Abstract

With the growing power demand, the need for innovative and novel methods to operate large interconnected power systems has increased. This reflects more complexity and therefore less secure than before. Hence, modern power systems are more prone to widespread failures. The device that has enhanced the safe and reliable operation of the network and has contributed to capacity augmentation is Flexible AC Transmission System (FACTS). But this is very expensive and must be suitably sized and located to maximize the overall benefit to the system. The paper aims at determining the optimal location and size of the Static Var Compensator (SVC) by optimizing the multi-objective function formulated by different factors that define the system security, namely, voltage deviation, system overload and real power losses. The multi-objective optimization function has been optimized using a Modified Bacterial Foraging Optimization Algorithm (MBFOA). The results are presented and analyzed for an IEEE-30 bus test system and compared with the popular Genetic Algorithm (GA).
