MATLAB Simscape Model of An Alkaline Electrolyser and Its Simulation with A Directly Coupled PV Module for Auckland Solar Irradiance Profile

A MATLAB/Simulink/Simscape power systems implementation of an alkaline electrolyser directly coupled by a photovoltaic module is presented and evaluated. A simulation is run using average daily irradiance and temperature data for a typical summer and winter day in Auckland New Zealand and the trend results are compared with several published studies. Results show full range of electrolyser characteristics. The characteristic profile matches the results from the published papers. Numerical results for input energy, amount of hydrogen produced, and efficiency are also presented.
