摘要:

本文提出了一种改进的顺序到点(S2P)算法分解的热,通风,空调(HVAC)负荷从总建筑用电量。原始的S2P模型是基于卷积神经网络(CNN)的,其使用负载简档作为输入。我们提出三项修改。首先,输入卷积层从1D变为2D,使得归一化温度曲线也用作S2P模型的输入。其次,添加了一个退出层以提高适应性和泛化能力,以便在一个区域中训练的模型可以在没有标记HVAC数据的情况下转移到其他地理区域。第三,针对具有少量标记的HVAC数据的区域提出微调过程,使得预训练的S2P模型可以被微调以实现更高的分解准确度(即,更好地适应其他领域。该模型首先使用在德克萨斯州奥斯汀收集的智能电表和分项计量HVAC数据进行训练和测试。然后,在另外两个地区对训练好的模型进行测试:科罗拉多州的博尔德和加利福尼亚州的圣地亚哥。仿真结果表明,改进的S2P算法在准确性、适应性和可移植性方面优于原始S2P模型和基于支持向量机的方法。

英文摘要:

This paper presents a modified sequence-to-point (S2P) algorithm for disaggregating the heat, ventilation, and air conditioning (HVAC) load from the total building electricity consumption. The original S2P model is convolutional neural network (CNN) based, which uses load profiles as inputs. We propose three modifications. First, the input convolution layer is changed from 1D to 2D so that normalized temperature profiles are also used as inputs to the S2P model. Second, a drop-out layer is added to improve adaptability and generalizability so that the model trained in one area can be transferred to other geographical areas without labelled HVAC data. Third, a fine-tuning process is proposed for areas with a small amount of labelled HVAC data so that the pre-trained S2P model can be fine-tuned to achieve higher disaggregation accuracy (i.e., better transferability) in other areas. The model is first trained and tested using smart meter and sub-metered HVAC data collected in Austin, Texas. Then, the trained model is tested on two other areas: Boulder, Colorado and San Diego, California. Simulation results show that the proposed modified S2P algorithm outperforms the original S2P model and the support-vector machine based approach in accuracy, adaptability, and transferability.
