针对综合能源系统负荷预测存在的多源异构数据融合与不确定性量化机制不足问题,利用卷积神经网络(CNN)提取负荷数据局部特征,通过双向长短期记忆网络(BiLSTM)捕捉双向时序依赖,采用随机森林(RF)处理高维非线性关系并借助核密度估计(KDE)量化预测不确定性,从而建立CNN-BiLSTM-RF-KDE混合模型;同时,构建电-热-气多能流耦合模型,分析不同碳价区间对调度策略的影响。算例分析显示:训练集上电、热负荷预测的决定系数分别为0.93,0.96;测试集上电、热负荷预测的决定系数分别为0.79,0.84。预测出的各设备发电、发热量与均值趋势高度吻合,表明运用该模型能够得出更接近准确值的负荷量,以此为基础数据,可以对综合能源系统进行更为可靠的分析与调度。
To address the challenges of insufficient multi-source heterogeneous data fusion and uncertainty quantification in load forecasting for integrated energy systems, a hybrid CNN-BiLSTM-RF-KDE model was proposed. The model utilized convolutional neural network(CNN) to extract local features of load data, bidirectional long short-term memory (BiLSTM) to capture bidirectional temporal dependencies, random forest(RF) to handle high-dimensiona
l nonlinear relationships, and kernel density estimation(KDE) to quantify prediction uncertainty. Additionally, an electricity-heat-gas multi-energy flow coupling model was established to analyze the influence of different carbon price intervals on scheduling strategies. Case studies demonstrated that the coefficient of determination(
R
²) for electrical and heating load forecasting reached 0.93 and 0.96 on the training set, and 0.79 and 0.84 on the test set, respectively. The predicted power generation and heat output of each device closely aligned with the mean trend, indicating that the model provided more accurate load predictions. Based on this data, more reliable analysis and scheduling of integrated energy systems could be achieved.
