In order to investigate the power system impact of wind turbines, it is essential to use accurate simulation models of wind turbines and power system. These models must correctly represent the electromagnetic and electromechanical behavior of the wind turbines in order to predict critical operational conditions and grid reinforcements. Power system elements such as busbars, lines, cables, etc. ...

The growing trend of wind generation in power systems and its uncertain nature have recently highlighted the importance of wind power prediction. In this paper a new wind power prediction approach is proposed which includes an improved version of Kriging Interpolation Method (KIM), Empirical Mode Decomposition (EMD), an information-theoretic feature selection method, and a closed-loop forecasti...

Power Generation from Renewable energy sources like wind, solar, geothermal, biomass, and hydro is predominant now days and among the renewable energy sources, small hydro and wind energy have the ability to complement each other. For Power generation by small or micro hydro as well as wind systems, the use of squirrel-cage induction generators (SCIGs) is mostly adopted. As regards in recent ye...

abstract wind erosion of soils and suspended particles in iran is one of the serious environmental and agricultural problems which affect agricultural lands, water reservoirs, irrigation canals, drains and etc. therefore wind erosion control needs attention specially in arid and semi-arid regions. although in recent years, some polymeric materials have been used for improvement of structural st...

The use of offshore wind farms has been growing in recent years, as steadier and higher wind speeds can be generally found over water compared to land. Moreover, as human activities tend to complicate the construction of land wind farms, offshore locations, which can be found more easily near densely populated areas, can be seen as an attractive choice. However, the cost of an offshore wind far...

It is important to improve the accuracy of wind speed forecasting for wind parks management and wind power utilization. In this paper, a novel hybrid approach known as WTT-TNN is proposed for wind speed forecasting. In the first step of the approach, a wavelet transform technique (WTT) is used to decompose wind speed into an approximate scale and several detailed scales. In the second step, a t...

[1] The primary goal of this paper is to provide estimates of upstream solar wind plasma conditions at Mercury during the January 2008 MESSENGER flyby, based on two completely independent solar wind models. The first is a steady-state three-dimensional (3-D) magnetohydrodynamic (MHD) model of the solar corona and inner heliosphere, which simulates the solar wind propagation from the source surf...

The residents of Mexico City face serious problems of air pollution. Identifying the most representative scenarios for the transport and dispersion of air pollutants requires the knowledge of the main wind circulation patterns. In this paper, a simple method to recognize and characterize the wind circulation patterns in a given region is proposed and applied to the Mexico City winds (2001–2006)...
