%0 Journal Article %T Impact of Thyristors Controlled Series Capacitor Devices and Optimal Power Flow on Power Systems %A Fatiha LAKDJA %A Fatima Zohra GHERBI %J Leonardo Journal of Sciences %D 2010 %I AcademicDirect %X This paper presents an algorithm, for solving the Optimal Power Flow problem with flexible AC transmission systems (FACTS). The type of FACTS devices is used: thyristor-controlled series capacitor (TCSC). A method to determine the optimal location of thyristor controlled series compensators has been suggested. The proposed approaches have been implemented on an adapted IEEE 26 bus system. The simulation results are discussed to show the performance of the proposed algorithm and our FACTS programmer simulator technique, which are compared with TCSC and without TCSC. %K Optimization problem %K Power Flow %K Optimal Power Flow %K FACTS devices %K TCSC %U http://ljs.academicdirect.org/A17/145_157.pdf
