Abstract

Non-Intrusive Load Monitoring (NILM) aims to disaggregate smart meter measurement into individual appliance-level power consumption. Existing Transformer-based models in NILM often fail to capture local signal features, resulting in suboptimal decomposition performance and excessive training times. To address these challenges, we propose Mamba2NILM, a hybrid framework integrating the Squeeze and Excitation networks (SENet) and Mamba2 into a Transformer architecture. This design synergistically balances local feature extraction and global context modeling, while reducing computational complexity. Additionally, the embedded SE module emphasizes indirect enhancement of periodic features and dynamic screening of multi-scale features. Experimental evaluations, including quantitative metrics and visual analysis, confirm that Mamba2NILM achieves superior efficiency and effectiveness, outperforming state-of-the-art baselines.

MAMBA2NILM：一种非侵入式负载监测方法，结合了SENet注意机制和Mamba2

非侵入式负载监测（NILM）旨在将智能电表测量分解为单个电器级功耗。现有的基于变压器的NILM模型往往不能捕获局部信号特征，导致分解性能不理想和训练时间过长。为了应对这些挑战，我们提出了Mamba2NILM，这是一个将挤压和激励网络（SENet）和Mamba2集成到Transformer架构中的混合框架。这种设计协同平衡了局部特征提取和全局上下文建模，同时降低了计算复杂性。此外，嵌入式SE模块强调周期性特征的间接增强和多尺度特征的动态筛选。实验评估，包括定量指标和视觉分析，证实Mamba2NILM具有卓越的效率和有效性，优于最先进的基线。

期刊介绍： Electric Power Systems Research is an international medium for the publication of original papers concerned with the generation, transmission, distribution and utilization of electrical energy. The journal aims at presenting important results of work in this field, whether in the form of applied research, development of new procedures or components, orginal application of existing knowledge or new designapproaches. The scope of Electric Power Systems Research is broad, encompassing all aspects of electric power systems. The following list of topics is not intended to be exhaustive, but rather to indicate topics that fall within the journal purview. • Generation techniques ranging from advances in conventional electromechanical methods, through nuclear power generation, to renewable energy generation. • Transmission, spanning the broad area from UHV (ac and dc) to network operation and protection, line routing and design. • Substation work: equipment design, protection and control systems. • Distribution techniques, equipment development, and smart grids. • The utilization area from energy efficiency to distributed load levelling techniques. • Systems studies including control techniques, planning, optimization methods, stability, security assessment and insulation coordination.
