Embodiment Construction
[0081] 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.
[0082] Aiming at the defects of existing wind farm power prediction methods, the present invention proposes a high-precision wind farm power interval prediction method based on a correlation vector machine. According to the characteristics of numerical weather prediction (NWP) error distribution, the method screens training samples, uses particle swarm optimization (PSO) to optimize the width of kernel function and iterative initial value, and comprehensively utilizes the correlation vector machine (RVM) Advantages, the establishment of a wind farm power interval correlation vector machine prediction model with high prediction accuracy, strong generalization ability, and uncertainty analysis. This method also has the ...
