Synchrophasor-Based ROCOF Measurements: Feasibility in Real-World Scenarios

Mario Paolone, Asja Derviskadic, Guglielmo Frigo

In modern power systems, Rate of Change of Frequency (ROCOF) is employed in monitoring and control applications. However, a standard approach towards ROCOF measurements is still missing. In this paper, we investigate the feasibility of Phasor Measurement U ...
