The growing integration of PV units alters system impedance due to inverter-based power electronics, leading to stronger resonance and harmonic interactions. The IEEE 13-bus distribution system was used as a reference model, and MATLAB/Simulink-based simulations were performed to conduct frequency scans, harmonic load flow, and transient analyses under varying PV penetration levels (10%, 30%, 50%). Results show that higher PV ratios cause downward shifts in resonance frequencies, increase total harmonic distortion (THD), and heighten the risk of protection relay malfunctions. Active damping and virtual impedance-based control strategies effectively mitigate these issues, reducing resonance peaks by up to 50%. The study emphasizes the need for coordinated power quality and protection planning in high PV penetration networks.</span></p> |
