为探究韧性电网信息物理融合系统风险研究现状及发展趋势,基于中国知网(CNKI)和Web of Science(WoS)数据库2011-2023 年的文献数据,利用CiteSpace对该领域研究的研究热点、前沿及演化趋势进行可视化分析.研究结果表明:国内研究形成以"风险预警与控制"和"电力系统智能化建设"为主题的研究热点,国外研究形成以"信息物理融合"和"连锁故障演化"为主题的研究热点;"智能电网的信息物理耦合"和"信息网络攻击风险分析"是国内研究的前沿方向,"信息物理融合系统安全状态估计"和"风险防控模型"是国外研究的前沿方向;国内研究可分为安全性理论研究期、信息物理攻击风险研究期和故障防御恢复研究期3 个时间阶段,国外研究可分为信息物理融合研究期和信息物理安全应用期2 个时间阶段;后续研究应加强改进电力信息物理融合系统建模、完善电力信息物理融合系统规划、推进电力信息物理融合系统应用,推进数字化韧性电网稳定运行.研究结果可为韧性电网风险识别和风险预警研究提供一定参考.
To explore the current status and development trend of the risk research on cyber-physical systems of resilient pow-er grids,based on the literature data from China national knowledge network(CNKI)and Web of Science(WoS)databases from 2011 to 2023,the CiteSpace was used to visualize and analyze the research hotspots,frontiers and evolutionary trends of research in this field.The results show that the research hotspots of"risk warning and control"and"intelligent construction of power system"have been formed in China,and the research hotspots of"cyber-physical fusion"and"cascading failure evolution"have been formed at abroad.The"cyber-physical coupling of smart power grid"and"information network attack risk analysis"were the research frontiers in China,and the"cyber-physical system security state estimation"and"risk pre-vention and control model"were the research frontiers at abroad.The research in China could be divided into three time pha-ses:security theory research period,cyber-physical attack risk research period,and failure defense recovery research period,and the research at abroad could be divided into two time phases:cyber-physical fusion research period and cyber-physical security application period.The follow-up research should strengthen the improvement of power cyber-physical system model-ing,improve the planning of power cyber-physical system,promote the application of power cyber-physical system,and pro-mote the stable operation of digital resilient power grid.The research results can provide some reference for the risk identifica-tion and risk warning research of resilient power grid.
