Abstract
The object of this thesis is to present a DC micro-grid simulation test bed with grid-connected function which consists of wind turbines, photovoltaic (PV) panels and fuel cells as distributed generations, lithium-ion batteries and ultra-capacitors as energy storages, and a three-phase grid-connected inverter.
The three-phase grid-connected inverter is equipped with the LVRT (Low Voltage Ride Through) capability which lets the micro-grid be able to ride through grid faults that bring voltages down to a very low level.
This test bed is built by mathematical models in Matlab/Simulink, and the simulation results are showed by human-machine interface in LabVIEW. It is a platform for users to clearly handle the information of the DC micro-grid.
