Wind powered pumped-hydro storage systems for remote islands: A complete sensitivity analysis based on economic perspectives

► Electricity production in most remote islands is based on expensive oil imports. ► The contribution of wind power is restricted due to electrical grid limitations. ► The techno-economic behavior of a wind-based pumped hydro storage system is examined. ► Guaranteed energy amounts at peak load demand hours are provided by the proposed system. ► Based on the optimum solution renewables may cover 25% of the island's energy needs.
