Optimized Power Distribution Technology for Fast Frequency Response in Photovoltaic Power Stations

Energies, 2022
The fast frequency response (FFR) function in renewable energy source (RES)-based power stations has proved to be able to improve the frequency stability of power systems with high RES penetration significantly.

Multi‐objective optimal provision of fast frequency response from EV clusters [PDF]

IET Generation, Transmission & Distribution, 2020
Declining levels of rotational inertia in modern power systems prompt transmission system operators (TSOs) to develop novel ways of maintaining the balance between generation and demand. Services such as fast frequency response (FFR) can help the TSO achieve this balance.

Pulsatile Hormonal Signaling to Extracellular Signal-Regulated Kinase: Exploring System Sensitivity to Gonadotropin-Releasing Hormone Pulse Frequency and Width [PDF]

, 2014
Gonadotropin-releasing hormone (GnRH) is secreted in brief pulses that stimulate synthesis and secretion of pituitary gonadotropin hormones and thereby mediate control of reproduction.

Quantitative Control Approach for Wind Turbine Generators to Provide Fast Frequency Response with Guarantee of Rotor Security

, 2017
Wind generation is expected to reach substantially higher levels of penetration in the near future. With the converter interface, the rotor inertia of doubly-fed induction generator (DFIG) based wind turbine generator is effectively decoupled from the ...

Synthetic inertia versus fast frequency response: a definition

IET Renewable Power Generation, 2017
This study discusses synthetic inertia from the perspective of a transmission system operator and compares it to fast frequency response based on frequency deviation. A clear distinction of the meanings between these concepts is discussed, the basis of which is a description of their characteristics.

A Fast Frequency-Domain Algorithm for Equalizing Acoustic Impulse Responses

IEEE Signal Processing Letters, 2012
The multiple-input/output inverse theorem (MINT) algorithm for multichannel equalization is computationally demanding. Although adaptive MINT reduces the computational complexity, it suffers from slow convergence. In this letter, we propose a low-complexity fast-converging adaptive algorithm for multichannel equalization.

A unified framework for co-optimization of PFR and FFR reserves using linearized tri-criteria frequency constraints

International Journal of Electrical Power & Energy Systems
The increasing penetration of inverter-based resources reduces system inertia and heightens concerns about frequency stability. This paper proposes a systematic methodology for jointly optimizing primary frequency response (PFR) and fast frequency ...
