Abstract
The paper is devoted to the mathematical approaches of the measurements received from Automatic Meter Reading Systems verification. Reliability of metering data can be improved by application of the new issue named Energy Flow Problem. The paper considers demanding energy measurements verification method based on verification expressions groups analysis. Bad data detection and estimates accuracy calculation is presented using the Automatic Meter Reading system data from the Russian power system fragment.

Summary
Electrical Energy (EE) measurements received from Automatic Meter Reading (AMR) systems are used to provide financial settlements on EE markets and in calculations of various technical and economic parameters for solving power system development and planning. Rapid bad data detection is a difficult task that allows to identify AMR complexes with errors that exceeds the maximum allowable limits and to locate the potential sources of commercial EE losses. EFP allows to determine EE flows and technical losses on all elements of equivalent circuit using EE measurements and equivalent circuit parameters. SE theory methods adopted to EE measurements in the frameworks of EFP allows to solve a variety of tasks such as determining the required amount and optimal location of AMR complexes for observability provision [12], determining the sources of EE commercial losses. This paper presents the method of Verifying Equations (VE) for demanding energy measurements verification
