Bi-directional Multiport Converter for Utilizing Green Base Stations as Virtual Power Plant

In recent years, virtual power plant mechanisms that contribute to adjusting the power supply and demand by integrating and controlling energy resources on the customer side have drawn attention. On the other hand, NTT DOCOMO has deployed Green Base Station(G-BTS) equipped with solar panels and high-capacity, high-density lithium-ion batteries, and is working on securing backup in the event of a disaster and reducing power costs. In this paper, in order to use the G-BTS as a virtual power plant, we examined the system configuration and control method that assumed the power cooperation between multiple stations, and confirmed the various operations required for the power cooperation by the actual machine verification.
