Abstract

This paper presents an efficient decoupled power flow based on line power flows with a view to obtain a reliable convergence and higher computational speed for radial distribution systems. The real and reactive line powers are combined using simple multiplying factors such that the modified set is decoupled into two set of equations without making any assumption on ratios. The proposed method is simple and uses a constant sparse sub-jacobian matrix that needs to be factorised only once for both the decoupled sub-problems; and is solved iteratively similar to FDPF technique. This method is applied on three test systems to illustrate its performance.
