DC-DC converter based on maximum power point tracking techniques in standalone photovoltaic system

As is known, one of the obvious disadvantages of a photovoltaic system is the poor power output of solar radiation due to changing environmental conditions. Monitoring the maximum power point of the solar panel is a cost-effective and efficient approach to converting solar energy. The study explores methods of determining peak power point based on photovoltaic system disturbance. A comparative analysis will be made, highlighting the advantages and disadvantages of the approaches. The mathematical model and procedures of the system will be analyzed and the results will be reported. As an example, an analog control system is built for a hysteresis type DC voltage converter. The operation of a solar cell in partial shade is seen as a challenge for monitoring the maximum power point, and solutions to this problem are being explored. The study will focus on three typical strategies for monitoring MPPT: Perturb and Observe P&O; Incremental Conductivity IC; and Fuzzy Logic. A PI controller is attached and connected to the DC-DC converter to facilitate fast charging and extend the life of the battery. This system was analyzed and built using MATLAB/Simulink.
