Embodiment Construction
[0023] Finally, before introducing the above-mentioned method for evaluating short-term power prediction accuracy of wind farms, it is necessary to explain the short-term power modeling and prediction methods of wind farms on which the evaluation method is based to help understand the implementation principle of the method of the present invention. Such as figure 1 As shown, the short-term power modeling and prediction methods for wind farms mentioned here mainly include the following steps:
[0024] Step 101: Prepare data before modeling for the short-term power prediction model of the wind farm to be built, including:
[0025] a) Collect data
[0026] In this step, the data of the wind farm for the past year is sampled, where the sampling period is 15 minutes, and the data includes:
[0027] Historical measured data, mainly including wind speed, power, ambient temperature, average wind speed of wind farm, power at the gate, wind speed, wind direction and temperature of wind tower;
