This paper exhibits a Comparative study among the different controllers used for PV grid integration and its low voltage ride through (LVRT) capacity enhancement. PV system integration performed through DC-DC converter, DC-AC converter, DC link and DC link capacitor. The FRT capability of grid integrated PV system is analyzed using PI controllers, PR controllers and Fuzzy logic controllers. The test system FRT capability is tested in MATLB/ Simulink software environment. The FRT capability of fuzzy based controller is greater than among the three controllers used for inverter control during integration. The fuzzy logic controller is faster in response and it has an ability to maintain error closer to zero. Due to this it can enhances system stability by reducing maximum peak overshoot and time taken to stable and improves the system performance.

Keywords- Photovoltaic (PV) power systems, Power system dynamic stability, power system control, adaptive control, Proportional Resonant and Fuzzy control, low voltage ride through (LVRT)
