Abstract

This paper presents a comprehensive methodology for the selection of power semiconductor devices in a standalone photovoltaic (PV)-battery system (SPBS) based on power loss analysis. The SPBS configuration is modeled analytically, and the waveforms for the system are obtained in a Hardware-In-the-Loop (HIL) and by simulation environment using Matlab. The study focuses on identifying the most cost-effective power semiconductor devices by assessing power loss at three distinct operating points. The algorithm evaluates losses in each component, facilitating the selection of optimal devices for enhanced system performance. The evaluation is performed for different operational modes, incorporating worst-case scenarios for current and voltage, providing a robust analysis of system behavior. By emphasizing the importance of power loss analysis in isolated PV systems, this research contributes to the advancement of energy efficiency in SPBS. The proposed methodology enables the identification of power semiconductor devices experiencing the highest losses, aiding in the selection of components that minimize overall losses and maximize energy utilization from PV panels and batteries.
