System performance analysis of an isolated microgrid with renewable energy sources and a battery and hydrogen storage system - An evaluation of different storage system configurations

Abstract: As more renewable and intermittent power sources are incorporated into the grid, the need for energy storage solutions increases. Implementation of hybrid energy storage solutions (HESS) could enhance system flexibility and contribute to the development of renewable energy systems. The purpose of this master thesis project is to investigate the technical and economic viability of different configurations of battery and hydrogen storage solutions in an isolated microgrid, i.e. local energy system (LES), with renewable power generation. The thesis strives to answer what operation and control strategies are necessary, what sizing methods are suitable and what measurements of performance that could be used to evaluate the system. Simulations are made over a one-year period with a resolution of one hour and use actual data for production and consumption of a microgrid implemented in Simris run by E.ON.
