A Lyapunov-based direct duty ratio MPPT strategy for PV–buck systems via resistance matching

MPPT control of a PV-battery system using a gain-scheduled adaptive PI controller and dual active bridge converter

Standalone photovoltaic-battery systems face significant challenges in maintaining optimal power extraction under rapidly varying irradiance conditions. Conventional MPPT controllers based on fixed-gain PI approaches suffer from poor dynamic response, oscillations around the maximum power point, and inability to adapt...

Load power matching MPPT for PV systems

Despite their common use, conventional MPPT algorithms, such as Perturb and Observe (P&O) and Incremental Conductance (INC), exhibit several limitations. These include oscillations around the MPP, delayed tracking response, and incorrect tracking direction when the system operates far from the true MPP. Such drawbacks...

Comparative analysis of advanced DC–DC converter topologies for enhanced solar PV system efficiency and stability

Data Science-Based Maximum Power Point Tracking Control for DC-DC Power Converters

Recent trends in renewable power conversion practices highlight maximum power point tracking (MPPT) for photovoltaic (PV)-fed Direct Current-Direct Current (DC-DC) converters, considering that variations in irradiance, temperature, and load fluctuation as well as partial shading generate diminution in energy extraction...

Constrained MPPT based control of a photovoltaic DC to DC conversion system using a non inverting buck boost converter

This paper presents a Constrained Maximum Power Point Tracking Algorithm (CMPPTA) integrated with a Non Inverting Buck Boost Converter (NIBBC) for photovoltaic (PV) energy conversion. Unlike conventional Perturb and Observe (P&O) methods, CMPPTA uses a constrained duty-cycle update law with adaptive bounded perturb...

HYBRID CONTROL FOR MAXIMUM POWER EXTRACTION AND VOLTAGE STABILITY IN PHOTOVOLTAIC-BATTERY SYSTEMS

Photovoltaic power systems face two main challenges: inefficient power extraction under variations in irradiance and temperature, and DC bus voltage instability due to power mismatches. This paper outlines the development, modeling, and simulation of a standalone PV system with battery storage and DC-DC converters, emp...
