From past decade, the major issues involved in deregulated power systems are branch loading and voltage stability. To address this issue, in this paper an evolutionary programming algorithm was proposed for optimal positioning of FACTS devices. The Evolutionary Programming algorithm considers the FACTS devices and line numbers to generate the population. The proposed approach considered three objectives for optimality such as maximization of branch loading, maximization of the voltage stability and minimization of the power loss. The proposed algorithm's performance is compared with the conventional genetic algorithm and the simulation is carried by MATLAB with different cases. With the simultaneous operations of branch loading, voltage stability and loss minimization, the branch loading is increased by 9.6% and the voltage stability is increased by 2.3% and the loss is reduced by 4.8%. The result shows the performance of the proposed model.
