Current methods to calculate capacity credit of wind power, IEA collaboration
2008-07, Ensslin, Cornel, Milligan, Michael R., Holttinen, Hannele, O'Malley, Mark, Keane, Andrew
Power systems must have enough generation to meet
demand at each moment of the day. In addition, they must also
have enough reserve to deal with unexpected contingencies. The
increase in the penetration of wind generation in recent years
has led to a number of challenges in the calculations required
to facilitate wind generation while maintaining the existing level
of security of supply. A key calculation in this process is the
capacity credit or value of wind generation. Capacity credit/value
of wind generation can be broadly defined as the amount of
firm conventional generation capacity that can be replaced with
wind generation capacity, while maintaining the existing levels
of security of supply. This topic has been the subject of much
study and debate in recent times. The aim of this paper is to
give an overview of the state of the art in this area, in particular
with regard to the work of IEA WIND Task 25 and the work
detailed in its state of the art report on the design and operation
of power systems with large amounts of wind power.
