The energy crisis witnessed in the early seventies is a serious problem that had happened in the universe. Hence, induction of renewable energy into electrical power generation mix can serve as an alternative source to cater for the limited reserve of fossil fuels. Wind energy is promising and has emerged as one of the safest, cleanest and fastest growing renewable energy in the recent years. T...

The present study analyzes air quality for Carbon monoxide (CO), in Esfahan with the measurements taken in three different locations to prepare average data in the city. The average concentrations have been measured every 24 hours, every month and every season with the results showing that the highest concentration of CO occurs generally in the morning and at the beginning of night, while the l...

Wind is a dominant source of renewable energy with high sustainability potential. However, the intermittence and unstable nature wind affect efficiency reliability conversion systems. The prediction available potential also heavily flawed by its nature. Thus, evaluating trough speed prevision, crucial for adapting production to load shifting user demand rates. This work aims forecast using stat...

. introduction tropical cyclones (tcs), all over the world, are recognized as the most common and most devastating of all the natural disasters. nearly 80–90 tcs occur around the globe that about 40–50 attain intensity of 33 m/s (frank and george, 2007). approximately 7% of tcs originate in north of indian ocean and nearly 2% in arabian sea (wmo report, 2008). the prediction of tc track has bee...

Large-scale offshore wind farms (OWF) are under construction along the southeastern coast of China, an area with a high typhoon incidence. Measured data and simulation model used to improve reliability extreme speed (EWS) forecasts for OWF affected by typhoons in this paper. Firstly, 70-year historical record database is statistically analyzed fit parameters probability distribution functions, ...

A large body of work has shown that year-to-year variations in North African dust emission are inversely proportional to previous-year monsoon rainfall in the Sahel, implying that African dust emission is highly sensitive to vegetation changes in this narrow transitional zone. However, such a theory is not supported by field observations or modeling studies, as both suggest that interannual var...

As one of the fastest-growing new energy sources, wind power technology has attracted widespread attention from all over world. In order to improve quality generation, speed prediction is an indispensable task. this paper, error correction-based Variational Mode Decomposition and Broad Learning System (VMD-BLS) hybrid model proposed for prediction. First, decomposed into multiple components by ...
