Solar photovoltaic (PV) system installations are rapidly increasing in distribution networks. These PV systems include power electronic devices which have an influence on the power quality of the grid in the form of harmonic distortion. The aim of this study is the harmonic impact of PV systems on distribution networks.
Harmonic problems are common in distribution networks, mainly coming from non-linear loads, transformers and increased use of power electronics equipment [ 1 ]. Solar PV systems use power electronic-based inverters and converters which are becoming a new potential source of harmonics.
Harmonic analysis has been performed through simulations of three different case studies, which are with and without the existence of ambient harmonics in the network. In this paper, these two PV systems, interconnections at a single node and multiple nodes of the network have been taken into account for the characterisation of harmonic levels.
At low PV power generation periods (early morning or evening), the voltage THD levels were in the range of about 0.2–0.4%. However, during peak power periods (sunny and average cloudy days) the PV system produces voltage harmonics of nearly 1.4%, which is satisfying the IEEE 929 standard limit.
