Mesh-based architecture for DC microgrid control to achieve accurate current sharing among converters

Various examples are provided related to DC microgrid control. In one example, a system includes a mesh DC microgrid network having at least 4 microgrid DC nodes. The mesh DC microgrid network can be organized as clusters of three node DC microgrid systems, where each cluster include three of the at least 4 microgrid DC nodes. In each cluster, one of DC microgrid nodes is a pivot node that links remaining clusters together within the mesh DC microgrid network. Each DC microgrid node of the mesh DC microgrid network is directly connected to the pivot node. In another example, a mesh DC microgrid network includes one or two remaining microgrid DC nodes directly connected to a pivot node by a tie-line including a tie-line current sensor. One or more converters at the remaining DC microgrid nodes can be controlled using feedforward control with droop control using tie-line current sensor information.
