摘　　要：配电网数字化转型将进一步促进信息系统与物理系统的深度耦合,由于配电网信息安全防御资源有限,难以将信息侧安全风险隔离于物理系统之外,这也使得配电网状态估计正面临全新的挑战。首先,文中简要介绍了配电网信息物理系统体系结构,并构建了面向信息物理系统的配电网状态估计技术框架;其次,较为全面地梳理了信息物理融合背景下配电网状态估计技术的国内外研究现状,包括考虑网络攻击的配电网伪量测建模与分析、配电网虚假数据注入攻击分析与防御以及配电网信息物理系统安全风险分析与可靠性评估等方向;最后,对该领域未来进一步发展所面临的关键问题进行了探讨和分析。The digital transformation of distribution networks will further promote the deep coupling of information system and physical systems.Due to the limited information security defense resources of the distribution network,it is difficult to isolate the security risks of the information side from the physical system,which also makes the state estimation of the distribution network face new challenges.Firstly,the architecture of the distribution network cyber-physical system is briefly introduced,and the technical framework of the distribution network state estimation for cyber-physical system is constructed.Secondly,this paper comprehensively reviews the research status of distribution network state estimation technologies at home and abroad on the background of cyber-physical fusion,including the pseudo-measurement modeling and analysis of distribution networks considering cyber-attacks,the analysis and defense of false data injection attacks in the distribution network,and the security risk analysis and reliability assessment of distribution network cyber-physical systems.Finally,the key problems facing the further development of this field are discussed and analyzed.
