Abstract (2. Language): 
The continuous growth in electrical energy demand and pressing need for better quality of service has necessitated the need for continuous radial distribution network analysis. Power flow analysis forms the bases of network reconditioning for safety and reliability. In this paper, an improved Backward-Forward Sweep (BFS) technique for power flow analysis is achieved by breaking the conventional solution strategy into a number of logical steps (Matlab sub-functions) that simplifies the problem of node tracing and eliminates the need for sequential node numbering. The sub-functions are then integrated logically via a main-function called ‘RADFLOW’, forming a robust power flow algorithm. A block diagram of the proposed approach and the flow chart of the developed algorithm are presented. Finally, the effectiveness of the developed power flow Algorithm is demonstrated by performing power flow analysis using the 30, 33, and 69 bus standard IEEE test radial distribution networks. The plots of voltage profile and branch power flows of the selected test networks are presented followed by numerical values of the simulation results. The result shows that the proposed approach has a considerable fast rate of convergence and looks promising in solving power flow problems.
