The integration of photovoltaic (PV) systems into the grid necessitates efficient power conversion and control strategies to ensure stable and reliable operation. This study compares two single-phase PV grid-connected configurations: a single-stage inverter topology and a boost-assisted single-stage inverter topology. To maximize power extraction, the Incremental Conductance (IncCond) algorithm is employed for Maximum Power Point Tracking (MPPT). The control approach relies on real-time voltage and current feedback, utilizing p-q theory for effective power regulation. MATLAB/Simulink simulations evaluate system dynamics, power quality, and overall efficiency. The findings highlight the advantages and trade-offs of integrating a boost converter in a single-stage PV grid-connected system, offering valuable insights for optimizing performance.
