WebJan 23, 2024 · The value of a gradient might be potentially positive or negative. The x-axis gradient is 0 because the slope of a horizontal line is zero. The y-axis gradient is indeterminate because the slope of a vertical line is undefined. The slope of a curve at every point on the curve is the same as a slope of its tangent at a certain point. WebThis work presents a computational method for the simulation of wind speeds and for the calculation of the statistical distributions of wind farm (WF) power curves, where the wake effects and terrain features are taken into consideration.
