Wind energy is one of the abundant and renewable energy sources that can be harvested using wind turbines. Many factors affect the energy-yielding ability of wind turbines. The goal of this paper is to investigate the effects of uncertain weather conditions on the power generation ability of wind turbines. Uniquely, it presented the influence of the uncertain weather conditions and uncertain aerodynamic parameters of wind turbine on wind energy harvesting. The mathematical model of these

It is found that the impact of uncertain weather conditions on annual average air density, and hence on the performance of wind turbines, is 1.33%. Whereas, the impact of variations of yearly average wind speed on the performance of wind turbines is found to be substantial. In particular, the annual uncertainty output power of wind turbines is found to be 32%. This investigation helps to find the mitigation mechanism and improve power generation efficiency from wind.
