# Performance Enhancement of Distribution Network by Optimal Placement of Multiple Capacitors Using FKBC

- 10 Downloads

## Abstract

The outdated existing electrical infrastructure and shortage in power generation causes complex operation and poor performance of electrical distribution networks. This results in low voltage profile, huge T&D losses, load shedding, and poor power quality of supply. To address these problems several researchers are working across the globe. The many techniques, algorithms, devices, online analysis of power system softwares are introduced to overcome these issues by taking quick corrective measures. In this paper, enhancement of voltage values and minimization of total power loss are taken as key objectives. The placement of multiple capacitors is used for compensation of required reactive power using fuzzy knowledge-based controllers. The proposed methodology is tested on IEEE-15 bus and IEEE-33 bus radial networks. The obtained results are satisfactory in improving the overall enhancement of the voltage profile.
