Enhance the Voltage Profile and Minimize Power Loss of Radial Power System

In order to analyze the power flow in radial distribution systems, this paper suggests a backward/forward sweep method. High R/X ratios and radial structure characterize the distribution system as a result, the distribution system causes the Newton-Raphson and fast-decoupled methods to fail. One of the best methods for the load-flow analysis of the radial distribution system, the proposed method presents a load-flow study using the backward/forward sweep method. This method can be used to calculate voltage magnitudes at each bus node as well as power losses for each bus branch. The IEEE 33-bus Radial Distribution System has been used to test this method, and MATLAB has been used to produce efficient results. A small power plant known as distributed generation (DG) is attached to a distribution system load in order to enhance the voltage profile, voltage regulation, stability, lower power losses, and increase economic return. The DG can be placed in the best possible way to get the aforementioned benefits. The ideal DG placement and size are determined using a forward-backward algorithm. The algorithm has been put to the test on 33 bus test systems, and the outcomes have been contrasted with those of another evolutionary algorithm. The suggested algorithm with the DG unit operational produced the best results.
