英文摘要： Random fluctuations of wind power bring serious challenges for stable and security operation of the large scale wind power system. Identification and prediction of mutation wind power is a universal and critical difficulty. This subject focus on the application of support vector regression model and the mutation identification theory to prediction of mutation wind power, the research contents are as follows: (1) Study on the theory and method of mutation identification, propose novel methods applied to identification of mutation wind power; (2) Study on the the theory of support vector regression model, propose novel methods which are applied to build specific kernel function and selection parameters for prediction of mutation wind power, and establish an efficient and robust model to prediction of mutation wind power; (3) Predict the fluctuation range of mutation wind power, give quantitative assessment of the risk of fluctuations on the safety of wind power grid, and provide guidance for grid scheduling and control decisions. This subject is a cross-over study on theory and methods of prediction, data mining, and security warning management of power grid, the completion of this subject has important theoretical and practical significance not only on enriching the theory of mutation identification and prediction, but also on ensuring the stable operation of the power grid.
