Minimizing Power Losses inGreat Electrical Power Systems by Optimal Location of FACTS Devices Using a Genetic Algorithm

Currently,with an increasing in the size of electrical powernetworks and the appearance of unwanted interconnections,these systems are becoming more difficult to manage and control. However, since the appearanceof new technology FACTS, these systems are becoming very flexible and controllable, offeringa better possibilities for a robust and efficient expansion of power networks by itscapability to control various electrical parameters in the transmission lines. Indeed, the FACTS devicescould increase system capacity and decrease total power losses. This paper describes a new approach to minimize electrical power losses of large electrical systems. The idea, withinstalling FACTS devices in their optimal locations,is to analyze and improve a transmitted electric power with low losses and minimum coast by using Genetic Algorithm as an optimization technique. Moreover, investigating best parameters of each device is taken into account in this work
