Generalized short circuit ratio for multi-infeed LCC-HVDC systems
2017 IEEE Power & Energy Society General Meeting, 2017 The relationship between the short circuit ratio (SCR) and static voltage stability is analyzed in this paper. According to eigenvalue decomposition method, a novel concept named generalized short circuit ratio (gSCR) has been proposed for multi-infeed LCC-HVDC (MIDC) systems to mathematically measure the connect-ed AC strength from the point view of ...

Research on a new scheme of LCC‐HVDC line protection
The Journal of Engineering, 2017 High‐performance protection scheme of the transmission line is very important for the safe and reliable operation of line commutated converter‐based high‐voltage direct current (HVDC) system. The transmission line protection scheme applied in existing projects is lack of reliability, rapidity and incomplete in theory.

IET Smart Energy Systems, Volume 2, Issue 3, Page 181-190, September 2026.Increasing renewable penetration causes out‐of‐step oscillation centres to migrate away from renewable integration points. Two distinct migration modes—continuous drift and large‐range jumps with instability‐mode changes—are identified, providing guidance for adaptive splitting protection in future power systems.
