Transmission power loss reduction using intelligent techniques-regulated IPFC

This paper compares the ability of various intelligent search algorithms in tuning interline power flow controllers (IPFCs) to diminish the transmission loss in power system networks. The IPFC belongs to a family of a series of compensating flexible alternating current transmission system (FACTS) devices and has the ability to manage power flow among multiline transmission systems. It has voltage source converters (VSCs), which can be adjusted to regulate the power flow in a corresponding line. In this paper, a study of the capability of IPFCs to reduce transmission loss is established. First, a general introduction to the FACTS devices is developed, and the problem at hand is defined. Next, the selection of parameters of the IPFC controller is considered as an optimization problem and the parameters are tuned by applying three intelligent search techniques: 1) differential evolution (DE), 2) artificial bee colony (ABC) and 3) particle swarm optimization (PSO). Finally, the effectiveness of the device in diminishing line loss is demonstrated using MATLAB® software application.
