Research on Construction Methods of Transient Security Region of AC/DC Hybrid Power Grid

Abstract

In order to study the AC/DC hybrid system transient stability assessment methods, this article is based on the New England 10 machine 39 node communication system after modification of AC/DC mixed system, the use of PSD - BPA software, to pure AC system and AC/DC hybrid system of AC busbar three-phase short-circuit fault transient stability of the numerical simulation analysis, and uses Matlab to solve its active power injection space transient security region.
