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 ...
Statistical analysis of discontinuities in solar wind ace data and comparison with intermittent mhd turbulence
(IOP Publishing, 2009-12)
The comparison between Advanced Composition Explorer (ACE) solar wind data and simulations of magnetohydrodynamic (MHD) turbulence shows a good agreement in the waiting-time analysis of magnetic field increments. Similarity ...
Multi-parameter bifurcation analysis of subsynchronous interactions in DFIG-based wind farms
(Elsevier Science Sa, 2016-11)
This work analyzes the dynamics involved in subsynchronous interactions between wind farms and series-compensated transmission lines. This adverse phenomenon may arise when doubly-fed induction generators are radially ...

Estudo de caso: análise dinâmica linear de uma torre de concreto armado usando modelos de massa concentrada e análise modal
(Universidade Tecnológica Federal do ParanáToledoBrasilEngenharia CivilUTFPR, 2019-06-06)
A dynamic analysis has great importance in structural analysis field because considers the effects caused by momentary efforts in the structure, these efforts could be caused by different ways and cause vibrations in the ...
Development of hybrid steel-commingled composites CF/PEEK/BwM by filament winding and thermoforming
(2022-02-08)
A hybrid material made of carbon fiber, poly(ether-ether-ketone) and metallic braided wire mesh was designed to improve the crashworthiness of thermoplastic composite structures. The filament winding process was adapted ...
Subsynchronous interactions in power networks with multiple DFIG-based wind farms
(Elsevier Science Sa, 2018-12)
This paper exposes relevant characteristics of the stability boundary associated to subsynchronous control interactions when multiple DFIG-based wind farms are radially connected to a series compensated transmission line. ...
A Review on the Estimation of Power Loss Due to Icing in Wind Turbines
(MDPI, 2022-02)
The objective of this article is to review the methodologies used in the last 15 years to
estimate the power loss in wind turbines due to their exposure to adverse meteorological conditions.
Among the methods, the use ...
Statistical downscaling of sea-surface wind over the Peru–Chile upwelling region: diagnosing the impact of climate change from the IPSL-CM4 model
(Springer, 2011-04)
The key aspect of the ocean circulation off Peru–Chile is the wind-driven upwelling of deep, cold, nutrient-rich waters that promote a rich marine ecosystem. It has been suggested that global warming may be associated with ...
