Battery Energy Storage Systems (BESSs) could\ud
contribute to the generation/consumption balance of the grid\ud
and could provide advanced functionalities at different grid\ud
levels (generation, T&D, end-user and RES integration). In this\ud
paper an analysis and comparison of Battery Energy Storage\ud
(BES) technologies for grid applications is carried out. The\ud
comparison is focused on the most installed technologies in the\ud
recent experimental BESS installations. Furthermore, the paper\ud
presents a new methodology aimed at selecting the most suitable\ud
BES technology for a specific grid application. This\ud
methodology defines a priority level for each technical and\ud
economical characteristic of the BES technologies. Finally, the\ud
proposed methodology is applied for a specific grid application\ud
confirming its contribution in the selection of the best-suited\ud
technology.Peer ReviewedPostprint (published version
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
