ABSTRACT

In this paper, a hierarchical virtual inertia control technique for a bidirectional DC–DC converter is proposed to enhance inertia of an isolated DC microgrid through the DC bus voltage regulation. The transient and steady-state performance of the DC microgrid, in terms of the DC bus voltage regulation, is enhanced with the implementation of the proposed hierarchical virtual inertia control. The DC microgrid is simulated under the variation of both source and load to verify the effectiveness of the proposed control technique. The results show that the DC bus voltage profile is improved during both transient and steady-state operation.

使用分层虚拟惯量控制增强隔离直流微电网的惯量

摘要

在本文中，提出了一种用于双向 DC-DC 变换器的分层虚拟惯性控制技术，以通过直流母线电压调节来增强隔离直流微电网的惯性。直流微电网在直流母线电压调节方面的暂态和稳态性能随着所提出的分层虚拟惯量控制的实施而得到增强。在源和负载变化的情况下对直流微电网进行了仿真，以验证所提出的控制技术的有效性。结果表明，在瞬态和稳态操作期间，直流母线电压曲线得到了改善。
