Abstract :
A comparative evaluation of a simultaneous and a sequential ac-dc power flow algorithms for a multi-terminal voltage source converter (VSC) based high-voltage direct-current (HVDC) transmission system is presented in this paper. Approximate converter losses are taken into account, using a simplified converter loss model. The algorithms are tested with different modes of VSC operation. The power flow solution is verified with the steady-state operating point in PSCAD.
