Benefits of demand-side response in providing frequency response service in the future GB power system [PDF]

open access: yes, 2015
The demand for ancillary service is expected to increase significantly in the future Great Britain (GB) electricity system due to high penetration of wind.

Research on Robust Day-Ahead Dispatch Considering Primary Frequency Response of Wind Turbine

open access: yesApplied Sciences, 2019
With the large-scale integration of renewable energy sources (e.g., wind power), the system inertial response and primary frequency regulation are affected.

Ancillary Services Market Design in Distribution Networks: Review and Identification of Barriers

open access: yesEnergies, 2020
The high proliferation of converter-dominated Distributed Renewable Energy Sources (DRESs) at the distribution grid level has gradually replaced the conventional synchronous generators (SGs) of the transmission system, resulting in emerging stability and

Spectral and temporal processing in human auditory cortex [PDF]

open access: yes, 2002
Hierarchical processing suggests that spectrally and temporally complex stimuli will evoke more activation than do simple stimuli, particularly in non-primary auditory fields.

Engineering inertial and primary-frequency response for distributed energy resources [PDF]

open access: yes2017 IEEE 56th Annual Conference on Decision and Control (CDC), 2017
We propose a framework to engineer synthetic-inertia and droop-control parameters for distributed energy resources (DERs) so that the system frequency in a network composed of DERs and synchronous generators conforms to prescribed transient and steady-state performance specifications.

A fisheries acoustic multi-frequency indicator to inform on large scale spatial patterns of aquatic pelagic ecosystems [PDF]

open access: yes, 2013
Fisheries acoustic instruments provide information on four major groups in aquatic ecosystems: fish with and without swim bladder (tertiary and quaternary consumers), fluidlike zooplankton (secondary consumers) and small gas bearing organisms such as ...

An extended modeling of frequency security constraints for unit commitment model

open access: yesEnergy Reports, 2023
Under the background of high proportion of renewable energy, the frequency security of the power system is facing challenges, which makes it necessary to consider and respond in the optimal dispatching. In this paper, the frequency security constraint is

Influence of wind turbine inertia support on frequency drop characteristics of power grid

open access: yesZhejiang dianli, 2023
With the increasing penetration of new energy sources in large synchronous grids, renewable generator units that do not have inertial response capability may undermine the inertia of the system.

The Standing Wave Phenomenon in Radio Telescopes; Frequency Modulation of the WSRT Primary Beam [PDF]

open access: yes, 2007
Inadequacies in the knowledge of the primary beam response of current interferometric arrays often form a limitation to the image fidelity. We hope to overcome these limitations by constructing a frequency-resolved, full-polarization empirical model for ...

The additional control strategies to improve primary frequency response for hybrid power plant with gas turbines and steam turbines

open access: yesEnergy Reports, 2022
Gas turbines with fast response characteristics make it possible to improve the flexibility of grid regulation. However, there are still some challenges in the connection of gas turbines.
