新型电力系统主动构网机理与技术路径
Mechanism and Technical Path of Active Grid-forming of New Type Power System
摘要
Abstract
With the development of a new generation of"double-high"power systems,the new energy grid-connected conversion system has gradually evolved from a grid-connected type to a grid-connected type.When the new energy units are running in clusters,the grid connection situation will be more complicated.The grid construction capability of the converter needs to be studied urgently,and it is also an important mission for the transformation of electric power.Based on the globality of the internal and external forms of the grid-connected system and the limitations of the performance analysis of the traditional grid-connected conversion system,this paper re-reveals the support mechanism of the grid-connected converter's active grid construction.First,the virtual synchronization technology and network construction mechanism are briefly reviewed.Then,three key technical issues,such as the modeling of cluster grid-connected system,the coupling interaction of multi-machine cluster grid-connected operation,and the energy storage configuration and operation boundary supporting the grid construction capability,are deeply studied.Finally,technical path discussions and judgments are made for the above three key technical issues.The idea of this paper is to attract others and lay a preliminary work for the formation of a systematic theory and practical method suitable for the grid-connected operation of new energy clusters in the future.关键词
