Short-Term Urban Power Load Interval Forecasting Model Based on IWOA-iTransformer-QR

中文摘要英文摘要

随着可再生能源与新型负荷的接入,电力负荷预测的不确定性显著增加.为此,提出一种基于改进鲸鱼优化算法(IWOA)的iTransformer分位数回归模型(IWOA-iTransformer-QR).该模型通过IWOA自动优化超参数,结合iTransformer与分位数回归实现特征建模与不确定性的同步量化.算例结果表明,该模型在短期城市电力负荷预测中显著优于长短期记忆网络(LSTM)、门控神经网络(GRU)和Transformer,均方根差(RMSE)降幅超过70%,且能提供可靠的预测区间.研究证明该方法在提升预测精度与可信度方面具有潜力,可为电力系统调度与运行提供支持.

With the connection of renewable energy and new-type loads,the uncertainty of power load forecasting has significantly increased.In view of this,an Improved whale optimization algorithm(IWOA)-based iTransformer quantile regression model(IWOA-iTransformer-QR)is proposed.This model uses IWOA to automatically optimize hyperparameters,and combines iTransformer and quantile regression to implement feature modeling and synchronous quantification of uncertainty.The results of the calculation examples show that this model significantly outperforms the Long Short-Term Memory(LSTM)network,Gated Recurrent Unit(GRU)and Transformer in short-term urban power load forecasting,with the root mean square difference(RMSE)decreased by more than 70%,and can provide a reliable prediction range.The study has proven that the proposed method has potential in improving prediction accuracy and credibility,thus providing support for the scheduling and operation of power systems.
