Sharing of the loading of asynchronous ac microgrids connected through dc microgrids
Hybrid configurations of the ac/dc microgrids are considered in this paper. It is shown that the asynchronous ac microgrids connected through dc microgrid might not achieve the desired sharing of the loading in each subgrid. Usage of a global loading index in dc microgrid is suggested to overcome differences of the dc loading seen at different points of the dc subgrid, which indirectly assists in reaching the required loading between the ac subgrids. The simulation study conducted in the Matlab/ Simulink environment illustrates the existing problem and verifies the effectiveness of the implemented solution.
