Wind Power Curve

Problem

Evaluate a wind turbine power curve. Below cut_in or above cut_out the power is 0.0; at or above rated_speed it is rated_power; in between it follows the cube of the normalized wind speed: rated_power * ((speed - cut_in) / (rated_speed - cut_in))^3.

Return the power for the given speed.

Hint

The cubic region captures the physics of available wind power.
