TL;DRAbstract

The topic of this thesis is investigation of a small-scale stand-alone power system, based on both experimental work and computer simulations. The power system in this study uses solar energy as energy input, lead-acid batteries as short-term energy storage, and hydrogen as long-term energy storage. The main focus is upon operation and control of the hydrogen subsystem, as a robust controller is needed in order to prevent excessive use of the components in this subsystem. The laboratory power system comprises of: Hydrogen subsystem (PEM electrolyser, metal hydride, and PEM fuel cell), a lead-acid battery, programmable power supply for emulation of PV arrays, wind turbines, and controlled characterisation of the individual system components, and a programmable electronic load. \n\nThe intention was to build the laboratory power system as simple and energy efficient as possible. The components were connected directly in parallel on a common 48 V DC bus bar, no power electronics were appl
