    Wpływ mikroinstalacji fotowoltaicznych na wybrane parametry jakości energii elektrycznej oraz pracę agregatów w sieci dystrybucyjnej niskiego napięcia
    (Wydawnictwa AGH, 2021) Topolski, Łukasz
    High concentration of single-phase photovoltaic mi- cro-installations on a low-loaded low-voltage distribution feeder often has a negative impact on power quality parameters which leads to automatic photovoltaic inverters shutdown and obstructs distribution network maintenance using mobile power generation units. The paper presents the impact of 2 kW single-phase mi - cro-installations on voltage profile and voltage and current un- balance in a low-voltage distribution network. The paper also discusses cooperation of a mobile power generation unit with micro-installations and presents the results of measurements of mitigation effectiveness of the negative impact of micro-instal- lations on voltage quality using a balancing transformer and a se- ries automatic voltage regulator with independent phase voltage regulation.
