The widespread use of renewable energy sources is hindered by their intermittent and unpredictable nature. This problem can be overcome with a storage system which manages the time mismatch between energy production and load requirements.The aim of this work is to develop a simulation tool for evaluating energy and economic performance of renewable energy islands, including various electricity generation technologies (photovoltaic modules, wind turbines and micro-hydroelectric plants), integrated with a hydrogen storage system, comprising an electrolyzer, a hydrogen storage tank and a fuel cell. After a brief description of the simulation tool structure, the attention is focused on energy and economic models of system components. Then an innovative approach for optimizing the energy island is proposed; it is based on a hybrid genetic-simulated annealing algorithm and aims to minimize the unit cost of electricity. Finally a generation island that provides electricity and hydrogen to a farm in central Italy is designed and optimized, comparing configurations based on different renewable technologies.
► We develop energy-economic models for renewable energy islands with hydrogen storage.
► An innovative approach is used for the objective function and minimization algorithm.
► The unit cost of energy can be evaluated for grid-connected and stand-alone systems.
► A hybrid genetic-simulated annealing algorithm is used for system optimization.
► A renewable island is optimized for providing electricity and hydrogen to a farm.
