A Model Combining Convolutional Neural Network and LightGBM Algorithm for Ultra-Short-Term Wind Power Forecasting

Abstract: The volatility and uncertainty of wind power often affect the quality of electric energy, the security of the power grid, the stability of the power system, and the fluctuation of the power market. In this case, the research on wind power forecasting is of great significance for ensuring the better development of wind power grids and the higher quality of electric energy. Therefore, a lot of new forecasting methods have been put forward. In this paper, a new forecasting model based on a convolution neural netw… Show more

“…LightGBM has been demonstrated to be up to 20 times faster to train on the same data, 8 compared to the XGBoost 9 implementation of GB. The algorithm has been implemented successfully on issuing peer-to-peer loan in FinTech industry 10 and on forecasting wind power production in smart grid industry 11 .…”

“…If the data are too short, it cannot provide enough information to accurately predict the next photovoltaic power generation. If the data are too long, it contains too much irrelevant information affecting the judgment of the model [36]. To make the best of the prediction effect of the proposed model, we compared the mean square error (MSE) and mean absolute error (MAE) in four seasons corresponding to time-order data with different lengths.…”

“…Control parameters such as the minimum data amount of a single leaf of 15, and (GOSS) large and small gradient retention ratios of 0.2 and 0.1 are input and output parameters. The maximum number of features in a single cabinet is 255, and the minimum amount of data is 5, etc., to achieve the normal classification of power consumption feature data and power theft [32].…”
