Two methods are proposed to assess the impact of multiple wind farms on a large electrical power system. The methods are based on the Monte Carlo simulation of the wind speed occurring in each wind farm, taking into account measurements of mean values and correlations. The first method is bas...
Finally, since many wind farms are sitting on rough or sloped terrains, it is also essential to understand and quantify the humidity changes associated with these conditions, either by observations or simulations. Author Contributions Empirical observations, K.A.A.; Numerical simulations, A.S.; ...
A major concern of wind farms relates to negative environmental impacts associated with noise, visual disturbance, and impacts on wildlife. Two kinds of noise associated with turbines are mechanical noise, which is produced by its equipment such as its gearbox, and aerodynamic noise, which is produ...
Fifty wind farms have opened in Illinois since 2003 and more are in the works, but not everyone is on board. The state ranks sixth nationwide with 2,778...
