initially introduced by the work of , , where the El Hierro island was used as the case study to achieve a promising >70 % penetration of renewables, combining wind farms and pumped hydro-storage facilities.

Which storage typologies are suitable for deployment in island systems?

The review process identified three main storage typologies suitable for deployment in island systems: (a) storage coupled with RES within a hybrid power station, (b) centrally managed standalone storage installations, and (c) behind-the-meter storage installations. Of particular interest are the former two, which dominate the relevant literature.
