一个国家内或邻国之间的长距离大容量电力传输需求以及海上风电场数量的快速增长，增加了高压直流链路的应用。除了HVDC系统的可控潮流功能之外，还可以采用先进的控制器来扩展其功能，以改善底层AC系统的动态和暂态稳定性。本文比较和批判性地评估直流附加控制器策略，以提高交流系统的稳定性。本文对每种控制器类型的控制器设计过程作了初步的解释，并对它们在阻尼区域间振荡方面的应用作了简要的比较。
Bulk power transfer requirements over long distances within a country or between neighboring countries as well as rapid increase in the number of offshore wind farms, have increased the application of high voltage DC links. Apart from the controllable power flow function of HVDC systems, advanced controllers can be employed to extend their functionality for dynamic and transient stability improvement of the underlying AC systems. This paper compares and critically evaluates HVDC supplementary controller strategies for improving AC system stability. A Preliminary explanation of the controller design process for each controller type as well as a brief comparison on their application to damp the inter-area oscillations have been presented in this paper.
