Abstract

Integrating photovoltaic (PV) systems into the grid has seen a surge, predominantly due to the quest for clean, reliable, and sustainable energy. However, high PV penetration results in reliability issues due to the PV system's power electronic converters (PECs). This drawback has resulted in grid uncertainties and further limits the high growth of PV systems. In order to mitigate these challenges, this paper presents a comprehensive reliability analysis of PECs essential for the seamless integration of PV systems. The converter topology of the PV system is modeled and simulated under various operating conditions by employing MATLAB/Simulink and PLECS tools. The study also explored dynamic behavior, potential failure modes, and the lifetime of PV components, focusing on the impacts of temperature variations, component aging, and electrical stress. The results will inform future design and operational strategies, contributing to energy reliability and grid modernization, ultimately supporting the broader goal of enhancing the large-scale integration of PV technologies into Georgia's grid.
