Modeling & Performance Investigation of PV Integrated IEEE 14 Bus Test System

This paper presents the modeling and performance analysis of Photo Voltaic (PV) integrated IEEE 14 bus test system in MATLAB/SIMULINK software. The performance of designed power system network is tested under varying irradiance, load magnitude and load type scenarios. Simulation results are presented in terms of voltage/power variations and Total Harmonic Distortion at Point of Common Coupling (PCC) to analyze the impact of PV integration on different power quality parameters.Simulation results demonstrated that power quality at PCC is affected and harmonics are introduced in the system because of intermittent nature of PV, inverter characteristics, and also due to the presence of non-linear loads. Therefore, this study recommends the use of more stable and efficient power electronics converters or FACTS devices for improved power quality in PV integrated grid systems.
