Wind power generation and appropriate feed-in-tariff under

To expand energy access, it is necessary to enhance energy efficiency and to invest in renewable energy (Anon, 2021c). the uncertainty in the production of wind power plants is expressed in terms of the probability of exceedance values P50, P75 and P90 (Yue et al., 2019). In this terminology, P50 means that there is a probability of 50%

Terminology explained: P10, P50 and P90

It is a common misunderstanding that the P50 is a synonym of mean. This will be true is the probability distribution function for the observations were symmetrical. In this case, the mode, mean and P50 would all be the same. In Maros and Taro, we call the P50 by an alternative name to avoid confusion: Median. For distributions where the values
