Digitalization and intellectualization are major trends in development of power system asset management. Based on recent research results of asset management and risk assessment of International Council on Electricity Distribution(CIRED), first of all, recent development status of the key technologies in power grid asset management is illustrated, including state evaluation, reliability and risk assessment, and life cycle cost(LCC) analysis. Theoretical methods and application status of these three key technologies in asset management are presented. Secondly, present application situation of digital technologies represented by information and communication technology and big data technology is summarized. Support function of digital technologies for asset management process and its key technologies are analyzed. Then future development trends and challenges of each digital technology applied in power grid asset management are expounded. Based on this, this paper puts forward some suggestions for power grid asset management in China, to provide a useful reference from technical level for improvement of China's power grid asset management.
