Embodiment Construction
[0043] Improving the prediction accuracy of wind power in wind farms can effectively reduce the huge impact on the stable operation of the grid when intermittent power sources with high permeability are connected to the grid, and at the same time can improve the system's ability to absorb new energy grid-connected. One of the difficulties in wind power forecasting modeling is to infer the hidden laws from limited samples and to identify unknown systems from experimental data. The inherent randomness, intermittentness and volatility of wind power increase the difficulty of short-term wind power forecasting.
[0044] The invention relates to a multi-scale resolution decomposition of wind speed using a two-dimensional wavelet to reduce the effects of instantaneity, randomness and uncertainty in wind speed, and then use a multi-model AdaBoost deep network to improve neural network integration and ease Falling into the defects of local minimums, enhancing the adaptability to different...
