Design of Grid-Connected Photovoltaic Systems and Technical Requirements in case of Grid Failure
Md. Sazzadur Rahman, Md. Walid Islam, Imtiaz Mahmud, and Md. Mehedi Islam
Growing energy demand and environmental consciousness have re-evoked human interest in grid-connected photovoltaic (PV) systems. This work is focused on the modelling and simulation studies of the dynamic behaviour of a grid connected photovoltaic system. The model is implemented using MATLAB/Simulink with the SimPowerSystems Block Set. This work also presents the results of a comparative study referred to the characteristics of two types of inverters like half bridge and full bridge inverter. Finally, normal and faulty conditions of the photovoltaic generation, especially in the case of grid failure, were simulated and commented. The simulation of the system is developed for testing control algorithm before a real-time implementation.
