| 摘要: |
| 随着碳达峰、碳中和目标的持续推进，由火力发电主导的传统电力系统逐步转变为以新能源为主体的新型电力系统。然而，高比例新能源的接入不仅会改造传统机组的低频振荡特征，亦会引入“类机电振荡”。为深入综述该问题，从电力系统潮流、惯量和动态交互的角度，分析了新能源并网对低频振荡的本质影响因素。针对不同的低频振荡类型，系统梳理了对应的产生机理及分析方法。进一步地，在新型电力系统“源-网-荷-储”架构下，对比分析了各类低频振荡抑制方法及其作用效果。最后，针对低频振荡影响因素、振荡机理及其分析与抑制方法的最新研究成果进行总结与展望。 |

| Abstract: |
| With the continuous promotion of the goal of carbon peak and carbon neutrality, the traditional power system dominated by thermal power generation is gradually transforming into the new power system dominated by renewable energy sources. However, the access of high penetration of renewable energy sources may not only transform the low-frequency oscillation characteristics of traditional generators, but also introduce “like electromechanical oscillation”. To present a deep review about the problem, the essential influence factors of grid-connected renewable energy on low-frequency oscillation are analyzed from the perspectives of power system flow, inertia and dynamic interaction. The corresponding generation mechanism and analysis methods are systematically elaborated for different types of low-frequency oscillation. Furthermore, the various suppression methods and their effects on low-frequency oscillation are compared and analyzed under the “source-network-load-storage” architecture of new power system. Finally, the latest research achievements of influence factors, oscillation mechanism, analytical methods and suppression methods for low-frequency oscillation are summarized and prospected. |
