IEA Wind Annex 25 - phase 4

The common international challenge is to adapt the existing power systems to enable a substantial increase of wind and other variable generation shares, namely PV, in a time frame considerably shorter that lifetime of the assets, meaning that this has to be done in most utility systems with existing infrastructure, and at economically feasible cost. Task 25 supports this goal by analyzing and further developing the methodology to assess the impact of wind power on power systems and by producing information on the range of impacts and best practice to assess the impacts. Expected results are: Enhanced results are: Enhanced international collaboration and coordination in the field of wind and PV integration; Set of case studies on wind and other variable generation integration, especially cases combining wind and PV, implications on market design and operation and evolved metrologies including assessment of cost and value of wind integration, uncertainty assessment and additional operational methods incorporated into planning models; Database for large scale wind power production time; collaborative journal articles; Workshops targeted for TSO audience; Updated Recommended Practices report; Updated summery describing the range of wind power impacts and costs for different power systems. DTU will contribute to the annex through participation in the meetings and sharing of the research. Research results are foreseen to be in the areas: Tools and methods for representing wind power variability and uncertainty in power systems reliability; Wind power plants control; Ancillary services from wind power plants;  Inclusion of wind power uncertainties in power system reliability assessment.
