针对风光功率预测中频域特征挖掘不足及动态特征捕捉难题
提出了一种融合频-时域特征解析与多尺度滑动窗口特征融合的卷积-双向长短期记忆网络(CNN-BiLSTM)预测算法。首先
数据经孤立森林算法去噪后
采用皮尔逊相关系数与梯度提升回归(GBRT)的加权集成特征评估方法筛选出高相关输入特征;随后
经多尺度滑动窗口提取高相关特征时序统计量以捕获数据动态变化趋势;最后
构建基于快速傅里叶变换(FFT)频域解析与自注意力(SA)特征聚焦的CNN-BiLSTM算法
通过FFT实现频域特征提取
同时利用SA机制动态分配时序特征权重
进而实现频-时域协同表征学习
提升功率预测精度。北方某风电场与光伏电站的算例结果表明:所提算法具备较高的预测精度
在风功率预测中
平均绝对误差(MAE)和均方根误差(RMSE)分别平均降低了35.43%和31.47%
决定系数(R2)平均提高了8.04%;在光功率预测中
MAE和RMSE分别平均降低31.48%和19.39%
R2平均提高了2.19%。
To address insufficient frequency-domain feature extraction and dynamic feature capture challenges in renewable power forecasting
a convolutional neural network-bidirectional long short-term memory network (CNN-BiLSTM) algorithm integrating frequency-time domain analysis with multi-scale sliding window feature fusion was proposed. The methodology involved three phases: 1) raw data was denoised using an isolation forest algorithm
and high-relevance input features were selected through a weighted ensemble evaluation combining Pearson correlation coefficients and gradient boosting regression trees (GBRT); 2) temporal statistics were extracted via multi-scale sliding windows to capture dynamic evolution patterns; 3)the CNN-BiLSTM was augmented with fast Fourier transform (FFT)-based frequency-domain feature extraction and self-attention (SA) mechanisms for adaptive temporal weight allocation
enabling synergistic frequency-time representation learning and improved power prediction accuracy. Case studies at wind and solar farms in northern China demonstrate significant accuracy improvements. For wind power
the proposed model achieves average reductions of 35.43% and 31.47% in mean absolute error (MAE) and root mean square error (RMSE)
respectively
and an increase of 8.04% in coefficient of determination (R2). For solar power
average reductions in MAE and RMSE are 31.48% and 19.39%
respectively
and R2 improves by 2.19%.
