Designs of Fast Decoupled Load Flow for Study Purpose

AbstractThe fast decoupled load flow (FDLF) program which employing sparse matrix techniques needs less computer storage and running time, but makes it harder by modifying the program to adapt to further study such as power system security and continuation power flow. To meet study purposes a less complicated but fast FDLF algorithm is presented. A great deal of unnecessary computation is exempted in the algorithm simply by adding some selection actions in the procedure of Gauss elimination. The presented method needs a little more running time than the one using sparse matrix techniques, but it is much faster than the one without sparse matrix techniques. And it runs as fast as the practical Newton power flow with sparse matrix techniques does. So the presented method can satisfy the needs for study purpose. Experimental results validate the practicability of the presented method
