An Integrated 5G-IoT Architecture in Smart Grid Wide-Area Monitoring, Protection, and Control

It was found that smart grid places real and diverse challenges on new 5G network technologies. On the one hand, power grids represent one of key critical infrastructures, and its planning and operation should be done considering a number of aspects. To enable optimal operation of power grids, particularly optimal integration of renewable energy sources, implementation of novel sensor and communication infrastructure is mandatory. We are very keen to provide a detailed discussion on needs, opportunities, and challenges related to the application of 5G and IoT technologies in modern power systems, power systems with high penetration of renewable energy resources, and systems with significantly changed dynamics and expectations. Examples of the following high-impact practical projects, in which the first author of the chapter acted as PI on behalf of academia, will be presented: VISOR, EFCC, Supergen Multi-Energy Networks, Hub and MIGRATE projects. This chapter is organized as follows. In the first part, we will investigate requirements and symbiotic relationship between two of the modes in 5G, namely massive machine-type communications (mMTC) and ultrareliable low-latency communications (uRLLC) and the smart grid communication, which are essential to apply IoT. In the second part, we emphasize the unification of standardization efforts to avoid deployment issues such as interoperability. In the third part, we present high-impact practical projects and 5G-IoT integration issues in future smart grid application scenarios.
