Matching energy storage to small island electricity systems : a case study of the Azores
… under scenarios of increasing penetrations of variable-output wind. The analysis applies a least-cost unit commitment model to three Azores island networks (Sdo Miguel, Faial and Flores), in order to determine expected cost savings from introducing energy storage onto those systems. Modeling …
