【 摘 要 】

In this work, a complete model for the integration between the Photovoltaic Distributed Generation System (PV-DGS) and the utility grid is simulated by MATLAB/SIMULINK. The aims of this study are to provide active power of a given feeder and to improve the output power quality from the PV-DGS unit. To achieve these aims, Two PV-arrays with total power yield equal to 200 KW are modeled. The maximum power point tracking based on the perturb and observe technique is used to control the DC-DC converter. The voltage source converter is controlled to allow the system to operate in different modes. These modes are the unity output power factor and the reactive power compensation. Different control techniques have been applied including the conventional PI controller as well as the intelligent optimization tuning. A complete comparison between both techniques has been introduced and analyzed.
