Sinusoidality Index
J. Gutiérrez Florensa, L. Sigrist, Ã. Ortega +1
Maintaining sinusoidal or near-sinusoidal operating conditions in electrical systems is essential, as is their accurate assessment. This letter proposes a novel metric, namely the…
Instantaneous Frequency in Power Systems using the Teager-Kaiser Energy Operator
A. Vaca, J. Gutierrez Florensa, F. Milano
This letter develops an instantaneous-frequency (IF) local estimator calculated with the complex Teager-Kaiser energy operator (CTKEO) and the dynamic-signal identity. The contribu…
Theoretical and Experimental Limitations of RoCoF Estimation
Gutierrez-Florensa, F. Sanniti, D. Tedeschi +3
A precise estimation of the Rate of Change of Frequency (RoCoF) is crucial for secure power system operation. In fact, RoCoF is strictly related to the amount of the available phys…
Quasi Steady-State Frequency
Joan Gutierrez-Florensa, Alvaro Ortega, Lukas Sigrist +1
Accurate frequency estimation is critical for the control, monitoring and protection of electrical power systems, in particular, of systems with a high penetration of power electro…
