The solar PV system should be integrated into the distribution network only up to the maximum possible capacity that the network can carry. The maximum penetration level is determined to be 48% by considering the total voltage harmonic distortion and current demand distortion.
From the simulation results conducted, the harmonic distortion level increases when high penetration level of PV system is integrated to the network. Similarly, Farhoodnea et al. in 2012 suggested power quality impact of grid-connected photovoltaic generation system in distribution network.
Similarly, Farhoodnea et al. in 2012 suggested power quality impact of grid-connected photovoltaic generation system in distribution network. They proposed a 1.8 MW grid-connected PV system in a radial 16 bus test system. The total harmonic distortion is determined to be 14.27% which is beyond the standard limit.
The electrical energy demand is steadily growing, and hence, the integration of photovoltaic system to the distribution networks is also dramatically increasing though it has a significant effect on the network’s power quality. The purpose of this paper is to analyze the impact of solar PV integration on the power quality of distribution networks.
The introduction of distributed generation changes the dynamic of the network because power flows may change significantly and potentially in both directions. In other words, the network becomes an active system with power flows and voltages determined by the mix of centralised and distributed generators as well as the load.
