摘要

This study proposes a dual-stage cascaded operational control to attain a seamless transition of a standalone microgrid to a grid-connected microgrid system. In order to safeguard the microgrid's stability, the strategy incorporates a bi-directional converter. A dynamic reference frequency loop-based resynchronisation controller is proposed to control the operation of the bi-directional converter. The stage-I operates to maintain the converter end system parameters equal to the utility. This creates a pseudo-equalisation between the converter connected microgrid parameters and the utility. As a result, the simultaneously operating synchroniser controller switches the resynchronisation switch. The stage-II of the proposed strategy addresses the transition controller, which switches the microgrid's mode of operation from standalone mode to grid-connected mode. The grid connected bi-directional converter-based microgrid builds up its parameter equal to the utility. When microgrid builds up to a level that it satisfies the set values of the bypassing controller, it signals the bypassing switch (BS) to operate. In this study, the BS plays an essential role in bypassing the bi-directional converter. The test system designed to study the proposed strategy is simulated on the podium of Matlab 2015b/Simulink.
