In this paper five different control strategies for grid tie inverter in PV based DG systems have been implemented in MATLAB/Simulink for comparative analysis puropose to evaluate the performance. The control strategies are “inner loop PI controller with outer loop PI controller in NRF”, “Inner loop PI controller with outer loop PI controller in SRF”, “inner loop PR controller with outer loop PI controller”, “inner loop Hysteresis controller with outer loop PI controller”, “inner loop Repetitive controller with outer loop PI controller”. The performance have been evaluated in both static and dynamic conditions and from the results it is evident that PI controller in SRF, PR controller and Repetive controller perform best in both static conditions as well as in case of disturbances coming in either from PV side or grid side.
