Abstract: With the fast development of wind power installation in China, wind power integration capacity constrained by load regulation capability becomes the key problem in power system, and accurate wind power forecasting of high proportion wind power becomes more and more important. At present, wind power forecasting plays a key role in dealing with the challenges of balancing supply and demand in any electricity system. In the future, short-term and ultra-short-term wind power forecasting will play a greater role in standby market, spot market and auxiliary service market, which is an important support means for wind power to participate in market transactions. In this paper, research and periodic summary are illustrated on the roadmaps and applications of wind power forecasting, including the whole process of numeric weather prediction, wind power conversion model, wind power forecasting system applications and evaluation indices of forecasting performance, and the prospects in future technical route are provided.
