The Output power of wind turbine is determined by wind speed. The Output power can be adjusted by controlling the generator speed and pitch angle of wind turbine. When the wind speed below the wind turbine rated, the output power of generator can be maximized by controlling the generator speed at point of maximum power coefficient. When the wind speed above the wind turbine rated, output power ...

A theoretical model that describes the power of a scattered Global Positioning System (GPS) signal as a function of geometrical and environmental parameters has been developed. This model is based on a bistatic radar equation derived using the geometric optics limit of the Kirchhoff approximation. The waveform (i.e., the time-delayed power obtained in the delay-mapping technique) depends on a w...

The fluctuation of active power output of wind farm has many negative impacts on large-scale wind power integration into power grid. In this paper, flywheel energy storage system (FESS) was connected to AC side of the doubly-fed induction generator (DFIG) wind farm to realize smooth control of wind power output. Based on improved wind power prediction algorithm and wind speed-power curve modeli...

Efficient extraction of renewable energy from wind depends on the reliable estimation characteristics and optimization farm installation operation conditions. There exists uncertainty in prediction tapping potential based variability behavior. Thus power density empirical models demand subsequent data processing to ensure accuracy reliability computations. Present study analyses ANN-based machi...

In wind energy industry, power curve, the plot of the generated power versus the ambient wind speed, is an important indicator of the performance and health of wind turbines. The nominal power curves differ by manufacturers and types. The actual power curve will deviate from the nominal one because of the turbulence in the incoming wind, turbine health, etc. Power curve is widely used for visua...

In this theoretical investigation, a hybrid power generation system utilizing wind energy and hydrogen storage is presented. Firstly, the available wind energy is determined, which is followed by evaluating the e$ciency of the wind energy conversion system. A revised model of windmill is proposed from which wind power density and electric power output are determined. When the load demand is les...
