Embodiment Construction
[0069] The present invention will be further described in detail below with reference to the accompanying drawings.
[0070] like figure 1 As shown, a wind power cluster trajectory prediction and hierarchical control method according to the present invention includes the following steps:
[0071] Step A. Perform ultra-short-term wind power prediction based on spatial correlation and NWP data according to the topological structure of the wind power cluster and the wind farm, and obtain the wind power prediction value.
[0072] A1. Set the spatial coordinate T of each wind farm or each wind turbine in the wind power cluster i (x i ,y i ,z i ), the wind speed at the hub of each fan wind direction d i (0°~360°, with true north as 0° and 360°, clockwise), the wind speed of each wind farm is measured by the wind tower wind direction d i , the wind power P i , the horizontal distance between the two wind farms is Δl ij ;
[0073] According to the historical data time ser...
