Abstract
Full capacity cannot be exploited in power systems for various reasons, including voltage constraints and various types of stability. Creating a competitive open market in refurbished systems requires that the maximum capacity of the lines be used. Using the maximum capacity of the lines may cause overload on some lines beyond their capacity. This phenomenon may result in some limits being exceeded. Therefore, it is necessary to manage the line load correctly. One of the suggested ways for this purpose is to use FACTS devices in the power system. The various capabilities of the FACTS devices have made it possible to set different targets to determine their optimal location and position. Some of the most important placement targets include increasing voltage stability, improving voltage profiles, reducing losses, increasing line capacity limit and reducing fuel costs for power plants through optimal power distribution. In this paper, the placement of FACTS devices in the power system is conducted to increase the load capacity limit of the transmission line, as well as reducing the losses using the artificial bee colony algorithm. The artificial bee colony algorithm with high accuracy and high convergence speed is suitable for conducting FACTS placement studies. Finally, a comparison was made between the artificial bee colony algorithm and two particle swarm and genetic algorithms. The results indicate that the artificial bee colony algorithm works better than the other two algorithms in minimizing the objective function.
