As pivotal infrastructure for energy transition

hybrid AC/DC distribution systems are undergoing profound transformations-evolving from centralized to distributed topologies and shifting from unidirectional power delivery to multi-node collaborative operation. The extensive integration of renewable energy sources and diversified loads imposes heightened demands on system flexibility

reliability

and security. Distributed control technology

leveraging multi-layer coordination and intelligent decision-making

has emerged as a critical pathway to address these challenges. First

this paper analyzes the multi-level coupling interactions in AC/DC distribution systems and clarifies a cross-layer collaborative architecture across multiple time scales. Second

it reviews three major dimensions: system-level and device-level distributed control

event-triggered mechanisms

and cybersecurity attack-defense. By establishing technical closed loops such as dispatch-control coordination and distributed control architectures

a "global optimization-hierarchical execution" regulation framework is constructed. Additionally

this paper introduces event-triggered mechanisms and cybersecurity measures to form a dual guarantee of "efficiency-security". Finally

the paper explores future trends in distributed control for AC/DC distribution systems and analyzes key technical bottlenecks and future development pathways.
