|The integration of renewable energy sources in the electrical grid imposes several operational issues for the energy markets and the transmission system operators, in particular. It is of great importance not only to detect events, but also to react in time to prevent faults in the transmission system that could lead to outages for the consumers or even to permanent damage to the energy equipment. Towards this scope, the criticality of the role of the Phasor Measurement Units (PMUs) which provide readings of voltage, frequency and current, is explained in this paper. It is also discussed how the 5G network may assist in the transfer of the measurements with its low latency capabilities and high availability criteria. Based on a Smart5Grid project’s dedicated use case, the concept of 5G enhanced wide area monitoring is presented along with the associated field platform implementations both in Greece and Bulgaria. A complete list of defined Field Platform Validation Metrics is also elaborated with the equivalent targeted values.
