为了加快节能减排的建设和加强需求侧的用电管理,非侵入式负荷监测凭借其易实施性和可靠性等特点已成为研究热点,但目前的研究存在着低频数据负荷识别精度低、高频数据特征提取复杂及网络泛化性能差等问题。因此,提出基于ResNeXt网络和迁移学习的非侵入式负荷监测,采用一维时间序列总功率通过格拉姆角场(GAF)算法转换为带有时间特性的二维图像作为输入,放入迁移学习下ResNeXt网络进行负荷识别。该方法采用现有电表采集的低频数据作为输入,减少数据输入维度并加入了时间特性,再将输入图像进行标准化处理后通过堆叠深层次的残差神经网络来学习负荷深层次信息,利用迁移学习将在ImageNet-1K数据集下已训练好的网络模型参数传入新的目标域,加快网络的收敛速度,提高负荷分类的识别准确率和网络的泛化性。最后,利用公开数据集AMPds和UK-DALE模拟不同用电场景验证了所提方法的高效性和泛化性。
In order to speed up the construction of energy saving and emission reduction
and strengthen the electricity consumption management on the demand side
the non-intrusive load monitoring has become a research hotspot because of its easy implementation and reliability. However
the current research has some problems
such as low identification accuracy of low-frequency data load
complex extraction of high-frequency data features and poor network generalization performance. Therefore
this paper proposes a non-intrusive load monitoring based on ResNeXt network and transfer learning. The one-dimensional time-series total power is converted into two-dimensional image with time characteristics as input through Gram angle field (GAF) algorithm
and the image is put into ResNeXt network under transfer learning for load identification. This method uses the low-frequency data that can be collected by the existing meter as the input
reduces the data input dimension and adds time characteristics. And then
after the images are standardized
the deep load information is learned by stacking the residual neural network with deep-layers
and the trained network model parameters under ImageNet-1K dataset are transferred to the new target domain by transfer learning
so as to accelerate the convergence speed of the network
improve the accuracy of load classification and the generalization of the network. Finally
this method is verified by using the open data sets AMPds and UK-DALE to simulate different power consumption scenarios
which verifies the efficiency and generalization of the proposed method.
