Abstract

The integration of high-penetration distributed new energy has made power quality problems in distribution networks increasingly serious. This paper mainly studies the evolution patterns of voltage deviation, harmonic coupling, and three-phase imbalance under clustered grid integration conditions, and establishes a safety regulation and control framework suited to complex scenarios. Through a combination of mechanism analysis and hierarchical cluster division, key technical paths such as multi-agent coordination, consensus control, and hybrid energy storage support are reviewed. The study shows that establishing a hierarchical architecture featuring global coordination, cluster autonomy, and terminal response, while giving full play to the flexible regulation role of inverters and energy storage, is an effective way to achieve coordinated and unified high-efficiency renewable energy accommodation and safe operation of distribution networks. In the future, the deep integration of artificial intelligence and situational awareness technologies should be promoted to strengthen the adaptive decision-making capability of control systems.
