Optimal Design of a Wide Area Measurement System Using Hybrid Wireless Sensors and Phasor Measurement Units [PDF]

, 2019
Real-time monitoring of the power system by phasor measurement units (PMUs) leads to the development of such devices in a wide area measurement system (WAMS). However, the power system observability cannot be obtained by employing only PMUs.
