Grid-Connected Control and Simulation of Single-Phase Two-Level Photovoltaic Power Generation System Based on Repetitive Control

A further research on Grid-connected photovoltaic system was made in this paper. The author made a design for the control of single-phase two-level photovoltaic power generation system based on Repetitive control. In order to achieve a precise control to the Grid-current, the maximum power point tracking and the Grid-connected Inverter`s control were realized respectively. Finally, the whole design for the Grid-connected photovoltaic system has been verified through simulating with the help of MATLAB software. A set of experimental results carried out on a computer is provided to validate the proposed approach. All the work done was of great significance on the development of Grid-connected PV system.
