A Comparative Analysis of Different Standalone PV System Topologies Using Fuzzy Logic-Based MPPT Technique

With the growing worldwide need for renewable energy sources, standalone photovoltaic (PV) systems have gained great importance. Maximizing the efficiency of these systems is critical for optimal energy extraction. This paper conducts a comparative analysis of different topologies of photovoltaic (PV) panels with boost converters in the context of standalone PV systems, focusing on the optimization of power production by integrating a fuzzy logic technique for Maximum Power Point Tracking (MPPT). Through the simulation, Different PV panel topologies are tested alongside different boost converter topologies to assess their performance under non-uniform irradiation. In addition, the efficiency, tracking accuracy, and system stability, are evaluated to quantify the effectiveness of each topology. This study provides valuable information for selecting the most suitable topology of PV array and boost converter for grid-connected PV systems. The results obtained prove that parallel topology outperforms series topology in terms of efficiency and energy generated. Furthermore, this research validates the significance of employing sophisticated algorithms, such as fuzzy logic, to improve the operational effectiveness of standalone photovoltaic systems.
