Optimal placement of FACTS Devices to reduce Loss and improve Congestion in Transmission System using ABC Algorithm
In this paper, Flexible AC Transmission Systems (FACTS) devices are used as a powerful tool for controlling power flow in power system to reduce active power losses and manage transmission lines congestion which are two main factors to restrict transmitted power in the network. Optimal location and size of these devices are specified by using artificial bee colony (ABC) algorithm which is one of the most effective method for solving optimization problems by taking into consideration minimizing active power losses and transmission lines congestion as objective functions in order to relieve the line loading of the overloaded transmission lines and increase the loadability in the transmission system. The proposed method is also able to improve voltage profile in the network. The effectiveness of proposed method is tested with IEEE 30-bus system and the test results are evaluated.
