Embodiment Construction
[0017] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.
[0018] Such as figure 1 Shown, the present invention provides a kind of wind farm short-term power prediction method, detailed following steps:
[0019] Step (1), initialize and select the actual power generation P that is Pdays=28 days away from the current day 实 and short-term power prediction data P 短期 , with a time resolution of 15 minutes per point.
[0020] Step (2), for all the actual power generation data of the wind farm in the corresponding time period after the first round of screening, solve to obtain the average value of the actual power generation P 实平均 , and at the same time solve the average value of the short-term power forecast data of the wind farm in this period, and get P 短期平均 .
[0021] Step (3), calculate the correlation coefficient r1 between the actual generated power and the short-term power forecast dat...
