New practicable algorithm dealing with AC/DC power flow calculation

The main solution algorithms which have been widely accepted dealing with power flow problem for AC/DC hybrid systems include simultaneous algorithm and sequential algorithm. The merits and shortcomings of most popular solution methods were analyzed. Problems which may complicate realization of these methods were pointed out. To solve these problems, a new solution method which was based on Newton-Raphson method was proposed. The mathematic conception of this method is very clear and the method is very easy to be used when developing power flow programs because it needs no special process in dealing with DC system. It is simpler compared with other methods when dealing with the change of control strategy of DC system. Example and result of using this method were also been given.
