Power Quality Improvement in Power Distribution System with The Placement of Dg Using TLBO Optimization Technique

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 DG (Distributed Generation) 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 to determine the appropriate DG sizes and placements in the distribution network. An IEEE-14 distribution bus system is utilized in the present study as a case study. The suitable size and position 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 balance index, voltage profile, and real power loss reduction. Matlab codes are produced for the TLBO algorithm and the redesigned electrical power system. Findings indicate that the suggested TLBO algorithm is successful in determining the optimal size and location of the needed DG unit. Optimum solution for power quality issues in power distribution system can be obtained using the TLBO optimization technique.
