Gregor Giebel: Wind
Power has a Capacity Credit - A Catalogue of 50+ Supporting Studies.

While many studies on wind energy in Europe and the capacity credit of wind energy have been made, none so far has looked at a common European grid. At the end of this survey, a short summary of the lessons learned will be given. Footnote numbering is a problem when taking pieces over from Word to Frontpage - I didn't get it cleared up properly, sorry for the confusion.
Allow me to introduce the terminology first:
Installed
Capacity refers to the nameplate
capacity of the turbine multiplied by the number of turbines. Penetration
is the percentage of installed wind energy capacity in the grid. Occasionally,
penetration is also used to denote the percentage of load served by wind energy.
Note that in the following the additionally installed capacity is used, scaled
as a percentage of the existing grid, as opposed to a proper penetration figure;
the reason is an easier batch routine set-up. When not discussing values, the
terms penetration and additionally installed wind capacity might be used
interchangeably.
