Uncontrolled power losses caused by electricity thefts in power distribution systems (PDSs) have a detrimental impact on technical and economic performance of these systems. Modern automated systems for electricity revenue metering (ASERMs), which are nowadays widely used for automation and computerization of processes in PDSs, lack digital technologies for separate estimation and monitoring of technical and non-technical power losses. The paper proposes a novel technique and an algorithm for its implementation based on the data obtained from electricity meters that are part of the ASERM structure. In order to ensure the solvability of the identification problem, we introduce the concept of a virtual network model representing the desired state of the PDS in the absence of ETs. The model serves as the basis for deriving algebraic equations. Such equations allow identifying technical and non-technical power losses in three-phase networks. Our research findings aim at further improvement of modern ASERMs and enhancement of their performance and reliability.
