Abstract

Power system planners have come to rely on FACTS devices to overcome several operational limitations in terms of thermal stability, voltage stability, and other inherent limitations offered by the transmission lines. One important aspect that has always intrigued the power system planners and researches alike is in regard to the location and sizing of FACTS devices. This work aims to address this intriguing question by identifying the optimal location and size of the Static Var Compensator (SVC). The optimal location and size is proposed to be identified 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 analysed for an IEEE 30 bus test system.
