Dataset: PV-PEM Electrolyzer System Simulation for Transient Solar Irradiance Analysis

This dataset contains the MATLAB/Simulink simulation model, function files, results, and publication figures for a 12 kWp photovoltaic array coupled to a 50-cell PEM electrolyzer stack through an MPPT-controlled DC-DC buck converter under stepwise solar irradiance variations (400–1000 W/m²). Contents:- Simulink_Model/: Main Simulink model file (.slx)- MATLAB_Functions/: Function files for PV array, MPPT controller, and PEM electrolyzer- Simulation_Results/: Simulation output data (.mat)- Scripts/: Post-processing and plotting scripts (.m)- Figures/: Publication-quality figures (.png and .fig) Software requirements: MATLAB R2026a or later, Simulink.
