How can I calculate the output power of wind turbine ?

Hi all, I am trying to calculate the output power of wind turbine and the power should be zero below cut in and above cut out and equal to rated from rated speed till cut out

my question is what about the part from cut in till rated speed , i used the general equation to calculate it which is

p=0.5*swept area* air density*capacity factor *v3

the problem is some values above rated power is there any thing wrong i need help

Power output is calculated as follows: power = [(air density) times (swept area of blades) times (wind speed cubed)] divided by 2. The area is in meters squared, air density is in kilograms per meters cubed and wind speed is in meters per second.

Power = 0.5 x Swept Area x Air Density x Velocity3
