Recent recovery of surface wind speed in northwest China
International Journal of Climatology, 2018Previous studies have reported that much of the surface wind speed (SWS) over the mid‐latitudes of the northern hemisphere has declined. However, very few studies have investigated the relatively recent phenomenon of wind recovery.

Extreme wind speeds in mixed wind climates
Journal of Wind Engineering and Industrial Aerodynamics, 1978Abstract In this paper, a technique is discussed which enables extreme wind speed probabilities in mixed wind climates to be determined. It is shown that in such wind climates the method is likely to yield more accurate probability estimates than the traditional Gumbel analysis of annual wind speed maxima, particularly for annual probabilities of ...

Wind speed and wind energy potential of Jordan
Solar Energy, 1987Abstract Routine wind data from 11 stations in Jordan have been analysed. Monthly average, and seasonal wind speed and average power density distributions were determined for each station. The monthly average wind speed for the two most potential sites Ras Muneef (RA) and Mafraq (MF) ranged from 3.0 to 7.4 m/sec and the average power density for ...

Research of Wind Speed and Wind Power Forecasting
Advanced Materials Research, 2011Wind power has entered a rapid progress stage. Due to the intermittency of wind energy and the non-linearity of power system, there exist many uncertain variables which should be considered in the wind power prediction. Accurate wind power forecastings are beneficial for wind plant operators, utility operators, and utility customers.

Influence of Wind Speed on Wind Turbine Reliability
Wind Engineering, 2006Wind turbines have been erected in increasing numbers in Europe, the USA and elsewhere. In Europe Denmark has played a particularly prominent part in developing the technology and has installed a large numbers of turbines. The paper is concerned with the influence of the weather on the reliability of modern wind turbines and in particular the effect ...

Virtual Wind Speed Sensor for Wind Turbines
Journal of Energy Engineering, 2011A data-driven approach for development of a virtual wind-speed sensor for wind turbines is presented. The virtual wind-speed sensor is built from historical wind-farm data by data-mining algorithms. Four different data-mining algorithms are used to develop models using wind-speed data collected by anemometers of various wind turbines on a wind farm ...

Bidding Wind Energy Exploiting Wind Speed Forecasts
IEEE Transactions on Power Systems, 2016In this paper, we address the problem of determining the optimal day-ahead generation profile for a wind power producer by exploiting wind speed forecasts provided by a meteorological service. In the considered framework, the wind power producer is called to take part in the responsibility of system operation by providing day-ahead generation profiles ...

Wind Turbine Torque and Wind Speed Estimation
ASME 2011 Dynamic Systems and Control Conference and Bath/ASME Symposium on Fluid Power and Motion Control, Volume 1, 2011An adaptive-observer to estimate both the parameters of a new model of the mechanical torque in a wind turbine and the wind velocity is proposed. The model is based in a relative velocity between the wind speed and blades of turbine. Results of torque estimation are compared with those obtained from a heuristic model, commonly used in the literature ...
