Flexible AC Transmission System (FACTS) devices play a vital role in improving the static as well as dynamic performance of the power system. The location and size of these devices play a major role in deciding the extent to which the goal of improving the system performance is achieved in a cost effective manner. In this paper, an objective function comprising the cost, line loadings and load voltage deviations is proposed; weights assigned to them decide their relative importance. PSO technique is applied for solving the problem and the effectiveness of the proposed method is tested on IEEE 14, 30 and 57 bus systems.
