Abstract :
The high penetration of photovoltaic systems in low voltage distribution networks can cause power quality problems due to the increased level of harmonics. In this paper an overview of the relevant power quality standards is provided along with an investigation of the harmonics generation in LV networks. Hardware experiments of harmonics measurements of PV inverters are conducted where the influence of the active power output and voltage THD is examined. Different ways of modeling harmonic sources are compared in various simulation scenarios of LV radial networks using the PSCAD-EMTDC software.
