A Way to Evaluate Segmentation: An Examination of AC Line Elimination in a Parallel AC/DC Transmission System

AC line elimination in a parallel AC/DC transmission system is investigated for segmentation analysis of small scalepower system. The segmentation concept is explained. It is arecently proposed method to ease the planning and operating of current power systems. The rotor angle stability analysis in asegmented power system is studied. Simulations are performed in a two-area test system. The results show that segmentationconcept can be studied through AC line trip parallel to DC transmission
