Dynamic modeling and simulation of alkaline type electrolyzers

Abstract

Electrolyzers are essential part of power systems where the energy storage is in the form of hydrogen. Electrolyzers are used in remote hybrid power systems. In this research a dynamic model of an alkaline type electrolyzer has been developed. The MATLAB/ Simulink software has been used to form the generalized dynamic model, which can be integrated with different kinds of renewable energy systems. This paper describes the operation of electrolyzer cell by the electrochemical and thermal models and presents the simulation results graphically. This model is also suitable for steady state and transient analysis of a remote power system.
