Nonlinear control scheme for VSC-HVDC transmission systems
2008 12th International Middle-East Power System Conference, 2008This paper presents a nonlinear control scheme for VSC-HVDC transmission system. The design of the proposed nonlinear controller has been performed in a rotating reference frame fixed to the grid voltage vectors. The controller is designed to provide high dynamic performance and complete decouple control of active and reactive power.

Simplified Modeling of VSC-HVDC in Power System Stability Studies
IFAC Proceedings Volumes, 2014Abstract This paper presents a simplified modeling approach for a voltage source converter based high voltage DC transmission line (VSC-HVDC) for use in power system dynamic studies. In the AC grid sending-end and receiving-end converters (SEC and REC) of the HVDC system are represented by controlled Thevenin sources.
