Therefore, the hybrid ac/dc microgrid architecture is of more value for smart building than single ac or dc forms . In the traditional microgrid, conventional power transformers are utilized and DGs are connected to network via power inverters, which would lead to inefficient control, complex structure and high cost.
MMC-SST based hybrid AC/DC microgrid architecture is presented for smart building. Power between AC and DC microgrids is allocated by hybrid power droop control. The internal mode control (IMC) is applied in the stage control of MMC-SST. The STATCOM mode is designed to adjust reactive power of ac microgrid dynamically.
There are ac, dc, and hybrid ac/dc microgrid. However, the single form of dc or ac microgrid cannot realize the efficient utilization of DGs and cannot meet the diversified demand. Therefore, the hybrid ac/dc microgrid architecture is of more value for smart building than single ac or dc forms .
Fig. 3 shows the diagram of grid-connected mode of the hybrid ac/dc microgrid for smart building. In the grid-connected mode, the ac microgrid and the dc microgrid are connected to the medium voltage distribution network via the MMC-SST. In this mode, the ac microgrid and dc microgrid are considered as a whole, i.e. the hybrid ac/dc microgrid.
