Abstract
Due to stochastic nature of wind distribution, wind power output comes with unscheduled changes called ramp events. In this paper, a semi-analytical approach is considered to analyze the distribution of ramp events. A simple empirical equation is derived based on the probability of wind ramp events considering the stochastic nature of wind power distribution for the Indian state of Karnataka. The proposed functional relationship shows a satisfactory approximation of the actual distribution of ramp events and helps to estimate the statistical behaviour of wind output in terms of frequency of ramp events for pre-defined threshold power outputs.
