Smart grid requires high-speed and reliable communication to enable real-time monitoring through Internet of Things devices.5G can be seen as a catalyst for transforming the current power grid infrastructure into a smart grid.Therefore

understanding the advantages of 5G in terms of network security in IoT-based smart grids is crucial for design decisions and future risk analysis.This paper explores a use case of intelligent power grid with automated voltage control

utilizing 5G as a wireless communication infrastructure with edge support.It identifies the advantages of 5G in several security aspects and demonstrates how 5G security technologies can be applied to smart grids

providing a foundation for the security analysis of future 5G smart grid systems.
