Transient Response Analysis of a Single Phase Roof Top PV With Synchronverter Control

The study proposes a single phase roof top photovoltaic (PV) with synchronverter control wherein the synchronverter behaves similar to that of synchronous generator. Considering the irradiation and climatic changes a battery is used so as provide an uninterrupted supply. The battery works as an ancillary service to the PV system. Further, the behavior of the synchronverter under various voltage and frequency variations is analyzed. To validate the reliability of the synchronverter the paper emphasizes the approach of transient response under unbalanced condition. The dynamic Phasor model of a single phase roof top PV is taken into account to test the behavior of the synchronverter under unbalanced condition and during asymmetrical faults and to check the reliability and efficiency of the same respective simulation is carried out. The detailed model is done by using MATLAB/SimPowerSystem. The results from the load disturbances and asymmetrical faults are verified.
