This report summarises recent findings on wind integration from the 15 countries participating in the International Energy Agency (IEA) Wind collaboration research Task 25 from 2012-2014. Both real experience and studies are reported. The national case studies address several impacts of wind power on electric power systems. In this report, they are grouped under long-term planning issues and short-term operational impacts. Long-term planning issues include grid planning and capacity adequacy. Short-term operational impacts include reliability, stability, reserves, and maximising the value of wind in operational timescales (balancing related issues). The first section presents the variability and uncertainty of power system-wide wind power, and the last section presents recent wind integration studies for higher shares of wind power. Appendix provides a summary of ongoing research in the national projects contributing to Task 25 from 2015-2017.
