This paper presents Particle Swarm Optimization (PSO) based approach for the allocation & coordinated operation of multiple FACTS (Flexible AC Transmission System) devices for the economic operation as well as to increase power transfer capacity of an interconnected power system under different loading condition. The PSO based approach is applied on IEEE 30-bus system. The system is reactively ...

This paper describes a method of assessing the value of controllable devices such as Flexible AC Transmission Systems (FACTS) in a liberalized electricity market. A sophisticated algorithm using ac optimal power flow (OPF) is often unnecessarily detailed for the purpose of valuating such projects. Input parameters such as expected future generation mix is hard to guess and error prone. Therefor...

One of the best flexible AC transmission system (FACTS) is unified power flow controller (UPFC). As it gets more benefit from both real and reactive transfer, used in for controlling transmitted power. The UPFC controls on side system. When as well set tries to follow command by using proportional integral (PI) controller. But some systems PI controllers cannot produce proper due oscillations. ...

Today’s changing electric power systems create a growing need for flexibility, reliability, fast response and accuracy in the fields of electric power generation, transmission, distribution and consumption. Power system networks are complex systems that are nonlinear, disturbances and faults. It can be accomplished by improving the voltage profile, enhancement of voltage stability and by reduci...

The Flexible AC Transmission System (FACTS) in a Power System improves stability, reduces the cost of generation, losses and also improves loadability of the system. In order to use FACTS devices in a Power system to maximum extent, optimal location of FACTS devices is an important consideration. This paper presents the optimal location of series FACTS device for eliminating or minimizing the l...
