The wind power curve indicates how much power a wind turbine should produce at any given wind speed. The maximum value from the wind power curve may be used in marketing wind turbines and for comparisons between competing models, so the values are sometimes higher than the actual output.

What makes global winds curve?
The global winds appear to curve to the right in the northern hemisphere of the Earth, and it appears to curve to the left in the southern hemisphere of the Earth. The apparent deflection of the direction of the global winds caused by the Coriolis Effect is dependent on the speed of the Earth’s rotation.
What direction do winds curve in each hemisphere?
Wind or water that travels toward the poles from the equator is deflected to the east, while wind or water that travels toward the equator from the poles gets bent to the west. The Coriolis effect bends the direction of surface currents to the right in the Northern Hemisphere and left in the Southern Hemisphere.

What is the power curve of a wind turbine?
The power curve of a wind turbine. The power output of a wind turbine varies with wind speed and every wind turbine has a characteristic power performance curve. With such a curve it is possible to predict the energy production of a wind turbine without considering the technical details of its various components.
How to find power curves?
Power curves are found by field measurements, where an anemometeris placed on a mast reasonably close to the wind turbine, but not on the turbine itself or too close to it, since the turbine rotor may create turbulenceand make wind speed measurement unreliable. If the wind speed is not fluctuating too rapidly, then one may use the wind speed measurements from the anemometer and read the electrical power output from the wind turbine and plot the two values together in a graph like the one here.
Does a power curve tell how much power a wind turbine will produce?
A power curve does not tell how much power a wind turbine will produce at a certain average wind speed. Remember, that the energy content of the wind varies very strongly with the wind speed, as sawn in page Energy of wind. So, it matters a lot how that average came about, i.e. if winds vary a lot or if the wind blows at a relatively constant ...
Is wind speed a 3% error?
If one has a 3% error in wind speed measurement, then the energy in the wind may be 9% higher or lower, since the energy content varie s with the third power of the wind speed. Consequently, there may be errors up to plus or minus 10% even in certified power curves.
Can you place an anemometer in front of a wind turbine?
It is not a workable solution just to place an anemometer in front of the turbine, since the turbine will also cast a "wind shadow" and brake the wind in front of itself. In practice, therefore, one has to take an average of the different measurements for each wind speed and plot the graph through these averages.
What are the aspects of wind?
Winds have various aspects: velocity ( wind speed ); the density of the gas involved; energy content or wind energy. The wind is also a critical means of transportation for seeds, insects, and birds, which can travel on wind currents for thousands of miles.
What is wind movement?
Wind is the natural movement of air or other gases relative to a planet's surface. Wind occurs on a range of scales, from thunderstorm flows lasting tens of minutes, to local breezes generated by heating of land surfaces and lasting a few hours, to global winds resulting from the difference in absorption of solar energy between ...
How does wind affect the atmosphere?
The wind is caused by differences in atmospheric pressure which is mainly caused by temperature difference. When a difference in atmospheric pressure exists, air moves from the higher to the lower pressure area, resulting in winds of various speeds. On a rotating planet, air will also be deflected by the Coriolis effect, except exactly on the equator. Globally, the two major driving factors of large-scale wind patterns (the atmospheric circulation) are the differential heating between the equator and the poles (difference in absorption of solar energy leading to buoyancy forces) and the rotation of the planet. Outside the tropics and aloft from frictional effects of the surface, the large-scale winds tend to approach geostrophic balance. Near the Earth's surface, friction causes the wind to be slower than it would be otherwise. Surface friction also causes winds to blow more inward into low-pressure areas.
Why do large scale winds blow inward?
Near the Earth's surface, friction causes the wind to be slower than it would be otherwise. Surface friction also causes winds to blow more inward into low-pressure areas.
What is the term for a wind that is strong and fast?
In meteorology, winds are often referred to according to their strength, and the direction from which the wind is blowing. Short bursts of high speed wind are termed gusts. Strong winds of intermediate duration (around one minute) are termed squalls.
How does wind affect animals?
When combined with cold temperatures, the wind has a negative impact on livestock. Wind affects animals' food stores, as well as their hunting and defensive strategies.
How did wind affect human civilization?
In human civilization, the concept of wind has been explored in mythology, influenced the events of history, expanded the range of transport and warfare, and provided a power source for mechanical work, electricity, and recreation. Wind powers the voyages of sailing ships across Earth's oceans.
What is the duck curve?
Put simply, the duck curve is the graphic representation of higher levels of wind and solar on the grid during the day resulting in a high peak load in mid to late evening. The difference in the Duck Curve and a regular load chart is that the duck curve shows two high points of demand and one very low point of demand, ...
How to solve the duck curve?
This strategy involves connecting multiple energy grids together to make a large energy grid. In theory, this would broaden and disperse the load and availability of solar and wind across a larger area, which in turn would flatten the duck curve.
How does the duck curve affect electricity?
Well the duck curve kinda throws a wrench in that. In order to meet the baseline requirement, or “baseload”, utilities run BIG power plants that run on either nuclear or coal , which run around the clock. The problem with coal and nuclear power plants is that they’re expensive to completely startup and shutdown, and are more effective in ramping up or down. Then there’s the “peak load,” which is satisfied by peaker plants that usually run on natural gas, and more frequently renewables.
What are the problems with the duck curve?
So problems with the duck curve lie in those sudden and steep changes in demand. Grid operators and regulators struggle to maintain stability and efficiency by turning power plants on and off, causing instability in the power supply, large expense to taxpayers, and pollution to the environment.
Is the duck curve getting worse?
Since renewable energy has become more common over the years, the duck curve is appearing more often and is getting worse. Let’s look at an example of what the duck curve looks like:
How does wind energy work?
Wind power harvests the primary energy flow of the atmosphere generated from the uneven heating of the Earth’s surface by the Sun. Therefore, wind power is an indirect way to harness solar energy. Wind power is converted to electrical energy by wind turbines.
What are the factors that influence wind power?
Several different factors influence the potential wind resource in an area. The three main factors that influence power output are: wind speed, air density, and blade radius. Wind turbines need to be in areas with a lot of wind on a regular basis, which is more important than having occasional high winds.
Why are wind turbines spaced out?
However, larger blades require more space and higher wind speeds to operate. As a general rule, turbines are spaced out at four times the rotor diameter. This distance is necessary to avoid interference between turbines, which decreases the power output. The relative spacing between wind turbines is visible in Figure 1.
How does wind speed affect electricity?
Wind speed largely determines the amount of electricity generated by a turbine. Higher wind speeds generate more power because stronger winds allow the blades to rotate faster. Faster rotation translates to more mechanical power and more electrical power from the generator. The relationship between wind speed and power for a typical wind turbine is shown in Figure 2.
What is cut out speed?
The cut-out speed is the point at which the turbine must be shut down to avoid damage to the equipment. The cut-in and cut-out speeds are related to the turbine design and size and are decided on prior to construction.
