The construction of new power system with low carbon and high efficiency has brought new challenges to all links of source-grid-load-storage (SGLS). Facing the operation requirements of power system under the new situation

a SGLS architecture based on 5G+ cloud-edge-terminal cooperation and its key technologies are proposed. Firstly

by analyzing the technical characteristics of source

grid

load and storage in new power system

its main changes and characteristics are clarified. Furthermore

the technical concept of 5G+ cloud-edge-terminal cooperation is proposed

which organically combines with the original information technologies

and a technical support platform with vertical connection and horizontal interconnection is constructed. Through its application to SGLS collaborative operation of new power system

the connected chain relationship of power grid between source

grid and load is expanded into a multi-dimensional-network relationship with horizontally connection and vertically cloud-pipe-edge-terminal extension in various fields

which overcomes the limitations of traditional source-grid-load technology. Finally

the key technologies under the proposed architecture are analyzed to clarify the development requirements of SGLS technology of 5G+ cloud-edge-terminal cooperation in new power system

so as to provide a reference for subsequent technology promotion.
