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. System’s operation will also be analysed in terms of working time, required maintenance, faults and blackouts of each component; the required grid connection time will be calculated. Then a computational model of the system will be constructed in Simulink environment, featuring all components present in Demo Norway. This model will be used to analyse the dynamic operation of the microgrid. Model validation will be done by exploiting real weather and load data collected at Demo Norway. All components are treated according to a lumped dynamic model approach. In the end, some case studies will be presented to qualitatively assess the real intervention of the different sources basing on energy production from RES, load consumption and storage availability. In conclusion, it will be possible to have a general overview of a microgrid relying on RES that is able to operate in islanding mode by exploiting the availability of a power-to-power hybrid storage system based on batteries and hydrogen. Besides the feasibility of the system, the most important goal achieved is the quite high efficiency of the global power-to-power storage system: the global P2P storage, involving both battery and hydrogen, allows to reach an efficiency even higher than 60%, with a G2P efficiency calculated for the fuel cell operation always higher than 45%. Furthermore, during the period under analysis, the system required grid connection for less than 25% of time, even if most of the necessary connection have been caused by components’ commissioning and installation.
