Summary:
Renewable energy power sources have large quantities of direct current (DC) power, and because most of the loads experienced by these sources also use direct current, there is an increase in attention to microgrids that limit their dependence on the power grid. To benefit DC microgrids, we are developing a virtual grid (VG) system using USB Type-C that supports the USB Power Delivery (PD) standard. In the VG-Hub network, a large amount of power must be synthesized and distributed with as few VG-Hubs as possible. A key problem is how to derive the maximum executable flow to create a VG-Hub network with both the smallest number of VG-Hubs and the largest combined distribution power. Therefore, the purpose of this study is to obtain a graph necessary for discussing the problem of deriving the maximum executable flow based on an arbitrary graph in which multiple VG-hubs are connected. We demonstrate that, by generating a connection matrix that represents the connection status of the power supply and loading it in advance, a graph of the VG-Hub network connected to the power supply and the load could be created.
