Expanding functionality of the smart electric grids and increasing amount of local energy accounting devices, smart sockets, etc. in LV power grids urge for innovative methods of metrological traceability. The new methods of calibration must be coherent with the modern monitoring, accounting and control systems of the smart LV power grids. The main key factors of the metrologically reliable and user friendly remote energy accounting as well as identifying and localization of the disturbances in the local LV power grids are the coverage of synchronization of the grid parameter monitoring, synchronization uncertainty between the distributed measurement devices in the smart grid and metrological parameters of the accounting devices. Distributed measurements and their realization possibilities in the LV power grids are the main goal of this project. The remote error monitoring method for the smart energy accounting devices is based on the synchronized short-term energy measurement in the site of remote and reference measurement units. It is known that the reliability of the method will certainly depend on the accuracy of the synchronization but the quantitative impact of the synchronization to the remote monitoring uncertainty was not investigated.
