Experimental Evaluation of a Virtualized 5G Core for Smart Grid Applications

• 5G with its great capabilities is believed to play a crucial role in different vertical sectors such as automotive, healthcare, and energy, etc. In this paper, we present a study on the adoption of 5G into a smart grid environment, in particular, a power grid substation automation system. In such a system, the communication between electrical devices is often within a few milliseconds. To verify the proposed solution, we conducted a set of experiments using the Generic Object Oriented Substation Event (GOOSE) protocol, a standard protocol used in power grid substation automation systems, over a virtualized 5G network. 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.
