چکیده
Single-phase grid tied inverter is one among types of inverters widely used in photovoltaic generation system due to the advantages they offer. This paper describes model and simulation of such inverter in operation as distributed generation in electrical power system under Islanding Phenomena. The role of current or voltage control and associated mechanism in photovoltaic inverter such as photovoltaic I-V characteristic, maximum power point tracker (MPPT), and other mechanism that involves in power flow and load sharing control are considered. In this study, the goal is to implement the analytical model of a switching grid converter pv system source with current control of a PV grid-connected system under islanding phenomena with the Active Frequency Drift Antiislanding Detection Method. The proposed modeling is implemented by MATLAB/SIMULINK.
