Grid-connected distributed generation will affect security, power quality of the traditional power
system. Usually, voltage source inverters (VSI) are controlled to meet the requirements of grid-connected
distributed generation. Key technologies of the grid-connected VSI system are described in this paper. The
filter is analyzed and the design methods given. Meanwhile, the phase-locked loop (PLL) using the unbalanced
grid conditions and low voltage ride-through (LVRT) technology are studied. Based on the theoretical analysis,
a simulation model for the grid-connected Voltage source inverters (VSI) system is built and validated with
MATLAB/Simulink.
