Electronic-smart meters are increasingly installed in electricity networks of many countries. In several cases, their operation in parallel with photovoltaic inverters and other powerelectronic devices can result in measurement errors reaching up to 45%. In practice, this problem cannot be tackled by current standards due to the gap in standardization of electromagnetic immunity and emissions in the 2-150 kHz range. This paper provides a comprehensive review of international and national standards, guidelines, technical reports, and papers on this challenging electromagnetic-compatibility issue highlighting the gap in the 2150 kHz range. The ongoing standardization activity to establish both emission and immunity levels and suitable testing procedures is described in detail. Laboratory setups for testing the immunity of smart meters and the emissions of grid-tie inverters are described and experimental results to validate the suitability of the proposed approaches are presented.
