Abstract
Problem statement: This study presented a grid connected photovoltaic system with voltage oriented control. This system contains the problem of degradation of photovoltaic power with climatic factors and the problem of synchronization of currents to be injected to the grid. Approach: In order to optimize the photovoltaic energy generation, we developed a new maximum power point tracking algorithm and we use a phase locked loop to solve the problem of synchronization of grid voltage and current. Results: The model of the grid connected photovoltaic system had been implemented in the MATLAB/SIMULINK software and simulation studies have been presented. Conclusion: Results had proved the effectiveness of the proposed system, the utility of the maximum power point tracker and the robustness of the phase locked loop.
