Example Embodiment
[0031] The preferred embodiments will be described in detail below in conjunction with the accompanying drawings. It should be emphasized that the following description is only exemplary and not intended to limit the scope of the invention and its application.
[0032] figure 1 It is an overall flow chart of short-term power prediction of wind farms provided by the present invention. Wind farm short-term power prediction includes three steps: a. Ultra-short-term (0-4h) power prediction; taking the measured wind speed, power and other data provided by the wind farm SCADA (Supervisory Control And Data Acquisition, data acquisition and monitoring) system as input, through Data processing methods such as the time series method and the power prediction method based on the combination of wavelet transform and neural network, output the predicted power of 0-4h, and the time resolution is 15 minutes; b. Short-term (0-72h) power prediction; NWP ( Numerical weather forecast) data prov...
