Application of Simulates Annealing Algorithm for Optimal Location and Sizing of FACTS Devices Considering System Losses and Voltage Division

Abstract

 In the last period, power demand has increased extraordinarily while the widening of power generation and transmission has been harshly limited due to environmental restrictions and limited resources result in inevitable challenges like high losses, overloading, low power quality and exaggerated power transfer along transmission lines, voltage sensitivity, voltage profile problems and reliability problems. Flexible alternating current transmission system (FACTS devices) is applied to maintain adaptable operation of the power system from  power generation field to the distribution field, FACTS devices plays an significant role in promote the dynamic and static behavior of power systems. One technique to hold the power system with minimal losses and improved system voltage profile is to employ FACTS. However, FACTS type, location, and capacity should be optimized to maximize the resulting service. This paper debate how FACTS can be hired to get better the voltage profile and reduce the cost of FACTS, the system loss, in the power network. A soft computing method such as Simulated Annealing (SA) algorithm is used to determine ideal location and size of FACTS device.
