Multiple electric appliance type-supportable high-precision NILM (Non-intrusive Load Monitoring) realization method

Abstract

The invention discloses a multiple electric appliance type-supportable high-precision NILM (Non-intrusive Load Monitoring) realization method, so as to recognize multiple types of load electric appliances in the NILM system and achieve the purposes of expanding the compatibility breadth of the system and improving the precision. The method comprises steps: data are acquired; the system prepares training data according to a selected load electric appliance; the system uses a specific architecture based on a deep neural network to complete training and modeling on the type of the load electric appliance; and the system completes the load electric appliance recognition process through the well-trained architecture. A complete training data set is selected, and good performance is achieved inthe modeling of electric appliances; in consideration of the compatibility of recognition of most electric appliances, the recognition performance of a two-state electric appliance is enhanced; and the method can be promoted to be used in a system in no need of high-end hardware to acquire data.

Description

technical field [0001] The invention belongs to the technical field of information and communication, and in particular relates to an effective method for realizing NILM. Background technique [0002] Facing the increasingly serious problem of energy shortage and the current situation of increasing electricity consumption year by year, the energy-saving transformation of electricity consumption and the development of smart grid technology have always been research hotspots, so non-intrusive load monitoring (Non-intrusiveLoad Monitoring, NILM) Technology, the concept model of monitoring and managing the electricity consumption of customers is proposed. [0003] The NILM system can detect equipment that needs maintenance and provide equipment-specific feedback to consumers, so that users can reasonably arrange the operating status of related electrical equipment. However, the current NILM method still needs to be improved in terms of recognition performance and coverage of el...
