Abstract

Load flow is one of the most important tools in the field of electrical engineering.The load flow of the system participate in the operation and planning side of the electric utilities. Radial distribution system is different from transmission system Transmission system uses the balanced approach which cannot be used in the radial distribution system due to its special characteristics like unbalanced in loading, radial in nature, etc. Due to its said characteristics that Newton-Raphson and Gauss Seidel methods becomes difficult to use. Also, it has been found out that forward-backward sweep method is one of the best performing in radial distribution systems. A forward-backward sweep (FBS) program has been developed using Octave 4.0.0. It has been found that the program is accurate and robust based on the RDAP 2007. The study considered the effects of voltage dependent loads on the IEEE 37 system. The voltage and power parameters have been evaluated. Three cases have been studied-constant power, constant current and constant impedance. It was found out that constant impedance has the highest power loss among the three. Also, for the IEEE 37, as the values of X and Y increases, the power loss also increases. The system and FBS is robust since different X and Y values, the FBS converges.
