To transfer bulk electrical power over long distances high voltage direct current (HVDC) transmission is currently being considered more and more because of its superior stability performance compared to AC lines whose stability are limited by their line inductances. There is, therefore, a greater need for thorough studies of dynamic interaction between AC and DC systems for use in system design and performance optimization.6.9.
