1results about How to "Improve decomposition accuracy" patented technology

This invention belongs to the field of smart grid and load monitoring technology, and provides a multi-task non-intrusive load decomposition method system. The method includes: acquiring the total load data sequence at the input port of the power consumption unit, and inputting the total load data sequence in parallel to a power decomposition branch and a state identification branch; the power decomposition branch processes the total load data sequence to generate a power prediction value for the target appliance; the state identification branch processes the total load data sequence to generate an operating state probability for the target appliance; and the power prediction value and the operating state probability are fused to generate the final decomposed power of the target appliance. This invention, through a dual-branch multi-task architecture and output fusion mechanism, collaboratively optimizes the power prediction and state identification tasks, effectively solving problems such as insufficient long-term dependency modeling, inaccurate capture of diverse features, and power false alarms caused by inconsistent prediction results in existing technologies, significantly improving the accuracy and reliability of load decomposition.
