Abstract

In recent years, Renewable Energy Sources (RES) have gained substantial importance in the global energy generation landscape, offering numerous environmental and economic benefits. This paper presents a highly efficient Photovoltaic (PV) grid-tied system utilizing a novel High-Gain Modified Re-Boost Luo (HG-MRBL) converter, designed to optimize energy generation. For attaining optimal energy production from solar panels, Maximum Power Point Tracking (MPPT) is employed using Jellyfish Search Algorithm, by an Adaptive Neuro-Fuzzy Inference System (JSA-ANFIS). An HG-MRBL converter processes the PV system's output to raise Direct Current (DC) voltage to the necessary levels for grid interaction. A three-phase Voltage Source Inverter (VSI) applied for converting this DC supply into AC. To minimize harmonics and guarantee seamless grid integration, the VSI is connected to an LC filter. Proportional Integral (PI) controller utilized for controlling injection of both active and reactive power into grid to manage flow of power. The system's efficiency is validated using MATLAB simulation, revealing the highest converter efficiency of 94.31%, which surpasses the performance of state-of-the-art approaches.
