Analysis of Impact of Different Distributed Generation Technologies on Harmonics and Short-Circuits in Real Low Voltage Distribution Feeder

In modern power systems, reliable electricity supply is crucial. This study analyzes the impact of small hydro power plants (SHPP) and photovoltaic (PV) systems on a low-voltage network using DigSILENT PowerFactory software tool. Results show that PV systems increase total harmonic distortion (THD), while sHPP reduces THD and significantly increases short-circuit currents during faults. These findings highlight the importance of strategic integration of distributed generation (DG) sources to maintain network quality and stability.
