A Research on Primary Frequency Control Strategy

DEStech Transactions on Engineering and Technology Research, 2017
There are the overshoot phenomena of the active power regulation in some regions, which goes against the reliability and the economics of the power system. The Strategy of primary frequency control is not reasonable for regulation. The influence of current primary frequency control strategy is discussed. A new strategy considering cooperation of AGC is

Fast Frequency Support From Wind Turbine Systems by Arresting Frequency Nadir Close to Settling Frequency

IEEE Open Access Journal of Power and Energy, 2020
The recent power cut incident in the UK on 9th August 2019 indicated that frequency control to raise frequency nadir and eliminate frequency second dip is highly desirable for power grids with high penetration of wind energy.

Repetition enhancement for frequency-modulated but not unmodulated sounds: a human MEG study [PDF]

, 2010
Background: Decoding of frequency-modulated (FM) sounds is essential for phoneme identification. This study investigates selectivity to FM direction in the human auditory system.

Primary frequency response based rescheduling for enhancing microgrid resilience

Journal of Modern Power Systems and Clean Energy, 2019
The existing microgrid operation schemes do not consider the dynamic performance of frequency in the islanded operation of microgrids. When an islanded microgrid encounters a disturbance, the sudden power mismatch could impose security risks or even a ...
