In the design and calculation of stormwater drainage systems, the design rainfall intensity plays a crucial role and is widely used in runoff calculations. Due to the influence of local climatic factors, the selection of probability distributions for rainfall frequency analysis and the methods used to determine parameters for empirical equations result in a variety of equations compared to traditional Rainfall Intensity-Duration-Frequency curves.

This paper introduces a practical and simple power control method for wind energy conversion systems based on a doubly-fed induction generator. Due to the limitations of traditional proportional-integral controllers when the parameters of the doubly-fed induction generator and wind speed vary, fuzzy control theory is applied to overcome these challenges.
