The load flow analysis is one of the powerful tools by which an AC-DC system is analyzed both for planing and operation strategies. This thesis presents the development of an algorithm suitable for application in the load flow analysis of AC-DC systems. Three methods of controlling a DC line have been described in this report. A simplified version of the AC-DC load flow method with all of capacities of established fast decoupled methods is shown to have the best qualities of sequential solution AC-DC combined. Next, important features such as discrete taps, distinction between scheduled voltage and scheduled angle controls, fixed taps and extended phase controls, and current limits are incorporated to enhance the versatility method. These algorithms have been tested on a EGA T system and the computed results have been presented.
