This project is aimed at developing a model for an off-grid microgrid by studying the wind and solar resource at Östergarnsholm, an island to the east of Gotland, Sweden. For the required consumption, a study and analysis of Herrvik’s local demand has been made which is a village close to the island and the possibility for implementing the microgrid to supply electricity to the inhabitants of Herrvik has been examined. Renewable resource is paired with batteries for mitigating intermittency and using a generator running on biofuel is proposed during hours with no wind and sun.The data for wind and solar resource is obtained from Department of Earth Sciences, Uppsala University and household load is estimated for a typical detached Swedish house from a study funded by International Energy Agency. Microgrid is modelled and simulated in MATLAB and the simulation results show that the proposed microgrid can provide 100% availability for local load. Results also show that not only the inhabitants of the village can have their independent electricity supply for the whole year, but the excess electricity can also be used to desalinate the seawater at Herrvik’s desalination plant for around 90% of the time during the year.
