Review on model framework and synchronous stability of renewable-dominated new-type power systems
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.
