Fundamental Control Methods for Power Flow Control in Next-Generation DC Power Networks

Abstract

This study investigates power flow control methods for next-generation DC power networks. It has been anticipated that numerous distributed generators and energy storage devices will be introduced in next-generation power systems. Therefore, arbitrary and flexible power flow control methods for such power systems are required. In this work, we study a power flow control method that combines node voltage control and additional voltage insertion control on links (link voltage control) for controlling next-generation DC power networks. The effectiveness of the proposed power flow control method is demonstrated by experimental results. It is shown that the proposed power flow control method can be expected to be one of the promising approaches for the realization of next-generation power systems.
