A Novel Stability Model for AC-DC Combined Simultaneous Power Flow

Conversion of existing high voltage long AC transmission line into combined AC-DC system can bring the benefit stability improvement. Of late, most developments in analysis are simulation based. Sometimes it is difficult to draw a generalized conclusion through result. In this case, an analytical model be perfect tool analyze fault and get concrete decision about future planning. This paper presents for all types fault. Primarily, established at then introducing simple logical modification applicable development models kinds faults, such as; Fault load terminal, sustained line, very close generator bus. To expose efficacy developed two different ways validation process followed optimistic results found
