Abstract


Objectives: In this paper an improved algorithm for load flow analysis of Radial Distribution Systems (RDS) is presented. The algorithm incorporates probabilistic variations of line and load data along with composite loads. Methodology: The algorithm uses Simple Backward and Forward Sweep based method for solving RDS and has further been modified to solve distribution systems with Distributed Generation (DG). Findings: This Improved algorithm for load flow analysis is tested on standard RDS and considerable promising results have been delivered for the system having Distributed Generator for improving the voltage profile and reduce the losses. Novelty/Improvement: The results obtained are exemplary that confirms usefulness of the algorithm and can have significant impact on future planning and operation purposes of unbalanced RDS.
