An experiment and research platform for DC micro-grid

Aiming at solving the problems that the present DC micro-grid research is still in simulation software or semi-physical simulation platform so that they cannot response the real system accurately, we take the advantage of the devices in our lab to set up a physical DC micro-grid platform, which includes PV cells; wind driven generator; lithium battery pack; super-capacitor; EV research platform; LED and the controllable electric load. They are connected together by the DC-DC convertors to the DC bus, its voltage level is 380V (equaling to the electric supply so that can invert to the grid). In addition, we create its monitoring system using the LABVIEW software. The experiment results show that every convertor can meet their performance well and we can control the power distribute appropriately between the every unit connecting to the DC bus.
