The use of heuristic methods is one of the main advances in research in general since these techniques are capable of adapting themselves to problems for which it is almost impossible to obtain a suitable mathematical model. On the other hand, unlike traditional optimization algorithms, these methods have the ability to incorporate information that is experienced from a particular problem. However, its use in the context of power systems is still in its initial stage, and in this work an application has been presented for the solution of a problem related to the dynamic behaviour of the electrical networks. An effective way of solving the problem of line loss in electrical power systems is through the injection of reactive power at strategic points in the network. We present a brief description of the problem and the most appropriate measures for its solution, as well as some basic concepts about the reactive power flow in transmission lines. It is concluded that an effective way of attacking the problem is by means of FACTS devicesand particularly with the inclusion of the Static VAR Compensator (SVC) and the Thyristor Controlled Series Compensator (TCSC). Because these devices have convenient features for line loss control,voltage control, in addition to being flexible and allow to incorporate tasks such as damping power oscillations. In the proposed work the optimal sizing and locationof SVC and TCSC is obtainedusing Grey Wolf Optimization (GWO)technique,having an end goalof loss minimization. The proposed GWO based method validates using IEEE-30 and IEEE-57 bus systems.Here, the Line losses have been efficiently reduced in both these systems during normal load and overloading conditions with the applications of FACTS devices along with GWO.
