Abstract: The extensive application of advanced information technology in smart power distribution and utilization system(SPDUS) deepens the coupling degree between the information side of the system and the power physical side. Smart power distribution systems have been gradually transformed into smart power distribution and utilization cyber physical system(SPDU-CPS) with a high degree of integration of information-physical space. The research status at home and abroad from three perspectives of SPDU-CPS network attack intrusion detection, network attack defense and protection, and self-healing control is summarized and prospected. In the aspect of network attack intrusion detection, the detection ideas and implementation paths of network attack detection methods based on deviation class, feature class and hybrid class are summarized. In the aspect of network attack defense and protection, the information side protection method, the physical side protection method based on resource optimization allocation and data correction protection and the information physical cooperative protection method combining the information and protection functions of both sides are introduced. In the aspect of self-healing control, the existing researches on the traditional power physics self-healing control and the self-healing control based on information physics coordination are summarized and sorted out. Finally, the future research direction is prospected.
