This paper presents the design and simulation of a standalone photovoltaic (PV) system utilizing a DC-DC Buck-Boost converter, implemented in MATLAB/Simulink. The system comprises a solar PV array, the Buck-Boost converter, and both resistive (R) and resistive-inductive (RL) loads. Recognizing the intermittent nature of solar PV power output due to variations in cell temperature and solar irradiance, an Incremental Conductance (INC) Maximum Power Point Tracking (MPPT) algorithm is employed with the Buck-Boost converter to ensure maximum power extraction from the PV panels. Three distinct simulation cases are investigated: i) a closed-loop Buck-Boost converter with a DC supply, ii) the solar PV array integrated with the system, and iii) the complete system incorporating the INC MPPT algorithm. Simulation results consistently demonstrate that a stabilized and regulated output voltage is achieved for both R and RL loads, irrespective of fluctuations in the input voltage.
