Smart energy harvesting: coupled inductor-based HGISB converter integration with adaptive InCond MPPT for optimal grid performance

Amidst the burgeoning need for sustainable energy solutions worldwide, this article delves into a novel approach that amalgamates a photovoltaic (PV) system with a high-gain interleaved super boost converter, featuring innovative coupled inductors. The overarching goal is to amplify the voltage output of PV system, thereby optimizing power extraction and bolstering overall efficiency. Implementation of an adaptive incremental conductance maximum power point tracking algorithm ensures precise power tracking, while subsequent phases involve the conversion of DC to AC through a 1φ VSI combined with Proportional-Integral controller. This strategic integration aims to achieve seamless grid synchronization and mitigate harmonic distortions. Validation of proposed system is methodically undertaken using MATLAB simulations, revealing commendable performance metrics. With an impressive converter efficiency of 98.83% and a markedly reduced total harmonic distortion of 1.95%, this pioneering amalgamation not only meets the exigency for sustainable energy solutions but also emerges as a promising avenue for advancing dependability and efficacy of PV systems in the sphere of applications related to renewable energy sources.
