State-of-the-art of design and operation of power systems with large amounts of wind power: Summary of IEA Wind collaboration. In: EWEC 2007 - European Wind Energy Conference & Exhibition, Milan, Italy, 7-10 May, 2007, 11 p.http://hdl.handle.net/10400.9/1949An international forum for exchange of knowledge of power system impacts of wind power has been formed under the IEA Implementing Agreement on Wind Energy. The task “Design and Operation of Power Systems with Large Amounts of Wind Power” is analysing existing case studies from different power systems.There are a multitude of studies made and ongoing related to cost of wind integration. However, the results are not easy to compare. This paper summarises the results from 15 case studies.engWind powerWind energyEA Wind collaborationState-of-the-art of design and operation of power systems with large amounts of wind power: Summary of IEA Wind collaborationconference object
