  The fifth-generation mobile communication (5G) technology offers
opportunities to enhance the real-time monitoring of grids. The 5G-enabled
phasor measurement units (PMUs) feature flexible positioning and cost-effective
long-term maintenance without the constraints of fixing wires. This paper is
the first to demonstrate the applicability of 5G in PMU communication, and the
experiment was carried out at Verizon non-standalone test-bed at Pacific
Northwest National Laboratory (PNNL) Advanced Wireless Communication lab. The
performance of the 5G-enabled PMU communication setup is reviewed and discussed
in this paper, and a generalized dynamic linear model (GDLM) based real-time
synchrophasor data anomaly detection use-case is presented. Last but not least,
the practicability of implementing 5G for wide-area protection strategies is
explored and discussed by analyzing the experimental results.
