提出了一种基于整数规划的非侵入式家电负载监测技术。非侵入式电器负载监测是一个问题，以确定在一个家庭中的电器的工作条件，只有通过观察总的负载电流和电压。由于总负载电流被表示为操作设备的每个电流的叠加，因此通过将操作条件表示为整数变量，监测问题可以被公式化为整数二次规划问题。由于商业软件的最新发展，这个问题可以用足够小的计算负担来解决。所提出的方法不需要重新学习，即使当一个新的设备安装在房子里。此外，所提出的公式适用于一些器具具有多种模式的情况，以及一些相同类型的器具同时操作的情况。实验结果验证了该方法的有效性。
This paper presents a new nonintrusive appliance load monitoring technique based on the integer programming. Nonintrusive appliance load monitoring is a problem to identify the operating conditions of the electric appliances in a house only by observing the overall load current and voltage. Since the overall load current is expressed as a superposition of each current of the operating appliance, the monitoring problem can be formulated as an integer quadratic programming problem by expressing the operating conditions as integer variables. This problem is solvable with sufficiently small computational burden thanks to the recent development of the commercial software. The proposed method does not require the relearning even when a new appliance is installed in the house. Furthermore, the proposed formulation is applicable to cases that some appliance has multiple modes, and cases that some same-type appliances operate simultaneously. Usefulness of the proposed technique is verified through some experimental results.
