Review of dc–dc converters for multi‐terminal HVDC transmission networks

“…For the majority of this period, the difficulty of power reversal in complex multi-terminal networks based on line commutating converter high-voltage dc (LCC-HVDC) technology has prevented development of generic dc grids with seamless control over the power flow in any of its branches [16]. Moreover, the increased dependency of the LCC terminal on the ac network strength has caused significant concerns regarding ac voltage stability of relatively weak ac networks, especially when large power is being exchanged [8,[16][17][18][19][20][21][22][23][24][25][26]. The emergence of voltage source converter high-voltage dc (VSC-HVDC) in the early 1990s [10,12,[27][28][29][30][31][32][33][34][35][36][37][38][39][40][41][42][43][44][45][46] that can reverse dc power without any difficulty (power reversal is achieved without the need to reverse the dc voltage) has reinvigorated research into generic multi-terminal HVDC networks.…”
