Sažetak
A stand-alone energy system consisting of a PV array, wind turbine, electrolyzer, hydrogen storage, fuel cells and a battery bank is analyzed. The energy management strategy used for this system is based on double hysteresis control loops where battery state of charge is used to trigger the electrolyzer and the fuel cells switching on/off. A simulation code using Matlab is developed. The end-user load is defined as constant, while the input weather data is acquired from Croatian Meteorological and Hydrological service. Simulations are conducted using two different electrolyzer operation points: (i) maximum power point and (ii) maximum efficiency point. Values of the electrolyzer power, battery bank size and battery state of charge for the electrolyzer control vary for each simulation. Simulation results indicate that the change of any parameter affects both the system efficiency and the electrolyzer average operation time.
