Introductory results of tests of algorithms for recreation of voltage variation with voltage fluctuation indices

The paper presents results of preliminary research on possibility to recreate a variation of voltage in power grid on the basis of recorded values of measures of the variation. This is a complex issue because the voltage changes that occur in real networks are random. Five algorithms have been proposed and their quality has been verified using the obtained values of Pst short-term flicker indicator. Description of the algorithms and results analysis have been preceded by the introduction that aims at short description of selected voltage variation indices.
