A Newton Power Flow for Study Purpose

Abstract The Newton power flow 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 purpose a less complicated but fast Newton power flow algorithm is presented. A great deal of unnecessary computation is exempted in the algorithm simply by adding some selection actions in the procedure of the Jacobian matrix formation and that of Gauss elimination. The presented method needs a little more running time than the one using sparse matrix techniques, but it is much fast than the one without sparse matrix techniques and can satisfy the needs for study purpose. Experimental results validate the practicability of the presented method.
