Modelling the water-energy nexus of the future smart island

Following the signing of the Paris Climate Agreement and the adoption of the European Green Deal, which aims to make Europe the first climate-neutral continent, research into the sustainable development of energy, water and environmental systems is increasingly focusing on studying the complex relationship between water and energy systems. Water system is being modelled using the EPANET model. EPANET is an open source software used for hydraulic modelling of water supply systems and analysis that includes optimizing the operation of pumps and water tanks, reducing electricity consumption etc. Optimal connection between water and energy system is studied using the Calliope tool. Calliope is free and open-source multi-scale energy systems modelling framework used for optimization analysis of the water-energy nexus. The approach was used for the analysis of a future water system on the Unije Island as part of the INSULAE project. Project also includes implementation of PV and battery system, which are modelled as part of an existing energy system. Different scenarios of water system management were studied. Using aforementioned approach optimal water tank volume was calculated, while preventing occurrence of unmet water demand. Moreover, scenario of using individual household water reservoirs was studied, while also preventing the occurrence of unmet water demand in each hour of a one-year time period.
