Optimizing stand-alone PV systems: A metaheuristic-enhanced fuzzy approach for adaptive MPPT

This paper introduces a simple yet effective approach for developing fuzzy logic controllers (FLCs) to identify the maximum power point (MPP) and optimize the photovoltaic (PV) system to extract the maximum power in different environmental conditions. We propose a robust FLC with low computational complexity by reducing the number of membership functions and rules. To optimize the performance of the FLC, metaheuristic algorithms are employed to determine the parameters of the FLC. We evaluate the proposed FLC in various panel configurations under different environmental conditions. The results indicate that the proposed FLC can easily adapt to various panel configurations and perform better than other benchmarks in terms of enhanced stability, responsiveness, and power transfer under various scenarios.
