    Forecast Correction and Risk-Constrained Dispatch for Industrial Integrated Energy Systems

    • 摘要: 提出一种面向调度目标的工业综合能源系统预测输入修正方法。构建负荷画像驱动的预测路线,基于验证集方向性残差分位数提取前馈修正参数,并在统一滚动调度模型下评价候选调度输入方案,实现预测误差方向性与运行后果的关联。采用本文提出的预测输入修正方法,对某烟厂工业园区综合能源系统开展多类源荷预测与滚动调度算例分析。结果表明:负荷画像驱动模型选择能够提高整体预测精度,但平均绝对误差(mean absolute error,MAE)和均方根误差(root mean square error,RMSE)等对称误差指标难以充分反映需求侧低估和供给侧高估风险;风险预算选择性修正方案C4使方向性风险降低20.55%,成本和碳排放量分别增加10.74%和10.52%,在满足20%风险预算约束下具有较优综合性能;方向性残差校准可为调度输入修正提供依据,兼顾运行安全性、经济性和低碳性。

       

      Abstract: A dispatch-oriented forecast input correction method for industrial integrated energy systems is proposed. A load-profile-driven forecasting route is constructed, feedforward correction parameters are extracted from directional residual quantiles on the validation set, and candidate dispatch input schemes are evaluated under a unified rolling dispatch model, thereby linking the directionality of forecast errors with their operational consequences. A case study of a tobacco factory industrial park shows that load-profile-driven model selection can improve overall forecasting accuracy, whereas symmetric error metrics, such as mean absolute error (MAE) and root mean square error (RMSE), cannot adequately characterize the risks associated with demand-side underestimation and supply-side overestimation. The risk-budget selective correction scheme C4 reduces directional risk by 20.55%, with increases of 10.74% in operating cost and 10.52% in carbon emissions, and achieves favorable overall performance under the 20% risk-budget constraint. The results indicate that directional residual calibration can provide a basis for dispatch input correction while balancing operational safety, economic performance, and low-carbon performance.
