The influence of seasonality of microgrids connected to the power system on selected power quality parameters

The article presents an assessment of the parameters of power quality obtained from renewable sources. The assessment was based on the Decree of the Minister of Climate and Environment of March 22, 2023 on detailed conditions for the operation of the electricity system (Dz. U. 2023 r., 819) and the EN 50160: 2010 standard – Parameters of supply voltage in public power grids. The analysis was carried out on the example of actual measurements of power quality parameters. The measurements were made with a Fluke 1760 power quality analyser. The analyser was installed at the point of connection to the renewable energy grid. The article analyses and compares renewable energy sources. The assessment of power quality parameters was carried out on the basis of the discussed analyses. The article presents the influence of seasonality on the parameters of power quality.
