摘要
分布式智能电网是“双碳”目标下新型电力系统建设的重要组成部分,是支撑新型电力系统朝清洁低碳、安全充裕、经济高效、供需协同、灵活智能方向迈进的重要抓手。该文综合国内外发展现状,分析了新型电力系统中源网荷储的发展趋势与新特征,以及新发展趋势带来的技术瓶颈。阐述了分布式智能电网的内涵与技术特征,其核心在于对现有电网网络架构与运行控制方式的智能重构,并提出了分布式智能电网的组织方式、结构形态与控制框架。进而,分别从分布式单元建模与协同、分布式集群划分与交互、分布式电网优化与控制3个层面构建了分布式智能电网的理论框架,阐述了适用于分布式智能电网的新理论与方法。从物理层、信息层、价值层3个层面分析了分布式智能电网的技术发展方向,探索了分布式智能电网的技术体系。
The Distributed Smart Grid(DSG)is crucial in constructing new power systems in the background of carbon peaking and carbon neutrality goals.It is essential for advancing new power systems towards clean,low-carbon,safe,sufficient,economical,efficient,coordinated supply and demand,and flexible,intelligent operations.This paper synthesizes the current domestic and international development status,analyzes the development trends and new characteristics of generation,grid,load,and storage in new power systems,and summarizes the challenges brought by new development trends that the DSG needs to overcome.Subsequently,the paper outlines the connotation of the DSG and elaborates on its technical characteristics.The core lies in the intelligent reconfiguration of the existing power grid,and it specifically discusses the organizational structure,grid framework,and control architecture of the DSG.Furthermore,the paper summarizes the theoretical framework of the DSG from three levels:distributed unit modeling and coordination,distributed cluster division and interaction,and distributed power grid optimization and control,and expounds new theories applicable to the DSG.It also explores the technical development directions of the DSG from three layers:physical,information,and value,forming a technological framework for the DSG.
