A Solution to Optimal Power Flow Problem using Artificial Bee Colony Algorithm Incorporating FACTS device

Abstract

This paper presents an intelligent foraging behaviour based optimization approach i.e. artificial bee colony (ABC) algorithm for achieving the optimal power flow (OPF) problem solution incorporating the flexible alternating current transmission system (FACTS) device which is static synchronous series compensator (SSSC). The SSSC consists of a solid-state voltage source converter with gate turn off (GTO) device, a dc link capacitor, a magnetic circuit and a controller. The injected voltage is in quadrature with the line current and emulates an inductive or a capacitive reactance so as to influence the power flow in the transmission lines. The effectiveness of the approach has been tested on IEEE 14-bus system with and without SSSC. Results show that the ABC algorithm gives better solution to enhance the system performance with SSSC compared to without SSSC.
