Data for: A scheduling framework for seawater pumped hydro energy storage in a hybrid photovoltaic-wind island system

This dataset supports the manuscript "A scheduling framework for seawater pumped hydro energy storage in a hybrid photovoltaic-wind island system". It contains the processed renewable-resource, demand, price and derived result files used to reproduce the tables and figures in the paper. The dataset includes hourly PV and wind capacity-factor series, demand and price inputs, deterministic multi-scale summaries, stochastic scenario outputs, tidal lower-bound maps, MILP-Orchard benchmark results, ancillary-service runs, technology-comparison outputs, and CO2/price-shape sensitivity data. Optimisation source code is not included in this data release and will be released separately after cleaning and documentation.
