This paper presents the modeling of the major electronic components of a single-phase gridconnected photovoltaic system. Besides, the control strategy of DC/DC converter is proposed in order to maximize the power from the photovoltaic generator and stabilize the DC output voltage. The gridconnected inverter transforms the power from PV to the grid by keeping constant DC voltage. Controlling separately active power and reactive power is applied to the inverter. Modeling and simulation results which are performed on the Psim software have demonstrated the effective control and dynami response of the grid-connected photovoltaic system.
