An Analysis of 5G D2D Network in Power Grids’ Automation

Abstract

Traditional ad-hoc is infrastructure-less. UEs (User Equipment) can realize rapid networking, but cannot guarantee the reliability of D2D (Device to Device) connection. 5G provides a network infrastructure of reliable connection, based on this, D2D provides visualized connection i.e. an autonomously controllable "virtualization ad-hoc". In order to integration of 5G D2D (ie. DCE) with DTE (Data terminal equipment) in power grids’ automation control and protection in the field area, dual-plane redundancy in substation and heterogeneous hand in hand connection in distribution power lines are proposed. Cross-layer connection failure detection and autonomous maintenance are further discussed. The applicable test shows the method can significantly improve the reliability of the power grids’ D2D network.
