Summary:This study addresses a static variable load for grid-connected photovoltaic system. In order to make the proposed system more improving powers disturbances, the interconnection of grid- photovoltaic assembled a reversible converter. The power circuit is composed of two 75 watts series photovoltaic panels associates to a static variable load with a dc-dc boost converter interconnect an alternative grid via reversible converter controlled by pulse width-modulation technique. In the dc–dc power conversion, the incremental conductance maximum power point tracking is introduced to improve the conversion efficiency of conventional boost converter. Moreover, a simple control system is designed for the current control of the reversible inverter to synchronize the output current to the alternative voltage in the grid and less variation under static load changes. Obtain results by using Matlab/simulink indicates that the present photovoltaic -grid system able to exchange the direction of active powers in the alternative grid for static variable load caused by reversible converter design.
