Abstract :
This paper presents a Matlab/simulink model of grid-connected photovoltaic (PV) system, including a PV array, a control system, a distribution network and a load. Based on the accurate modeling system, optimum control and stability analysis are studied. The current control strategy can regulate the current at the point of common coupling to achieve the power factor control. The voltage control strategy is used for the PV output voltage to achieve closed-loop control, which can smoothly and quickly track the maximum power point of PV array. Finally, an eigenvalue analysis is carried out on the linearized model of the overall system to determine the robustness of the proposed control strategy. The simulation and analysis verify the effectiveness of the proposed algorithm, and demonstrate that the proposed control system has good static performance.
