Statistical analysis of wind resource and energy potential assessment of Sanghar site, Sindh Pakistan

Abstract

Purpose The purpose of this paper is to assess the wind resource and energy potential of the Sanghar site for minimizing the dependence on fossil fuels and improving the environment. Design/methodology/approach The Sanghar site wind shear coefficient and turbulence intensity factor are investigated for a period of a year. The two-parameter k and c Weibull distribution function is used to analyze the wind speed of the Sanghar site. The standard deviation, coefficient of variation, wind power density and energy density; and capacity factor was assessed for a period of a year. The economic assessment of energy/kWh is investigated for the selection of appropriate wind turbines. Findings The mean wind shear of the Sanghar site was found to be 0.2509. The mean wind speed was found to be 4.766, 5.534 and 6.121 at 20, 40 and 60 m above the ground level. The mean value of the k parameter was observed to be 2.433, 2.777 and 2.862 at 20, 40 and 60 m for a period of a year. The Weibull c m/s parameter was found to be 5.377, 6.245 and 6.906 m/s at 20, 40 and 60 m. The major portion of values of standard deviation was found to be in between 0.1 to 2.00 at 20, 40 and 60 m. The mean wind power density values were observed to be 88.33, 93.5 and 110.16 W/m2 at 20, 40 and 60 m; respectively, for a period of a year. The mean coefficient of variation was found to be 0.1478, 0.1205 and 0.1033 at 20, 40 and 60 m; respectively. The mean energy density was found to be 476.75, 683.08 and 866.33 kWh/m2 at 20, 40 and 60 m; respectively. The mean capacity factor for different wind turbines was ranged between 18 to 24.83 for a period of a year. The economic assessment showed that wind turbine B has the minimum cost (US$) 0.0484/kWh. Practical implications The assessment provides the solution to sustainable energy generation which reduces the consumption of fuel and the effect of fluctuating price of fuel in the world market on local consumers. Social implications Wind energy may have social implications including environmentally friendly, consistent supply of energy during the peak summer season, less unit per cost, etc. Originality/value The Sanghar site is new and assessed for the first time in this research work. The Sanghar site is suitable for installing utility wind turbines for energy generation at the lowest cost.

Power policies, challenges, and recommendations of renewable resource assessment in Pakistan

“…The wind resource and energy potential assessment of the Sujawal site was investigated to determine the potential of site at 20, 40, 60 and 80 m in (Hulio, 2020). To assess the wind resouce and energy potential of Sanghar site, the detailed study was carried out at three hieghts including 20, 40 and 60 m. The site witnessed the potential of energy generation at lowest cost (Hulio et al, 2021a). In another potential assessment of Quaidabad site has been carried out at 20, 40, 60 and 80 m neighboring to major industrial hub of Pakistan, Karachi.…”

“…The most important among these is Gharo-Ketti Bandar wind corridor fall in southern part of Pakistan was accounts for 50 GW and prioritized by the GOP. The recent studies of wind resource and economic assessment of this region has been given in following literature (Hulio, 2020;Hulio et al, 2021aHulio et al, , 2021bHulio and Jiang, 2020). The wind resource and energy economic assessment of Gharo site has been carried out at 10, 30 and 50 m. The authors concluded that the site is suitable for isntalling the utility wind turbines (Hulio, 2021).…”

“…The following publications contain information on the wind resource and economic assessment [36,37]. Gharo's wind resource and energy economics were meas ured at 10, 30, and 50 m. The authors found the site suitable for utility wind turbines [38] Karachi Port Trust's (KPT) wind resource analysis reveals that the site can produce powe [36]. Sujawal's wind resource and energy potential were assessed at 20, 40, 60, and 80 m [36].…”

“…Sujawal's wind resource and energy potential were assessed at 20, 40, 60, and 80 m [36]. At 20, 40, and 60 m, Sanghar's wind resources and energy potential were analyzed The site showcased cheap energy generation [38]. Another probable Quaid Abad site study was performed 20, 40, 60, and 80 m from Karachi, Pakistan's most prominent in…”
