Objective The information-physical fusion characteristics of the novel power system pose new requirements for cybersecurity protection, including whole-domain synergy and dynamic adaptation, and also bring severe core challenges to cybersecurity. This article aims to comprehensively sort out the current status and key technologies of the novel power system in the cybersecurity environment, and explore the application prospects of its cybersecurity protection.

Method Based on policy documents and engineering cases, the current status of cybersecurity of the novel power system was analyzed from multiple dimensions; the research progress of key technologies such as intelligent threat detection, data encryption and emergency response was summarized; and typical cybersecurity application scenarios of the novel power system, such as the physical information domain, network data layer and system layer were sorted out.

Result It clarifies the bottlenecks of existing technologies in addressing new attack methods, as well as their potential threats and application limitations to the power system.

Conclusion It provides a theoretical basis for theoretical research, standard development and engineering implementation in the field of novel power system cybersecurity, as well as for breaking through current protection bottlenecks. It proposes that in the future, focus should be placed on breaking through the information-physical-social synergistic protection model to achieve the security goal of "measurable, controllable and traceable".
