Power quality assessment of PV power plant

The paper discussess the power quality (PQ) assessment in point of common coupling (PCC) of a photovoltaic power plant (PVPP). The analyzed PVPP is a 3-phase 15 kW system localized at Wroclaw University of Science and Technology in Poland. Each phase of the system is different panel technology, as follows monocrystalline (MONO), thin layer copper indium gallium selenide (CIGS), polycrystalline (POLY). The analyzed period of time is 1 year – whole 2018 year. The measurement data was obtained from the stationary power quality monitoring system. In extension, to classic PQ assessment, the statistical analysis was presented.
