The present work is performed in the framework of the EU REMOTE project, whose aim is to assess the feasibility of microgrids that rely on renewable sources coupled with hybrid energy storages based on hydrogen and batteries. REMOTE installed three Demo plants in different sites, featuring different RES and storage sizes. The aim of this Master’s Thesis is to quantitatively analyse real data collected from REMOTE’s Demo Norway, located in Rye, in order to compute the energy produced by the different sources, load’s consumption and storage use, with the final objective to calculate some Key Performance Indicators. These KPIs are used to actually evaluate how the load is supplied using the different sources or discharging the storages, how the RES production is used in terms of storage and load supply, and the actual operation of the storages in terms of round trip efficiency.
