Harmonic Minimization and Voltage Boosting In PV-based Multilevel Inverter Using Advanced Deep Learning Approach
Abstract
The integration of photovoltaic (PV) systems with multilevel inverters has gained significant attention due to their capability of producing smooth output waveforms with fewer distortions. However, conventional modulation and optimization techniques often face limitations in minimizing total harmonic distortion (THD) while simultaneously improving voltage levels under varying solar irradiance conditions. To address these issues, this work proposes an advanced deep learning-based framework for harmonic minimization and voltage boosting in PV-driven multilevel inverters. The suggested framework analyses inverter operating characteristics and finds the best switching patterns for enhanced power conversion using intelligent learning techniques. It seeks to maintain steady inverter performance in the face of changing environmental circumstances, improve output voltage quality, and lower harmonic components. To facilitate adaptive management and effective energy use, the framework also takes fluctuations in solar irradiance and photovoltaic output voltage into account. Additionally, the use of deep learning facilitates data-driven decision-making, which may lessen reliance on traditional optimization techniques and enhance inverter control responsiveness. Key metrics such as total harmonic distortion, output voltage magnitude, conversion efficiency, and dynamic responsiveness under various operating situations may be used to assess the effectiveness of the suggested method. This research aims to provide a practical method for enhancing power quality and voltage management in solar photovoltaic applications by fusing deep learning with multilayer inverter control. Potential advantages for distributed generation, solar power conversion systems' dependable operation, and the integration of renewable energy are provided by the suggested framework.
