Small-Signal Stability Analysis of the LCC-HVDC System With a STATCOM Based on Grid Strength
Static synchronous compensators (STATCOMs) can typically provide voltage support for the line-commutated converter high-voltage direct current (LCC-HVDC) system in weak grids. However, the interaction between STATCOMs and LCC-HVDCs via ac grids may cause sub/super-synchronous oscillations that can degrade system stabil...
