SOLAR WIND MAGNETIC FLUCTUATIONS and ELECTRON NON-THERMAL TEMPERATURE ANISOTROPY: SURVEY of WIND-SWE-VEIS OBSERVATIONS
(Institute of Physics Publishing, 2016)
© 2016. The American Astronomical Society. All rights reserved. The solar wind electron velocity distribution function (eVDF) exhibits a variety of non-thermal features that deviate from thermal equilibrium. These deviations ...
Dynamics and Stability Analysis of a Power System With a PMSG-Based Wind Farm Performing Ancillary Services
(Institute of Electrical and Electronics Engineers, 2014-07)
This work studies the impact on power system dynamics of wind energy conversion systems based on permanent magnet synchronous generators when they perform ancillary services. The ability of modern variable-speed wind ...
Wind Power Curtailment and Energy Storage in Transmission Congestion Management Considering Power Plants Ramp Rates
The integration of intermittent generation in power grids, such as wind energy, imposes new challenges for transmission congestion management. In order to solve this problem, energy storage systems (ESS) have been proposed ...
A composite beam finite element for multibody dynamics: Application to large wind turbine modeling
This work presents a beam finite element with multibody capabilities for modeling high aspect ratio composite wind turbine components, particularly the tower and the blades. The proposed formulation is based on an Updated ...
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 ...
Análise espaço-temporal dos ventos no extremo norte da Planície Costeira do Rio Grande do Sul, BrasilSpatial-temporal analysis of the winds in the extreme north of Rio Grande do Sul Coastal Plain, Brazil
(Instituto de Geociências /Universidade Federal do Rio Grande do Sul, 2017)
INSTALLATION OF WIND POWER AND ESTIMATIVE OF ENVIRONMENTAL LOSSES IN A SECTOR OF THE WEST COAST OF CEARA, BRAZIL
(Univ Federal Ceara, Programa Pos-graduacao & Filosofia, 2015-10-01)
Brazil, which relies on hydroelectric power, has developed other sources of renewable energy, mainly wind power. The state of Cear, in the northeastern region, has a potential wind power of 26.2 GW; however, this form of ...
