A STATISTICAL ANALYSIS OF WIND POWER DENSITY BASED ON THE WEIBULL AND RAYLEIGH MODELS AT THE NORTHERN REGION OF NIGERIA
Publication Date : 01/08/2013
The electric generating capacity of Nigeria is expected to be boosted before year 2020 to meet up the electric power consumption and also to achieve Federal Government objective for Nigeria to be amongst developed Nations of the world, if the annual 9.8% growth in electric power consumption continues. Nigeria has to make use of its renewable energy sources, such as wind and solar, not only to meet the increasing energy demand, but also for environmental concern. This research reports wind energy potential evaluation in some selected states in Northern Nigeria using 17- year monthly wind speed data covering the period 1990 – 2006. The results shows that in some parts of Northern Nigeria (Kano, Sokoto, Plateau and Maiduguri) the power density is greater than 100 W/m2 while in Bauchi and Abuja, the power density is less than 100 W/m2. The Rayleigh model returns a higher power density in Plateau (North Central Nigeria) with value of 1892.64 W/m2 in the month of February while for Weibull model the value for power density is 1469.81 W/m2 in the same month. The lowest error percentage was obtained in Kano (North West Nigeria) with a value of -46.2% for Weibull and -26.5% for Rayleigh in the month of April.
