tailieunhanh - Voltage control of grid-connected PV system facing voltage sags

This article presents the development an auto adaptative voltage control integrated into the PV inverters. Facing the voltage sags, this control system allows the voltage at the connection point greater than an admissible voltage threshold of decoupling protection, the connection of PV system is so maintained. The models and simulations are developed in Matlab-Simulink. The obtained results are satisfied. |
