摘要:

能源分解以非侵入性的方式估计电器水平的电力消耗从一个单一的米,衡量整个房子的电力需求。近年来,随着能源数据的不断增加,有许多数据驱动的深度学习架构被应用于解决非侵入式能源分解问题。然而,大多数提出的方法试图估计开关状态或设备的功耗,这不仅需要大量的参数,而且需要在训练之前进行超参数优化,甚至对指定设备的能量数据进行预处理。本文采用神经网络来估计电器的运行状态变化,而不是估计开关状态或功耗。与以前的方法相比,我们提出的解决方案在各种设备上更可行,复杂性更低。在低采样率数据集REDD上的仿真实验表明,该方法与基于隐马尔可夫模型的方法和基于图信号处理的方法相比,具有较好的性能。

英文摘要:

Energy disaggregation in a non-intrusive way estimates appliance level electricity consumption from a single meter that measures the whole house electricity demand. Recently, with the ongoing increment of energy data, there are many data-driven deep learning architectures being applied to solve the non-intrusive energy disaggregation problem. However, most proposed methods try to estimate the on-off state or the power consumption of appliance, which need not only large amount of parameters, but also hyper-parameter optimization prior to training and even preprocessing of energy data for a specified appliance. In this paper, instead of estimating on-off state or power consumption, we adapt a neural network to estimate the operational state change of appliance. Our proposed solution is more feasible across various appliances and lower complexity comparing to previous methods. The simulated experiments in the low sample rate dataset REDD show the competitive performance of the designed method, with respect to other two benchmark methods, Hidden Markov Model-based and Graph Signal processing-based approaches.
