Current-Balancing Driven Internal Voltage Motion Model of Voltage Source Converter in Stationary Frame: A Physical Modeling Method in Current-Control Timescale
摘要
Abstract
As renewable generations,flexible AC and DC transmission getting widespread applications in power systems,semiconductor based flexible power conversion devices' states motion have more impacts on system dynamics in current-control timescale.To analyze the dynamic issues of power electronics dominated power system in current-control timescale,this paper proposed a current-balancing driven internal voltage motion modeling method.Based on the proposed modeling method,a current-balancing driven internal voltage motion model of voltage source converters (VSCs) was carried out in stationary frame.By analyzing the dynamic relation between the key states and its physical description which is realized by the equivalent of a controlled current source and virtual energy storage,it is able to uncover the VSC dynamic characteristic in current-control timescale,which contributes to the system stability analysis.The Matlab/Simulink based simulations show the model correctness and analyses effectiveness.关键词
