摘　　要：在“30·60”双碳目标的引领下,以化石能源为主导的场站逐步转变为以新能源为主导的场站,场站内部电力电子设备也随之逐步增多。然而新能源场站内部电力电子变流器相互作用、相互耦合,致使新能源场站电压/频率稳定性变得更加复杂,因此如何协同控制新能源场站内部的电力电子变流器以维持新能源场站电压/频率稳定,越来越受到研究人员的关注。该文基于变流器的控制策略及新能源场站模型,对目前新能源场站协同控制策略及多机暂态稳定性分析进行梳理以及总结。首先从变流器单机控制策略入手,分析了不同电力电子设备的电气特性及动态能力,明确跟网/构网变流器混合的新能源场站的必要性;其次,总结了目前新能源场站的主要结构及等值建模策略,为后续新能源场站协同控制及稳定性分析提供基础;再次,对多机暂态稳定性分析方法进行总结归纳;然后进一步梳理不同场景下混合场站内变流器协同控制策略;最后对目前混合场站协同控制策略优势和局限性进行总结,为未来研究提供借鉴。Under the guidance of the“30·60”dual-carbon targets,the traditional power system,which is centered around synchronous generators,is rapidly transitioning to a new type of power system dominated by power electronic inverters.The mutual coupling and influence of these inverters make the voltage/frequency stability of hybrid stations with grid-following and grid-forming inverters more complex,necessitating coordinated control of multiple inverters within the station to maintain stability.This paper reviews the current coordinated control strategies and transient stability analy-sis for multi-inverter hybrid stations based on the control strategies of inverters and the model of hybrid stations with grid-following and grid-forming inverters.First,the control strategy of individual inverters is presented,the electrical characteristics and dynamic capabilities of different power electronic devices are analyzed,and the necessity of mixing grid-connected and grid-forming inverters in new energy stations is clarified.Second,the main structures and equivalent modeling strategies of current new energy stations are summarized,providing a foundation for subsequent cooperative control and stability analysis of new energy stations.Third,methods for multi-machine transient stability analysis are summarized.Then,the cooperative control strategies of inverters within mixed stations in different scenarios are further organized.Finally,the advantages and limitations of current cooperative control strategies in mixed stations are summa-rized,offering references and insights for future research.
