Abstract: It is urgent to accelerate energy power technology innovation for promoting global energy interconnection(GEI). Five important areas are proposed for GEI technology innovation, including large-capacity long-distance transmission, large-power grid safe operation and control, new energy power generation and integration, advanced energy storage, and internet information and communication. An analysis is made on the each area’s key technologies that have important supporting impacts on GEI, and the focus of research, their future development trend and application prospects.

Key words: global energy interconnection, technology innovation, five important field, application prospect
