What is frequency regulation in power system?Frequency regulation in power system In power systems, frequency is the continuously changing variable which is influenced by the power generation and demand. A generation deficit results in frequency reduction while surplus generation causes an increase in the frequency.
When is a frequency regulation strategy inactive?This strategy is inactive when the system frequency remains within a predetermined frequency deviation threshold, whereby only the primary frequency regulation is executed through a combination of virtual droop and virtual inertia.
Why is disengagement from secondary frequency regulation important?Disengagement from the secondary frequency regulation not only accelerates the restoration of grid frequency but also ensures precise and error-free adjustment of the system frequency, thereby improving tracking and dynamic performance. The effectiveness of the proposed control strategy is demonstrated through simulation.
What is dynamic frequency support hybrid storage?Dynamic frequency support requires continuous charging/discharging which involves partial charge/discharge events (detrimental to BES life).
