Yljon Seferi has been worked at Federal Institute of Metrology – METAS in Switzerland from 1-April-2016 till 31-October-2016, within the framework of the Joint Research Project Smart Grids 2 number ENG52.
EURAMET (European Association of National Metrology Institutes) through its metrology research programme EMRP awarded to him an “Early-Stage Researcher Mobility Grant” related to the joint research project “Measurement tools for Smart Grid stability and quality”, Smart Grids 2.
Nowadays modern regulations require utilities to guarantee a defined level of power quality, limiting, e.g. harmonics, dips, swells, long and short interruption. The current state-of-the-art is verification and testing of electricity meters following the requirements of legal metrology directives. These regulations do not cover additional power quality functions, which leaves their characterization untraceable.
The goal of his work here at METAS was to perform calibration and type testing of the power quality functions of modern electricity meters («Smart meters»), thereby providing traceability to these functions, and allow grid operators to rely on in real time and to use the functions for grid monitoring. Moreover, power quality measurements should become acceptable as proof in legal disputes.
The mobility grant he received would help metrology infrastructure in our country to acquire the competences needed to further develop it, as well as to successfully participate in the future in research projects in the framework of the European Metrology Programme for Innovation and Research EMPIR.
