COMPARISON OF MPPT ALGORITHMS FOR DC-DC BOOST CONVERTER IN GRID-TIED PHOTOVOLTAIC SYSTEMS

In unpredictable weather circumstances, maximum power point tracking (MPPT) approach critical for ensuring maximum photovoltaic (PV) output power is extracted. In this paper, we will compare the incremental conductance algorithm (IC), perturb and observe (p & o), and fuzzy logic controller (FLC) as maximum power point tracking (MPPT) techniques. The three algorithms were used on a photovoltaic energy conversion system that was linked to grid. The suggested methodologies investigate the photovoltaic (PV) system's solar energy conversion performance under various irradiance and temperature circumstances. Lastly, a performance comparison between IC, P O, and FLC has been performed, demonstrating the superiority of the fuzzy controller over the other proaches. FLC converts photovoltaic electricity readily, reducing fluctuations, and it responds quickly to variations in solar irradiation (the shading effect). The simulation results demonstrate that the controller ing fuzzy logic performs well, allowing the inverter convert the electricity provided by the solar panels.
