The grid integration of a huge number of photovoltaic systems in existing low voltage grids leads to new challenges in ensuring the required power quality. The objective of this thesis is the analysis and modelling of the perturbations harmonics and flicker coming from photovoltaic systems. Furthermore, a simulation model to characterize unintended reactive power flows of photovoltaic inverter systems - including a stated power factor of one - and to reproduce the real grid parameters with a higher accuracy is introduced. Consequently, this thesis makes a contribution for an effective and reliable grid integration of photovoltaic systems.
