基于因子分析和神经网络分位数回归的月度风电功率曲线概率预测
Month-ahead Wind Power Curve Probabilistic Prediction Based on Factor Analysis and Quantile Regression Neural Network
摘要
Abstract
Concerning the existing problems such as large number of highly correlated variables,few available weather information and high uncertainty in month-ahead wind power curve prediction,a new month-ahead wind power curve probabilistic prediction method based on factor analysis and quantile regression neural network (QRNN) was proposed.By means of the factor analysis method to reduce the dimensionality of intraday hourly wind power time series vector,the independent common factors were extracted and used as the predictor variables to separately build QRNN probabilistic forecasting models with the daily weather features as inputs.Based on these probabilistic forecasting models,the probability density functions of wind power common factors of next 30 days were predicted by inputting the daily weather features from medium-range weather forecasts.By simulating common factors and specific factors follow the predicted distributions to recover wind power forecast curves day by day,statistical scenarios of wind power production in next month were generated finally.The accuracy,adaptability and high efficiency of the proposed method have been verified by the forecasting results of two actual wind farms,which can provide a new feasible solution for the probabilistic medium-and long-term wind power forecasting.关键词
