Detecting non-technical losses in electrical networks based on multi-layered statistical techniques from smart meter data

摘要

Methods, systems, and computer program products for detecting losses in electrical networks are provided herein. A computer-implemented method includes computing a consumption estimation for each consumer associated with a network; determining a difference between (i) the consumption estimation and (ii) actual consumption for each consumer; clustering the consumers into a cluster based on a consumption pattern associated with each consumer; determining a level of deviation of (i) the consumption pattern associated with each consumer from (ii) a consumption pattern representative of the cluster; clustering the consumers into two or more clusters based on a consumption pattern during a first interval of time and during a second interval of time; determining, for each consumer, a level of evolution from (i) a first cluster during the first interval to (ii) a second cluster during the second interval; and identifying consumers associated with a given loss within the network.
