“…Similar THD influence and distorted current result for a PV power plant can be found in [8][9][10][21][22][23][24][25][26][27]. Generally, it can be concluded that the overall PV contribution to the total system THD is less than 2% and never exceeds the value of 4 % on the PCC.…”

Significant increase of distributed generation (DG) presence and active distribution network (ADN) development cause changes in distribution network's power quality (PQ), mostly in distorted system voltages and currents. This paper analyses harmonics generation from multiple DG types, such as solar and biogas power plants, and simulates harmonic interactions in ADN in order to identify potential PQ issues. Each harmonic source observed in this paper was modelled according to IEC 61000 with the model parameters provided by power quality measurements in the real system on several DG power plants and passive consumer nodes. A harmonic load flow is performed on a detailed ADN model for different presumed DG expansion scenarios that indicate the complexity of the DG impact on the AND's PQ. Quantitative and qualitative graphical presentation for cumulative and the most significant ADN nodes is given and the assessment for the potential ADN development based on PQ indices is proposed.

This paper presents the impact of photovoltaic power plants on distribution grid for voltage stability and economic values by using the central region of Thailand as the simulation system. This region has maximum load of demand with high potential of solar energy development, through varying load characteristic and solar characteristic which used actual existing data parameters from the current photovoltaic power plant in Thailand. Besides, the selected central region system without photovoltaic power plant is simulated as a base case then the contained photovoltaic power plants are also installed to investigate the impact of each case on distribution grid in term of the voltage stability and the total system energy losses by varying six connected buses and three installed distance locations. The simulation results show that the optimal location of photovoltaic power plant can enhance the economic operation of distribution utility over 12.3 million units a year at the same time the voltage stability does not has any effect to distribution grid. Finally, the impact of photovoltaic power plant should be studied before approve the installed location to optimize the social benefit.

“…Existing literature has analyzed the impacts of rooftop and utility-scale PV fleets on representative distribution grids using load flow simulations. Broadly studied parameters include changes in feeder voltage profiles, line losses, power quality, and protection coordination with increasing solar generation [5][6][7]. However, there remains a lack of clarity among distribution utilities on permissible penetration thresholds before upgrades like battery storage and reactive power support become necessary.…”

This study presents a load flow analysis of on-grid rooftop PV installed at Masjid Tablighiyah, Bukittinggi, Indonesia. The analysis was conducted using the Newton-Raphson method and simulated using ETAP software. Two scenarios was explored for the analysis: i) connecting the PV into 20 kV bus, and ii) connecting into 380 V bus. Results obtained showed that grid voltage are meeting the utility standards, with all bus voltages are within ±5% threshold. However, certain nodes have moderately low voltages, suggesting a potential need for pre-emptive measures during peak demand. The power factor performance falls within acceptable ranges (84-91%), indicating reasonable system efficiency. However, there is still needed for continuous monitoring to prevent degradation from harmonic-producing loads. In addition, substation transformers and distribution feeders show ample capacity for future expansions as electricity loads grow. The findings provide a robust baseline for additional grid integration studies, emphasizing the need for further enhancements at weaker nodes to ensure sustained stability and reliability in future demand conditions.
