Analysis of the performance of a Power-to-Power system based on hydrogen and batteries installed in Norway within the REMOTE project

The idea for the drafting of this graduation thesis starts from the realization of the European funded project REMOTE, within the broader Horizon 2020 program. The project involves the installation of three demonstration sites in three different European areas and we took care of the Norwegian one, which was built in Rye. The purpose of this demonstration site was to evaluate the feasibility of operating as a microgrid in islanding mode, i.e. disconnected from the public grid, using renewable energy sources coupled with innovative hybrid storage systems including hydrogen and batteries. The purpose of this paper is to analyze the data collected for each single component of the plant, re-elaborate them in a graphic and intuitive format and extract performance indicators (KPIs) to draw effective conclusions on the functioning of the demo. After an introductory section on components and management of the system, the in-depth analyzes are of three types: I.??Power analysis: information regarding powers, states of charge, efficiencies and significant quantities is extrapolated. II.??Energy analysis: information on incoming, outgoing, self-consumption energy flows and total balances is obtained. III.??Fault analysis: downtime, component blackouts and periods of connection to the public network are analyzed to estimate the reliability of the systems. The final chapter focuses more on the environmental impacts of this project. An emissions analysis of DEMO Norway is carried out and comparisons between different plant solutions, different energy generations and different site locations are made. The Key Performance Indicators we obtain concern the load, renewable energy sources and storage as a whole, thus providing us with a significant view of the operation of this type of microgrid. The results obtained are truly comforting with low need for connection to the public grid, high efficiencies of the power-to-power system and low emissions produced.
