Abstract

According to the International Energy Agency (IEA-2013), Electricity alone does not create all the conditions for socioeconomic growth, but it is obviously essential to meet basic human needs and facilitate the development of economic activities. For the isolated areas with high wind potential and the island suffering from the electrification problems, the prospective solution is the use of renewable energies, especially wind energy. The present paper deals with a detailed statistical study on wind energy, its parameters, and variables on Socotra Island in Yemen, where that island is isolated from the main electricity grid in addition to the difficulty of providing electrical energy to this region in light of conditions in which Yemen has been living in recent times. The simulation results prove that the mean wind speed can reach a value ranging from 8.36 to 10.36 m/s, which is a large and enough speed to generate electricity using turbine farms. Based on the k and c Weibull parameters, the maximum probability at speeds 3 and 4 m/s is 0,052, while a value of 0,085 at speed 7 m/s is given by Rayleight distribution. Every result proved that Yemen has a good wind energy potential can utilize it for electrical energy production, and that strengthens the planning of economical wind turbines capacity for electricity production in the region.

Highlights

  • The energy revolution nowadays is recommended at all scales of life

  • 3.1 Weibull distribution function The first fundamental step to assess the wind energy potential is the estimation of the wind speed probability distribution function (PDF)

  • The wind power density based on the mean wind speed, density function are given by equations (11) (12) [18]: pp(vv) AA

Summary

Introduction

The energy revolution nowadays is recommended at all scales of life It became a major element of sustainable development. There has been significant research on the development and utilization of renewable energies in Yemen. Due to their abundance, they can provide complete security of energy supply through favorable exploitation. The use of renewable energy sources remained individual, indiscriminate and is not sufficient to generate electricity for a long and arranged period as solar or wind turbine stations provide. Due to its technologies development among the renewable energy technologies, the wind energy has the advantage of being the suitable source for the area like Yemen [10 - 11].
