optimal location of FACTS devices to improve power systems performance

Abstract

Flexible Alternating Current Transmission Systems (FACTS) devices have been proposed as an effective solution for controlling power flow and regulating bus voltage in electrical power systems, resulting low system losses, and improved stability. Placement of these devices in suitable location can lead to control in line flow and maintain bus voltages in desired level and so improve power system security. This paper presents a novel algorithm for allocation of FACTS devices based on Elitist Non Dominated Sorting Genetic Algorithm (NSGA-II). The proposed algorithm is tested on IEEE 14 bus power system for optimal allocation of multi-type FACTS devices and results are presented
