Non-Intrusive Load Identification Method Based on Improved KM Algorithm

Abstract: To achieve load disaggregation in non-intrusive load monitoring (NILM) system, a load event matching method based on graph theory is proposed, which is built on the improved Kuhn-Munkras algorithm. In this method, firstly, an adaptive fitting method using time window is applied to detect the load whether it is switched on and/or off. Particularly, to avoid the fluctuation of load signatures, the kernel density estimation is then built by a number of the independent features of the load switching on, including … Show more

“…Considering AMI in a smart grid, smart metering technology enables the prediction of future electricity demands, which can be used by policymakers to make decisions regarding increasing electricity demands. The ongoing development and deployment of smart meters [ 21 , 22 ] has made DSM that deals with ever-increasing electricity demands feasible [ 23 , 24 ]. HEMSs that optimize residential energy consumption in response to DR signals for DSM play an important role in a smart grid.…”
