Aimed on solving the potential difficulty of power grid operation and dispatching in wind power developed provinces of china, this paper presents a modeling methodology of day-ahead optimal dispatching to coordinate wind power. By considering the short-term and medium-and-long-term wind power prediction, the day-ahead optimal dispatching decision process combined with the concept of energy saving generation dispatching strategy has been studied. Also the unit commitment model and 96-points generation planning model suitable for practical grid application have been created in this paper. Finally, the recommended model were analyzed with actual grid operating data, the effectiveness and rationality of these model have been demonstrated.
