This paper presents a Synchronized Phasor Measurement Unit (PMU) based controller to support the coordination and operation of a high-capacity high-voltage direct current (HVDC) macrogrid transmission for the continental US. The proposed controller allows for optimal scheduling of each segment of the multi-terminal HVDC network under normal and contingent conditions, while considering minimum levels of frequency response requirements. The performance of the proposed controller is tested on a 100,222-bus representation of the US Eastern and Western interconnections. Results show that a centralized PMU-based controller improves the frequency nadir of the HVDC macrogrid under contingency conditions by 25.9%. Furthermore, the primary frequency response (PFR) of the HVDC macrogrid is increased by 33.4%. The performance of each interconnection under the largest credible contingency conditions is also discussed.

基于同步相量测量单元的中央控制器，用于美国大陆高容量 HVDC 宏电网的正常和应急运行


本文提出了一种基于同步相量测量单元 (PMU) 的控制器，用于支持美国大陆大容量高压直流 (HVDC) 宏电网传输​​的协调和运行。所提出的控制器允许在正常和偶然条件下对多端高压直流输电网络的每个部分进行优化调度，同时考虑最低水平的频率响应要求。所提出的控制器的性能在美国东部和西部互连的 100,222 总线表示上进行了测试。结果表明，基于 PMU 的集中控制器将应急条件下 HVDC 宏电网的频率最低点提高了 25.9%。此外，高压直流宏电网的一次频率响应（PFR）提高了33.4%。还讨论了最大可信应急条件下每个互连的性能。
