摘　　要：随着新能源的快速发展和以新能源为主体的新型电力系统的快速建设,现代电力系统动态特性及同步稳定内涵愈加丰富复杂.本文首先简单回顾传统电力系统的发展历程及新型电力系统的研究现状;然后,基于整体论与还原论相结合的研究思路,根据新型电力系统多时间尺度的特性,分别在各个时间尺度(包括交流电流控制、直流电压控制和机电时间尺度)建立含永磁同步风力发电机、双馈式感应风力发电机和光伏3种典型新能源装备(节点)以及交流输电线路(网络)模型,并分析节点与网络的机网接口关系,尝试建立新型电力系统动态模型体系;最后,讨论和揭示新型电力系统同步稳定内涵.本文将有助于加深研究人员对以新能源为主体的新型电力系统动态的基本认识,促进电气工程、复杂系统及统计物理相关专业跨学科研究和交流.With rapid development of renewable energy and acceleration of construction of renewable-dominated new-type power systems,dynamic characteristics and synchronous stability of modern power systems become ever more complicated.This review will briefly introduce the development of traditional power systems and research status of renewable-dominated new-type power systems.The holism and reductionism are combined;three typical renewable energy equipment(nodes)including permanent magnetic synchronous generator,double-fed induction generator,and photovoltaic and AC transmission line(network)models are established within three timescales(including AC current control,DC-link voltage control,and electromechanical timescales)according to multi-timescale characteristics of new-type power systems.Machine-network interface relationship between nodes and network is uncovered.The dynamic model framework of new-type power systems is established.Finally,synchronous stability mechanism of new-type power systems is revealed.This work helps to understand dynamics of renewable-dominated new-type power systems and promote interdisciplinary collaborative research among electrical engineering,complex systems and statistical physics on these fundamental problems.
