Advances in Fast Power Flow Algorithms

The object of this paper is to survey the recent literature on fast power flow algorithms in order to determine the direction of research which is most likely to lead to new, possibly faster and/or more robust power flow algorithms. The analysis here identifies the central idea running through these algorithms. The orientation provided by this review is used to propose some new algorithms. One of the many candidate algorithms proposed is tested on high R/X ratio systems and shown to be robust and to have low execution times when compared with the BX or XB algorithms. It is expected that there exist more algorithms or variations of current algorithms which have similar properties.
