新能源电力系统暂态频率稳定分析与调频控制方法综述

Under the "carbon peak and carbon neutrality" strategic goal, China will build a renewable-dominant power system. The moment of inertia and frequency regulating capacity of the renewable-dominant power system are reduced, and the fault disturbance power is increased, which threatens the transient frequency stability. In order to meet the requirements of transient frequency stability, it is necessary to explore new frequency regulation control methods. The current frequency regulation control methods and the analysis models they rely on are difficult to apply to renewable-dominant power systems. In order to better understand the transient frequency stability problem of renewable-dominant power systems and prepare frequency regulation countermeasures, this paper summarizes and prospects the research status of transient frequency stability analysis and frequency regulation control methods. First, the existing transient frequency analysis models are summarized. Then, the research status of frequency regulation control methods is sorted out from the system and plant levels, and the applicable characteristics of different frequency regulation control methods are summarized from the analysis basis. Finally, the characteristic changes of transient frequency stability analysis and frequency regulation control of renewable-dominant power systems and their effects are summarized, and the possible future development ideas are prospected.
