============================================================
100 kW grid-connected solar photovoltaic (PV) system, focusing on the performance comparison between Perturb & Observe (P&O) MPPT and Fuzzy Logic MPPT techniques.

The PV array is designed using 330 W solar panels, configured with 5 series modules and 66 parallel strings, delivering a peak power of approximately 100.7 kW under standard test conditions. The system employs a DC–DC boost converter controlled by MPPT algorithms and a three-level inverter for efficient grid integration.
