This article is great, with some minor editing.  Thanks.

asdf's comments are valid, but are not completely relevant to the vast majority of installed windpower MW.  There is a huge difference between connecting to a local distribution grid, as in pv, and the transmission grid, as in windparks.

the changes to the entire grid are already underway, and the smart grid concept has already taken root.  But it is essential to realize that large windparks connect at much higher voltages on the transmission system, very rarely to distribution wires.  different set of concerns.
