This paper presents a new algorithm for finding multiple power flow solutions in bulk power systems.By assigning inerement of relative angles,a formula for determining initial voltage voltage value of low soltltion is derived.The program can be executed by adding only a subprogram which is used to determine a proper initial point of low solution to the conventional power flow program.The low power flow solution can be found through one or a few of power flow calculations after the high solution is obtained.Tested on a number of power systems,the glgirthm presented in this paper demonstrates satisfatory effectiveness.The algorithm has advantages of saving CPU time,programming casily and being appropriate for real time application.
