Off-Grid Power Management for a Home Integrating Electric Vehicle and Photovoltaic System Under Energy Constraints
Main Article Content
Abstract
Energy management is an increasingly studied field, attracting the attention of researchers and industry professionals, particularly in off-grid applications. This study focuses on the sizing, modeling, and control of an off-grid residential home powered by photovoltaic panels and integrated with an electric vehicle. The house uses photovoltaic panels as the main energy source, a battery for energy storage, and an electric vehicle as the main load in the system. Power converters interconnect system components, enabling voltage and current control for efficient energy flow management. The proposed strategy aims to balance energy at the household level, manage the battery state of charge, and ensure the fully charging of the electric vehicle before departure. Key contributions include a control framework that ensures continuous power supply for residential needs while optimizing electric vehicle integration. The approach addresses challenges in electric vehicle charging within isolated energy systems and supports dynamic energy distribution. Results demonstrate that the off-grid system meets energy demands effectively, validating both the sizing methodology and control strategy. The management solution improves energy reliability, enhances user comfort, and contributes to sustainable living by maximizing renewable energy use and ensuring energy autonomy for off-grid households.
