A simplified electro-mechanical model of a DFIG-based wind turbine for primary frequency control studies
(2016)
In recent years, world-wide power systems are experiencing a steadily growth of wind power penetration. A common concern in the operation of such systems is related to the frequency stability. Modern variable speed wind ...
Fast-frequency response provided by DFIG-wind turbines and its impact on the grid
(2017)
This paper presents a methodology for the analysis of frequency dynamics in large-scale power systems with high level of wind energy penetration by means of a simplified model for DFIG-based wind turbines. In addition, a ...

Evaluation of primary stability in modified implants: Analysis by resonance frequency and insertion torque
(2018-06-01)
Background: Changes in the macrogeometry of dental implants are known to influence primary stability and the osseointegration process. Purpose: The purpose of the present in vitro study was to evaluate the mechanical ...
Primary Frequency Control of Multi-Machine Power Systems with STATCOM-SMES: A Case Study
(Elsevier, 2013-01)
Primary frequency control (PFC) has the ability to regulate short period random variations of frequency during normal operation conditions and response to emergency rapidly. However, in the last decade, many large blackouts ...
Analysis of control strategies based on virtual inertia for the improvement of frequency stability in an islanded grid with wind generators and battery energy storage systems
(2021)
Rising levels of non-synchronous generation in power systems are leading to increasing difficulties in primary frequency control. In response, there has been much research effort aimed at providing individual electronic ...
Unit Commitment with Primary Frequency Control Requirements for Low-Inertia Systems
(2018)
As we move towards power systems with less inertia, frequency excursions from under-frequency contingencies become more extreme and require scheduling more spinning reserves. This paper proposes an algorithm to include ...
Use of battery energy storage systems to enhance the frequency stability of an islanded microgrid based on hybrid photovoltaic-diesel generation
(Springer Science and Business Media Deutschland GmbH, 2021)
Primary frequency control in power systems is becoming more difficult as levels of non-synchronous generation grow. This paper explores how implementing a control strategy based on the concept of virtual inertia, supported ...
Determinación de la Respuesta Dinámica y Estacionaria de la Frecuencia frente a Desbalances de Potencia Producidos por Perturbaciones en la Red
(CENACE, 2016-01)
This paper proposes a new methodology for determining the transient and steady state frequency deviations produced by disturbances in the power system that modify the generation-load balance. Based on the equivalent frequency ...
