Simulation, implementation and testing of three-phase controlled power inverter behavior

With the increase in the use of renewable sources, the study of control schemes for better control of distributed generation systems and grid connection has become very vital to achieve better stability of the system. This thesis provides a study of the control scheme for interconnection between a DC source and an AC grid. A possible control scheme is studied and simulated in Simulink. The system behavior is analyzed by subjecting it to different changes in parameters and grid conditions. . Possible modifications are applied to the scheme enable it to perform in the desired way in case of unsymmetrical grid conditions. The implementation of the scheme is done by using dSpace and Simulink model. Only Low Voltage implementation is performed and tested in this thesis.
