6 FAQs about [Minimum wind speed for large-scale wind power generation]

Can wind power limits be estimated without simulating atmospheric dynamics?

Large numbers of wind turbines are likely to reduce wind speeds, which lowers estimates of electricity generation from what would be presumed from unaffected conditions. Here, we test how well wind power limits that account for this effect can be estimated without explicitly simulating atmospheric dynamics.

What are large-scale Limits to wind power generation?

We evaluated large-scale limits to wind power generation in a hypothetical scenario of a large wind farm in Kansas using two distinct methods. We first used the WRF regional atmospheric model in which the wind farm interacts with the atmospheric flow to derive the maximum wind power generation rate of about 1.1 W e ⋅m −2.

What is the maximum wind power generation rate?

The VKE method predicts that the maximum generation rate equals 26% of the instantaneous downward transport of kinetic energy through hub height. This method only required the information of wind speeds and friction velocity of the control climate to provide an estimate of a maximum wind power generation rate.

How do wind turbines affect wind power generation?

Our results show that the reduction of wind speeds and limited downward fluxes determine the limits in large-scale wind power generation to less than 1 W⋅m −2. Wind turbines remove kinetic energy from the atmospheric flow, which reduces wind speeds and limits generation rates of large wind farms.

Why is large-scale wind power generation limited to 1 W E M 2?

We conclude that large-scale wind power generation is thus limited to a maximum of about 1 W e ⋅m −2 because of this inevitable reduction of wind speeds and the comparatively low vertical kinetic energy fluxes in the atmosphere.

Why do wind farms have a maximum generation rate?

This maximum rate results from a trade-off by which a greater installed capacity resulted in a greater reduction of wind speeds within the wind farm. This reduction in wind speeds reflects the strong interaction of the wind farm with the atmospheric flow, with speeds reduced by 42% at the maximum generation rate.
