Non-intrusive load decomposition method, device and equipment

Abstract

The invention discloses a non-intrusive load decomposition method, device and equipment, and the method comprises the steps of obtaining a power sequence of each complex electric appliance through a load decomposition model corresponding to the complex electric appliance based on a total active power sequence of real-time operation of all electric appliances in a to-be-subjected-to-load decomposition space; and then stripping the power sequence of the complex electric appliance from the total active power sequence to obtain the total power sequence of the simple electric appliance, and finally determining the power sequence of the simple electric appliance according to a load characteristic detection model corresponding to the simple electric appliance one by one and a starting power pre-estimated value. The load decomposition model and the load feature detection model used in the application are in one-to-one correspondence with the electrical appliances, so that even if the number of the electrical appliances in the space to be subjected to load decomposition is increased, only a special model required by the newly added electrical appliances needs to be trained, and all the electrical appliances do not need to be trained again, thereby reducing time consumption in the training process, and improving the working efficiency.

Description

technical field [0001] The invention relates to the field of non-invasive load splitting, in particular to a non-invasive load splitting method, and also relates to a non-invasive load splitting device and equipment. Background technique [0002] Non-intrusive load decomposition technology can monitor users' electricity consumption behavior in real time, and has low equipment installation cost and high user acceptance. It has become an important technical means to achieve friendly interaction between users and the grid. When a family or company) conducts non-intrusive load decomposition, a load monitoring model will be established for all electrical appliances in the target space as a whole. Once new electrical appliances are added to the target space, the original load monitoring model will no longer be applicable and must be targeted at the target space At present, all electrical appliances retrain a load monitoring model. Since the training time of the load monitoring mod...

[0002] Non-intrusive load decomposition technology can monitor users' electricity consumption behavior in real time, and has low equipment installation cost and high user acceptance. It has become an important technical means to achieve friendly interaction between users and the grid. When a family or company) conducts non-intrusive load decomposition, a load monitoring model will be established for all electrical appliances in the target space as a whole. Once new electrical appliances are added to the target space, the original load monitoring model will no longer be applicable and must be targeted at the target space All current electrical appliances retrain a load monitoring model. Since the training time of the load monitoring model is proportional to the total number of corresponding electrical appliances, this training process takes a long time, consumes a lot of time, and has poor work efficiency.
