| 摘要: |
| 在高比例新能源接入和电力电子设备广泛应用的背景下，电力系统的频率稳定受到了严峻挑战。针对缺乏大型交流互联电网支撑的独立同步电网中的频率失稳问题，研究了国际独立同步电网在新能源高渗透率下所应对的技术措施，并结合南方电网实际提出了建设新型电力系统的技术借鉴路径。首先，调研了爱尔兰岛电网、得州电网和澳大利亚电网在应对新能源高渗透率运行下频率稳定挑战的技术进展。然后，总结了频率稳定措施，包括临界惯量的精准评估及需求优化、惯量在线监测系统的建设、调频资源的新管理方法等方面，并分析了各独立同步电网在频率稳定方面取得的成效。最后，结合南方电网实际情况进行量化分析，为新型电力系统的发展提供技术参考和借鉴。 |

| Abstract: |
| Under the context of a high proportion of renewable energy generation and widespread application of power electronic devices, the frequency stability of power systems is facing severe challenges. To address frequency instability issues of isolated synchronous grids that lack the support of large interconnected AC networks, this paper investigates technical strategies adopted by international isolated synchronous grids under high renewable energy penetration, and proposes technical reference pathways for developing a new-type power system tailored to the conditions of the China Southern Power Grid. First, the technical progress of the grids of Ireland, Texas, and Australia in addressing frequency stability challenges under high renewable penetration is reviewed. Then, frequency stability measures are summarized, including accurate assessment and optimization of critical inertia, the establishment of online inertia monitoring systems, and new methods for managing frequency regulation resources. The effectiveness of these measures in improving frequency stability in each isolated synchronous grid is also analyzed. Finally, a quantitative analysis is conducted based on the actual situation of the China Southern Power Grid, providing technical references and insights for the development of new-type power systems. |
