New method to model the wind speed distribution: method of decile

Energy is a primary need for individuals and societies; the new era has revolutionized everything, from cell phones to daily used equipment in houses; all need electrical energy. Advanced countries have already managed energy demand according to their need. Renewable energy is better than conventional energy sources such as gas, coal, and nuclear fuel. Researchers have continuously worked on renewable energy to make it as helpful as possible. Mathematical modeling and new methods of harnessing energy are the leading fields researchers are working in. Wind energy is ubiquitous; however, it depends on a cut-off speed. In numerous places worldwide, the wind speed surpasses the cut-off speed. Such locations are good candidates for generating electricity from wind energy. Proper modeling of wind energy enables one to know available wind potential. An effort has been made to model wind speed; a new method known as the method of decile has been developed. The method works using the first and last decile of the wind distribution. The Weibull parameters, average wind speed, and errors have been calculated and compared to five other methods. Akaike information criterion (AIC) was used to see the suitability of the new method. The AIC values for the new method were calculated for 12 months of wind speed data in 2016; the minimum values occurred for the novel method. It shows that the new method is the best among the other five methods. The annual output energy is estimated using E-5 (by Ryse Energy company) horizontal axis wind turbine and evaluated as 6900 kWh at Hyderabad, the highest among the three sites.
