Abstract: With the in-depth advancement of the new power system,acquisition control gradually extends and sinks to the power distribution and consumption side,and the source-network-load-storage links are more closely connected,and massive data needs to be aggregated in real-time and processed efficiently.This put forwards higher requirements for network coverage,service carrying,convenient access,security and controllability,and standard management of the terminal communication network.Given this situation,we propose an optimization plan for the coverage,service carrying capacity,flexibility and convenience,and technical security of the terminal communication network and build a terminal communication network with full network coverage,comprehensive business support,efficient terminal access,and technology security and controllable.It can comprehensively meet the communication access needs of various power services,and improve the network carrying capacity,service support capacity,and resource utilization rate.It also improves the security,reliability,economic applicability,and scientific management of the terminal communication network,provides an important basic guarantee for the construction of the new power system digital technology support system,and serves the construction of energy internet.
