直流微电网已经成为下一代小规模电力网络，其中线路阻抗非常低。这种现象会导致微电网中的大电流，即使是轻微的电压变化;因此，对于潮流控制器来说，具有更快的瞬态响应和精确的潮流控制至关重要。本研究以多电平换流器作为潮流控制器，以实现直流微电网的高速高精度潮流控制。输出滤波器可以很小，因为使用了多电平转换器。本文还提出了一种多电平变换器输出LC滤波器的设计，以满足电流涟漪的要求。我们的实验验证了一个多电平转换器与一个较小的滤波器可以实现高速和高精度的潮流控制低线路阻抗条件相比，传统的两电平转换器。
DC microgrids have been emerging as next-generation small-scale electric power networks, where the line impedance is very low. This phenomenon causes large currents in the microgrids, even for a slight change in voltage; therefore, it is critical for a power flow controller to have faster transient response and precise power flow control. In this study, multi-level converters are applied as the power flow controllers to realize high-speed and high-precision power flow control in a dc microgrid. The output filter can be small, as a multi-level converter is used. This paper also presents the design of the output LC filter of a multi-level converter to satisfy a requirement of current ripple. We experimentally verified that a multi-level converter with a smaller filter can realize high-speed and high-precision power flow control for low line impedance conditions compared with the conventional two-level converters.
