Title
On the Use of a Virtualized 5G Core for Time Critical Communication in Smart Grid
Abstract
Protection and automation in a smart grid environment often have stringent real-time communication requirements between devices within a substation, as well as between distantly located substations. The Generic Object Oriented Substation Event (GOOSE) protocol has been proposed to achieve this goal as it allows to transfer time-critical information within a few milliseconds. However, the transmission of GOOSE messages is often limited to a small Local Area Network (LAN). An earlier work has proposed to use the fifth generation of mobile networks (5G) as a means to transport IP-based GOOSE messages in a large-scale smart grid environment. On the basis of this work, this paper designs and implements an alternative solution for Ethernet-based GOOSE communication over a virtualized 5G core network that does not require any modification of the existing network protocol stack and thus is much easier to deploy. Our experimental results show that the delay introduced by the core network is in the order of sub milliseconds, while the one-way delay without a real radio access network, and without background traffic, is less than 1 ms. Moreover, these delays can be significantly reduced with a container-based deployment rather than a virtual machine-based one. Assuming a 1-ms delay budget for a 5G radio access network, our evaluation confirms that it is indeed feasible to use 5G for GOOSE transmission in IEC 61850 substation automation systems.
