摘要：
A power flow controller (PFC) that realizes flexible power flow control in DC power networks is investigated herein. In previous studies, an additional node called a compensation node was introduced in PFC. This compensation node is necessary for regulating the link voltage that decreases owing to circuit loss. However, as the compensation node is not directly related to the power flow control, adding the compensation node may increase the cost. In this paper, we propose a link voltage control method for PFC without the compensation node. Adding the current command for the link voltage control to the current command for the power flow control makes it possible to realize flexible power flow control and constant link voltage control without the compensation node. The effectiveness of the proposed method is verified experimentally. © 2021 The Institute of Electrical Engineers of Japan.
