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…
Rethinking Frequency Control in Power Systems
Taulant Kerci, Angel Vaca, Andrew Groom +2
Frequency control in power systems is implemented in a hierarchical structure traditionally known as primary frequency control (PFC), secondary frequency control (SFC) and tertiary…
Decentralized Approach to Detect and Eliminate Flapping Phenomena due to Flexible Resources
Angel Vaca, Federico Milano
This paper presents a decentralized methodology for detecting and mitigating flapping phenomena in power systems, primarily caused by the operation of discrete devices. The propose…
Impact of Power Fluctuations on Frequency Quality
Angel Vaca, Federico Milano
This paper analyzes how power injections affect frequency quality in power systems. We first derive a general expression linking active and reactive power injections at buses to th…
Synthetic Discrete Inertia
A. Vaca, F. Milano
This letter demonstrates how synthetic inertia can be obtained with the control of flexible discrete devices to keep the power balance of power systems, even if the system does not…
