Power system security improvement with optimal placement of FACTS devices using genetic algorithms

The role of the FACTS device in power system security enhancement is very important. But type and location of this device must be defining. This paper presents a novel algorithm for allocation of multi-type FACTS devices based on Genetic Algorithm (GA) using a multi-objective optimization function. Proposed algorithm is tested on IEEE 5&6test system and WSCC 9-bus power system and enhancement security index to more of the double and decrease the loss of system about 25%. With shown the comparison of this paper results and result in a recent paper, indicate the ability of proposed method to enhancement of power system security.
