The formula for wind power is: pv3/2, air density times the cube of wind speed and divided by 2. (But this is not actually the case, because the wind turbine itself cannot capture all the wind energy. Each wind turbine manufacturer will have a wind energy curve. Thanks to this wind energy curve, we can find the power supplied corresponding to the determined wind speed.
The formula for wind speed changing with height:
Wind shear index a=[lg(v2/v1)]/[lg(z2/z1)]
V2 is the height at Z2 Wind speed
V1 is the wind speed at height Z1
The calculation is like this
First of all, you need to know the four data of V2, V1, Z2 and Z1, then find a, then use a=[lg(V1/V3)]/[lg(Z1/Z3)] to find wind speed V3 at height Z3. Of course, this formula does not calculate the actual V3 but only the theoretical value.
