This paper reviews both conventional and artificial intelligence (AI)-based control methods for GCPI. It compares their performance characteristics, application scenarios, and limitations and summarizes current research progress and remaining challenges. This is where power electronics devices like converters are crucial in ensuring the proper. . Single-phase grid-connected inverters have become the cornerstone of distributed renewable energy systems, particularly in residential photovoltaic installations and small-scale wind energy systems. Unlike grid-following inverters, which rely on phase-locked loops (PLLs) for synchronization and require a stable grid connection, GFMIs internally. .
