THE PLACEMENT OF DG USING TLBO OPTIMIZATION TECHNIQUE IMPROVES POWER QUALITY IN THE POWER DISTRIBUTION SYSTEM

Abstract

The distribution system is more susceptible to power losses than other components of the power system. Reduced power losses and higher bus voltages are the outcomes of optimal distributed generation (DG) integration into the distribution system. The TLBO algorithm was developed in this research with the main objectives of reducing power loss and improving the system voltage profile in order to determine the appropriate DG sizes and placements in the distribution network. An IEEE-14 distribution bus system is used in this work as a case study. The appropriate position and size of the DG are chosen using the voltage stability index. The system's overall performance is assessed after the installation of the DG of the ideal size in the appropriate location, along with enhancements to the voltage profile, voltage balance index, and real power loss reduction. Matlab codes are produced for the TLBO algorithm and the redesigned electrical power system. Results show that the suggested TLBO algorithm is successful in determining the optimal size and location of the needed DG unit.
