This study addresses the feasibility, sizing, and scheduling of an island micro‐grid involving photovoltaic, wind turbine, diesel generator, and battery energy storage systems. In addition, the end‐use demand is expanded beyond residential electricity loads, as the full electrification on domestic water supply and transportation, in the forms of desalination and electric vehicles (EVs), are proposed in this study with integration to a renewable energy system focused micro‐grid. A mixed integer linear programming model is constructed to explore the mutual interactions of desalination plant, vehicle‐to‐grid enabled EVs and residential load deferring on a micro‐grid. A case study in Bruny Island, Australia was incorporated in the study, based on the existing infrastructure and future planning. Multiple scenarios were run utilizing real‐world, fine resolution time‐series data. Results were compared to investigate the impact of the polygeneration configuration and potential economic savings on household affordability. Our study displayed the advantage of electrifying and integrating household resources into the micro‐grid, such as transportation and water filtration. The integration created a greater diversity in electricity end‐uses, allowed for better scheduling and Renewable System management. In addition, the cost‐benefit analysis of stationary battery storage units was modeled against the other forms of energy storage, such as electric vehicles and seawater desalination plant, with findings suggesting the potential economic advantage of storage other than grid connected batteries in a residential precinct.
