2. 1. Modeling and Control of VSC-HVDC Links Connected to Weak AC Systems

   Author : Lidong Zhang; Hans-Peter Nee; Alan Wood; KTH; []
   Keywords : Control; modeling; multivariable feedback control; HVDC; power systems; stability; subsynchronous torsional interaction; voltage-source converter; weak ac systems;

   Abstract : For high-voltage direct-current (HVDC) transmission, the strength of the ac system is important for normal operation. An ac system can be considered as weak either because its impedance is high or its inertia is low. READ MORE
