Review on Optimization Algorithm based Optimal Location and Size of FACTS Devices

Flexible Alternating Current Transmission Systems (FACTS) can manipulate the fundamental components of electrical system used in conveyance and enhance the attributes of the electrical system. The FACTS device provides a solution to some critical problems such as voltage stability, line overloading, power loss, power flow and so on. The FACTS device plays a significant part in heightening operations of the power system that might be static or dynamic and also entails a capital investment. So this paves way for the optimization of FACTS device in terms of position and the size in order to enhance the performance of the power system. This paper reviews on four different FACTS devices in the power system such as series, shunt, combine series and shunt, combine shunt and series devices, which is selected to place in suitable locations to heighten the voltage level and reduce the losses in the power. The effects of FACTS devices on various bus network parameters on the grounds of, generation cost, power loss and voltage stability, etc. are evaluated. This review work motivates the researchers to do further research to improve the size and the location of the FACTS devices in order to reduce the loss in power and maintain a voltage level.
