Load Flow Analysis for Radial and Mesh Connected Distribution Systems

Sathiyanarayanan.T, M. Sydulu

Abstract: Distribution System load flow studies play a vital role in present day scenario. Distribution Load Flow (DLF) are required for demand side management; distribution management system; studies to include dispersed generation; load scheduling; etc. ; for the modern growing distribution systems. DLFs are different from the load flows we use for Power Systems; because of the radial nature of the distribution systems. Also some of the methods need to be modified for weakly meshed distribution system. This paper presents ideas of three distribution load flows; namely Primitive Impedance based Distribution Load Flow (PIDLF) ; Current Injections based Distribution Load Flow (CIMP) and Fast Decoupled Single Matrix Model Distribution Load Flow (SMM). These methods are briefed and tested on IEEE standard 15 bus; 33bus and 69 bus systems and comparative study is carried out based on the converged voltages; phase angles and the number of iterations taken for convergence.

Keywords: Distribution Load Flow, Primitive Impedance based load flow, Current Injection, FDC SMM
