This seminar is to discuss wind power forecasting and its use in power system operations. The presentation is structured into two parts. The first part concentrates on surveying existing wind power forecasting methodologies and identifying strengths and limitations of different approaches. The second part of the presentation addresses how power system operators can incorporate advanced wind forecasting technologies into their operations. Improved unit commitment and dispatch algorithms to address variability and uncertainty of wind power will be discussed. A numerical example will be shown to illustrate one feasible unit commitment and dispatch solution to integrate variable wind energy into power system operations.
