Abstract—In practical installation of FACTS in the power system, there are three common requirements as follows:
What Kinds of FACTS devices should be installed?.
Where in the system should be placed?.
How much capacity should it have?.
This paper focus on the first two of these requirements.
Choosing the type of FACTS devices and deciding the installation location and control of FACTS. We presented a simple algorithm based in heuristic and practical rules to seek the optimal location of two types of FACTS, shunt compensation ‘SVC’ and series compensation ‘TCSC’. The system loadability and loss minimization are applied as a measure of power system performance. Results show the impact of optimal operating points of FACTS (SVC and
TCSC) devices under various conditions of power system.
The proposed methodology to install and operates facts devices properly is verified on the 9-bus system where
FACTS devices operated under normal and abnormal condition. Key words —Power flow, Static Voltage Stability, FACTS,

I. INTRODUCTION
The capacity of transmission lines is becoming the main bottleneck of electricity transmission in the deregulated power industry. The competition of electricity may aggravate loadability of some transmission lines. To meet the load demands in a power system and to satisfy the stability and reliability criteria, the existing
