Performance assessment of an unconventional lift-drag driven air-activated vertical-axis wind turbine in Northeast India: assessing a hybrid vertical axis wind turbine
摘要
The rapid growth of civilization has led to an increasing demand for electricity, causing the excessive use of fossil fuels in thermal power plants. The combustion of these fuels releases a large amount of greenhouse gases that adversely deface the environment. Renewable energy sources can potentially drive sustainable growth in modern society. Northeast India has significant solar, wind, and hydro potential. Solar and hydro have been partially explored, but wind energy remains untapped due to limited research. The average wind power densities at 150, and 200 m altitudes in Meghalaya, Manipur, Tripura, and Sikkim are 363.75 and 430.75 W/m2, respectively. In this regard, a study is conducted to assess the performance of a lift-drag driven air-activated vertical-axis wind turbine in harnessing the wind potential of northeast India. The turbine can generate 129.11W at a wind velocity of 7 m/s. When an intended turbine is installed at 150 m and 200 m, the annual yield from the study area is 5339.79, and 6411.86 kWh. Deploying 100 turbines at 150 m can conserve 140.59 tonne of fossil fuel, 220,589.889 kg of GHG, and Rs. 92.84 lakh. The average exergy and anergy due to the commissioning of these turbines at 100 m in each of the northeastern states are 61.45, and 38.55%, respectively. The levelized cost of energy due to the induction of turbines in the windy states in the regime is Rs. 3/kWh.
