Effects of Clusters on the Electric Power from Windfarms

It is expected that a large number of wind turbine generators (WTG´s) will be operating in the near future in certain parts of the country. And according to the current trend most of these WTG´s will be owned and operated by entities other than the utility. Consequently, a large fraction of these machines will be placed in clusters in relatively small windrich areas. Also ways and means have to be found for properly evaluating the power from wind.
