Modeling and Simulation Control of MPPT in Solar Array for Green Hydrogen Production

This article addresses the critical challenge of optimizing solar array performance for electrolysis-based green hydrogen generation. A fuzzy logic controller (FLC) for maximum power point tracking (MPPT) was proposed in this study to maximize the performance of solar arrays in electrolysis-based hydrogen generation. The FLC does away with the need for traditional methods like Perturb and Observe (P&O) by dynamically adjusting the DC-DC converter duty cycle based on real-time temperature and irradiance inputs. Under various climatic conditions, MATLAB/Simulink simulations show a 92% operational efficiency and a 25% increase in hydrogen output, surpassing P&O (78%) and Incremental Conductance (82%). The FLC is a reliable option for scaling renewable energy systems because of its versatility and inexpensive computational cost.
