A NOVEL TRANSFORMERLESS PROTECTION SCHEME FOR VOLTAGE REGULATION IN DISTRIBUTION GRIDS

Abstract

This work introduces a groundbreaking transformerless protection approach to improve voltage regulation in current distribution circuits. In order to maintain voltage stability regardless of changes in loads or defects, the proposed method uses sophisticated power electronic converters and astute control procedures, doing away with the necessity for conventional transformers. Adaptive compensatory mechanisms, real-time monitoring, and quick problem detection enable the system to reduce system size, cost, and energy losses, resulting in dependable operation. The proposed method successfully mitigates voltage fluctuations, increases power quality, and provides robust protection against overvoltage and undervoltage scenarios, according to both experimental and theoretical findings. The transformerless design is a great fit for next-gen smart distribution networks since it can increase system efficiency and facilitate the integration of renewable energy sources.
