Synchronization, Fault Detection of PV Array and Grid with MPPT Techniques Using MATLAB/Simulink

摘要

In this paper, a solar cell (PV) system with different MPPT techniques connected to grid is introduced. There is a rise in the rapid development of high-penetration solar energy due to an increase in interest as well as investment in renewable energy. There are numerous ways in which a PV array can be interfaced with the grid. The lookup table PV panel with a centralized inverter topology has been developed in this paper. Since solar arrays output varies with change in solar irradiation as well as climate surroundings, the maximum power point tracking (MPPT) algo is adopted in DC-to-DC converter to enable PV arrays system to operate at maximum power point output. In order to control the inverter, the incremental conductance algorithm and fractional open voltage method is employed. Scheme for fault detection and system reconnection after fault is presented and simulated in MATLAB.
