Relationship between wind-exposed area and power generation

What factors affect the power generated by a wind turbine?

Also, a mathematical model is presented for wind power & investigates the influence of such parameters on the electrical power generated by the wind turbine. The considered factors are wind speed, turbine swept area, air density, weather temperature, and height of tower.

Does wind speed affect power generation?

Many research studies illustrate the influence of wind speed on the turbine at a flat terrain site. The results show that wind turbines heavily depend upon atmospheric conditions, and consequently, power generation increases with the increase in the wind speed at the hub height .

Why is wind power generation important?

Another contribution of wind power generation is that it allows countries to diversify their energy mix, which is especially important in countries where hydropower is a large component. The expansion of wind power generation requires a robust understanding of its variability and thus how to reduce uncertainties associated with wind power output.

How much power does a wind turbine produce?

The amount of power output from a wind turbine depends on the speed of the upstream wind, wind turbine size, and the swept area. The maximum extractable kinetic energy from a wind turbine is limited to 16/27 ≈ 59.3% of the available wind power .

Can wind power be integrated into the electric grid?

Weather variables such as wind direction, temperature, pressure and humidity, among others, influence wind power production (Sharifian et al., 2018). Hence, to integrate wind power into the electric grid requires estimates, at least, of future wind speed values (Ammar et al., 2018).

How is wind power estimated?

Through the monthly wind speed forecast, the wind power potential is estimated. Velázquez et al. (2011a) used similar method to estimate wind power costs of certain sites, but also compared the results of the ANN method with those obtained through the linear MCP method.
