#### Abstract

Distribution networks transport electric energy to the end user from distribution substations. Power utilities are all the time looking for improved power delivery performance. The performance of the delivery system is measured by the power loss of the system. The increase in power loss increases the operating cost of the distribution system. This paper presents an algorithm to control the power loss of the distribution system. Self Adaptive Hybrid Differential Evolution (SaHDE) technique combined with sensitivity factors has been practiced to find the optimal location and the size of TCSC (Thyristor Controlled Switched Capacitor) devices to reduce the power loss of Radial Distribution System (RDS). The locations of the TCSC devices are found out by the sensitivity factors. The amount of reactive power component generation/absorption by the TCSC devices at the identified locations has been calculated through SaHDE. The effectiveness of the proposed technique is validated through 10-bus, 34-bus and 85-bus radial distribution systems. *Copyright © 2013 Praise Worthy Prize - All rights reserved.*
