Abstract :
This paper presents an assessment of the standard successive iterative scheme and strict successive iterative scheme as applied to the fast decoupled load flow, general-purpose version of the fast decoupled load flow, reverse Stott model and fast super decoupled load flow methods. The numerical investigations are carried out on the transmission and distribution systems. Digital simulation studies indicate that there is marginal advantage using the strict successive iterative scheme on the transmission systems. On the distribution systems, the strict successive iterative scheme performs much better. Networks which can not be solved using the standard successive iterative scheme can be solved using the strict successive iterative scheme. The convergence behavior in the case of the fast super decoupled load flow is dependent upon the rotation angle
