Wind resource and energy potential assessment of the Sujawal site, Sindh Pakistan

Wind resource and energy potential assessment of the Sujawal site, Sindh Pakistan PurposeThe objective of this paper to assess the wind energy potential of the Sujawal site for minimizing the dependence on fossil fuels.Design/methodology/approachThe site-specific wind shear coefficient and the turbulence model were investigated.

Abstract

PurposeThe objective of this paper to assess the wind energy potential of the Sujawal site for minimizing the dependence on fossil fuels.Design/methodology/approachThe site-specific wind shear coefficient and the turbulence model were investigated. The two-parameter, k and c, Weibull distribution function was used to analyze the wind speed of the Sujawal site. The standard deviation of the site was also assessed for a period of a year. Also, the coefficient of variation was carried out to determine the difference at each height. The wind power and energy densities were assessed for a period of a year. The economic assessment of energy/kWh was investigated for selection of appropriate wind turbine.FindingsThe mean wind shear of the Sujawal site was found to be 0.274. The mean wind speed was found to be 7.458, 6.911, 6.438 and 5.347 at 80, 60, 40 and 20 m, respectively, above the ground level (AGL). The mean values of k parameter were observed to be 2.302, 2.767, 3.026 and 3.105 at 20, 40, 60 and 80 m, respectively, for a period of a year. The Weibull c m/s parameter values were found to be 8.415, 7.797, 7.265 and 6.084 m/s at 80, 60, 40 and 20 m, respectively.
