A Parametric Approach to Compare the Wind Potential of Sanghar and Gwadar Wind Sites

Abstract

Wind is one of the world’s most rapidly expanding and environmentally friendly renewable energy sources (RES). The aim of this study is to analyze the wind potential availability in Sanghar and Gwadar cities through the wind characteristics’ analysis. To analyze the wind potential at the both sites, one-year average wind speed data (including annual, monthly, day-night, and seasonal variations) for 2020 were used. A Weibull distribution parametric approach with five different technique was applied. Along with an analysis of the wind potential, an economic assessment was also out to estimate the installation cost, turbine-cost, capacity factor of ten different wind turbines with different rated power were used at the selected sites. The results show that at the Sanghar site, the maximum power of 1612.82 kW was generated by Vestas V126/3300 whereas the minimum power 383.44 kW was generated by Nordex n60/1300. At the Gwadar site, Vestas V126/3300 generated the maximum power of 745.10 kW and least power of 157.98 kW was generated by Nordex n60/1300. With respect to an economic assessment, Vestas V126/3300 and Suzlon S66/1250 had the highest and lowest installation cost of turbines respectively at both sites. At the Sanghar site, the lowest value i.e., 0.0422 kWh/ <inline-formula xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink"> <tex-math notation="LaTeX">$\$ $ </tex-math></inline-formula> , 0.0893 kWh/ <inline-formula xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink"> <tex-math notation="LaTeX">$\$ $ </tex-math></inline-formula> and the highest values 0.081 kWh/ <inline-formula xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink"> <tex-math notation="LaTeX">$\$ $ </tex-math></inline-formula> , 0.2028 kWh/ <inline-formula xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink"> <tex-math notation="LaTeX">$\$ $ </tex-math></inline-formula> were shown by Goldwind GW121/2500 and Nordex n80/2500 at the Gwadar and Sanghar sites respectively.
