Study of Seamless Microgrid Transition Operation Using Grid
Abstract—This paper investigates operational techniques to achieve seamless (smooth) microgrid (MG) transitions by dispatching a grid-forming (GFM) inverter. In traditional approaches,
Furthermore, a seamless switching control strategy for grid-connected and islanded operation modes of the microgrid system is introduced. Finally, the effectiveness of the proposed method is verified using the Simulink simulation platform and a hardware-in-the-loop experimental simulation platform.
The switching process, however, may introduce transient voltage and frequency fluctuations, causing voltage and current shocks to the grid and potentially damaging devices and systems connected to the microgrid.
The technological and economic advantages of microgrid hinge on the seamless switching between islanded operation and grid-connected operation . The switching can be implemented under the dual mode or signal mode.
Finally, the combination of auto-synchronization control and multiple synchronization control improves the success rate of switching from the islanding condition to the grid-connected condition. The on-site test results of an actual microgrid project verify the effectiveness of the proposed control strategy.
